Good sleep, good learning, good life (2012)

I think a lot of it has to do with mental status, which can be concluded with one sentence -- "Are you happy with your life, and if not do you have a clear path to reach that?".

People who say no probably has a lot of trouble to get fit, get enough sleep -- sometimes NOT because they do not have the resources, but because they are not happy. They hate life, so why makes it better? I have observed this in myself so I wonder whether it is universally true.

I have observed that whenever I have a clear target in my life (e.g. I need to pursue this girl I like, or, I need to figure out Linux 1.0 VFS and I have a clear path before me), I immediately take care to do exercises, eat more healthy food, and try to get good sleep -- but if I cannot find an objective, or I have lost interests and are in the middle of finding a new one, I find myself a lot more obnoxious, and sometimes I "proactively" destroy my health because I don't care about it. Unfortunately I rarely find a clear path before me so the later status is more or less permanent while the former one is rare, maybe once per year -- but when I reach the first status it usually grabbed me for 2-3 months.

Mental stability is probably one of the reasons different people have vastly different productivity or achievements. It is mental stability that brings focus, not the other way around.

I agree. In my case I am physically very fit but sometimes neglect my health in other ways, including mentally and definitely including poor sleep habits.

Regarding what you said about focus, I think an ADHD diagnosis might help a lot of people here. I suggest asking for a full profile including WAIS testing, which assesses intelligence, because it is the "deficit" between various types of intelligence and attention that matters. Highly intelligent people sometimes are overlooked because their focus, working memory, etc. seem normal or even better than average, but the gap between those and their intellectual capacity creates a lot friction at least for some people.

I recently got diagnosed and am really looking forward to taking a low dose of stimulants in the mornings on work days, I hope it will help me "find a clear path" in my professional life.

What drove you to get the diagnosis?

My wife was diagnosed within last 2 years and thinks it has changed (and helped) her come to terms with a number of behaviors. And learn how to resolve/improve.

I wonder about me, too. Haven't done it. Is it the case (honest) that may we all have just a little bit anyways?

Hear me out on this, while it often may seem to be the case that it looks like everyone has it, it very well may just be that you unknowingly choose your surrounding in a way that simply everyone around you has it.

How do you concretely get a diagnosis? Do you just ask your doctor for one?

by throwaway_987

4/16/2026 at 12:34:21 AM

yep, or call a clinic that does it. Search for MOXO, DIVA 5. The most important part is education. Sure, the medication helps, but understanding the root causes of mood swings, motivation, executive functions, hyperfocus, perfectionism, and emotional dysregulation is so important.

Educating yourself on how the brain works, the most important organ, is hugely underrated. Imagine playing a game with only half the screen visible. You wouldn’t see your stats, enemy info, or the map. It would be frustrating to play.

On the other hand, outcome-driven fitness (pursuing a goal like "i want to get shredded") never worked for me as well as process-focused.

I have strong legs not because that was a goal, but because I fell in love with cycling and never set ANY goals, just enjoyed getting out and riding my serotonin machine.

That might be more sustainable for some people, but if your interests/hobbies are constantly in flux (which mine are as well to an extent), maybe not. I need to find a way to enjoy the process of sleeping more.

by efskap

4/16/2026 at 12:16:01 AM

I wish I could be like that. I'm more or less a result-driven person, but whenever a result is achieved (e.g. complete all xv6 labs) I became lost and frustrated, and was eager to find the next one. But my mind was usually burnt out during the previous process, so it usually takes a few months of frustration to get everything settled so that I could move on.

The "pinball" concept in "The Soul of a New Machine" rings very true to me -- "The motivational system is akin to the game of pinball, the analogy being that if you win this round, you get to play the game again." -- this is exactly what I feel. But the pinball game is more and more difficult, sometimes too difficult for my fragile mind -- and I still have a day job and a family to take care of.

Same here, I guess this mode caters to specific type of personality (not obsessive about goals, achievements, not constantly comparing against others - at least I am none of those).

I like going to gym for past 15 years, it feels great to do some free weights. Not destroy myself, just a good workout. Body adjusting/maintaining not-a-bad-shape is a nice bonus.

by kakacik

4/15/2026 at 2:56:23 PM

In my case, I often find life goals and enjoy the journey when I'm mentally healthy, not vice versa.

I can't control my mood, but when I am positive, I start a new hobby like dancing or playing an instrument, cook healthy, lift, sleep well, study new things, etc. But when I'm depressed, I lose all interest in my life goals, eat junk food, skip exercise, and browse the Internet all night. I can't even enjoy my hobbies anymore.

It's always my mood that comes first, then I can find life goals and naturally do all healthy stuff.

Funnily, when I'm mentally healthy I also visit Hacker News frequently, but when I'm depressed all I do is infinite scrolling Reddit/TikTok.

4/15/2026 at 3:13:22 PM

That could definitely the case. I can't really tell which one comes first, mood or objective.

by hnthrowaway0315

4/15/2026 at 11:22:03 PM

It could be a bit like that elusive thing called motivation. "Just do it" seems so annoying when people say it but in my case sometimes its the only way to start building momentum. What im saying is dont wait for mood, perhaps the mood will develop once you obtain momentum on a goal or task.

by globalnode

4/16/2026 at 1:52:58 PM

Yeah I do hold this attitude and try to side brush "mood", which I believe is a mere suggestion, not a command. However I noticed a completely different "mode" when I'm operating IN project and BETWEEN projects.

When I'm IN project, "just do it" works very well. But when I'm BETWEEN projects (this is when I completed a project, and dived into the next project, but found out that I did not enjoy it or got lost or whatever), "just do it" only works when "just do it" -- it doesn't really create a focus needed to move the projects forward. What I got frustrated is that this IN BETWEEN period could take multiple months to get out, which is a super waste of time. If only I could figure out as soon as I completed the previous project, I'd achieve so much more -- you see, for the type of projects I'm working on, I could not afford to wait for several months, or even several weeks -- because this is not my daily job, so if I wait for too long I'm going to lose the knowledge -- it's like muscle training, you can't stop for several weeks and hope muscle retains.

by hnthrowaway0315

4/16/2026 at 12:34:58 PM

I use the “just do it” trick a lot myself. It was something I discovered when I was in my early 20s, hiking the Appalachian Trail, which requires you to get up and move every day. My partner and I did not have much money, so if we failed to finish, we would not have a second chance. I remember waking up one morning after a rainstorm, realizing that I left my boots outside the tent. They were cold and wet. Putting them on was going to be unpleasant. I thought “I just need to do it so that I can have other things that I want in my life.” Something clicked in that moment. Now, whenever I don’t want to do something I ask “does it help me do or be what I want?” It helps a lot. From big goals (eg, earn a degree, get the job I want, etc) to little tasks (take out the garbage, clean the toilets, etc). Oddly I find the little jobs to be the hardest, probably because although I recognize that living in a house with clean toilets is something I want, it’s not obviously connected with a motivating goal. This mental trick is very helpful for the little tasks.

It really is. Exercise and eating well was an activity I became capable of participating in as a result of the correct therapy and dramatically boosted its effects, not something I could persist at when already depressed.

When people claim the contrary it's feels more of a test to see if you can be perceived as responsible enough for your own actions to be worth helping. An individualistic mindset like that isn't very productive at alleviating depression.

by doright

4/16/2026 at 9:08:55 AM

Have you been to therapy? What did it look like? I'm thinking about getting one, but I'm not sure whether anyone could fix me when I'm fundamentally unhappy about life -- but definitely not to the point to consider suicide.

by hnthrowaway0315

4/15/2026 at 2:57:29 PM

I think we're soulmates. You articulated so well what I think about my own approach or lack of approach.

> Mental stability is probably one of the reasons different people have vastly different productivity or achievements. It is mental stability that brings focus, not the other way around.

Agree, at least in concept. I'm aware that some of my perceived or real lack of of progress in some life areas is due to mental instability. Various forms of it, some more active than others or present than others.

A lot of mine focuses on career things. I've got a bank of knowledge and skills that aren't easy to replicate and a career track circled around those things, but lack (I think) the passion for that career track.

But do I like the passion or do I just not have clear goals? What should they be?

In 2022 I was evaluating a senior position at a start-up and a friend asked: "what are your goals, or what are you solving for." My wife asks this question too.

And I tend to stare somewhat blank at the question. As an adult, the goals I'm sure I want have much less to do with career and much more with self. Be happy. Be productive. Be a warm and loving person. Be a responsible, fun, constructive parent.

That doesn't mean that I don't want a career or have aspirations, but there's so much less clarity. And so I've resorted over time to likely unproductive/destructive approaches - more argumentative than necessary, sometimes very responsive, sometimes unresponsive, substances and behavioral things that look like bad habits, addictions, etc.

What do you do to work through these challenges?

by grvdrm

4/15/2026 at 3:52:30 PM

Work to live, not the other way around. Work produces income and is a means to an end.

Drill down a couple of levels on what it means to you to be happy, productive, warm, and loving. What do an ideal day and week look and feel like? What kind of life would you like your kids to have? Not abstractly. What would their ideal school situation be? How far from school? Any special opportunities like certain clubs, interest in playing an instrument, sports teams? Do you just do weekend warrior stuff, or does being a responsible, fun, constructive parent mean you’re picking them up after school regularly to go make memories?

Let’s say it’s something like the last bit for a moment. “Begin with the end in mind” is one of the 7 Habits of Highly Effective People, and in this case, the end is being a fun parent by going for ice cream or to the park or watch a movie or take guitar lessons together a couple of days a week after school. To make that happen, you’ll need to have flexible work hours and maybe a work location near their ideal school. Do the rare and valuable knowledge and skills that you’ve accumulated allow you do that? If so, great! You’re passionate about being a good parent; you don’t need that from your job. Your job is a means to an end. If the current conditions of your job get in the way of your goal of being a responsible, fun, constructive parent, how could you modify job parameters?

There’s no right answer. There’s your answer. What do you want for your kids? What do you want for you and your wife now and after they’ve left the nest? Walk around in a day, a week of that life in your head. There’s your end. Work backward from there.

I think maybe you can move into a managerial position that doesn't need to do much in the trench, or become a trainer in that field.

> That doesn't mean that I don't want a career or have aspirations, but there's so much less clarity.

Yeah. I figured there is a lot of ambiguity in life objectives, and there is no one there to help you. You just have yourself in this game.

> What do you do to work through these challenges?

TBH, I do not know what to do. I have a toolbox for the "down" time, but neither of them really solves it. Sometimes I listen to "Napoleon Hill" episodes to give me some motivation (this one I listened to today: https://www.youtube.com/watch?v=7u5jAzHpI3w). Sometimes I talked to myself and tried to sort out something. Sometimes I talked to ChatGPT and asked it to give me a list of something.

I kinda think there is no magic pills for such situations and one just has to grit through.

by hnthrowaway0315

4/15/2026 at 9:25:49 PM

Maybe grit is the answer. I don’t know. I agree that to some degree momentum of any kind helps break a rabbit-hole moment. But it’s not that alone that always solve the problem.

One thing I know helps. Keep talking to people Keep conversation flowing who buddies, connections, or new acquaintances.

So happy to find ways to connect here too if having a sparring moment during these moments helps!

by grvdrm

4/16/2026 at 9:20:47 AM

I agree. It's just a tool that may or may not be useful. I also found that getting rid of caffeine for a couple of weeks, and then take up a cup, gives a much larger boosts to the mood.

by hnthrowaway0315

4/16/2026 at 12:50:24 PM

I wonder if it would help thinking through what makes you feel satisfied. I think many of us feel a bit crushed and demotivated when the reason to get up every day is extrinsic: taking care of somebody else, solving problems for somebody else, etc. Even if you are skilled at those tasks, it can feel pointless even if you recognize intellectually that they are important.

I’ve always felt that there was a big difference between doing something and doing something well. My grandfather, who grew up in an immigrant family on a farm during the Great Depression, used to say “do it well or don’t do it at all.” And it showed in his actions. He would spend enormous amounts of time doing things that just did not seem worth it to me at the time; eg, he obsessed about growing flowers when he had all these other skills that could be making him money. When I finally understood what drove him—that nearly any task can feel worthwhile when you move from simply doing it to doing it as best you can-it changed my relationship with work and other tasks in life. Another commenter here suggests that you should “work to live” and not the other way around, but I don’t really see them as separate. If you have the quality relationship with work in mind when you do it, when you connect it to doing things well, it’s hard to avoid feeling like your actions are also a part of living excellently, and for me at least, that fills me with a tremendous feeling of satisfaction.

by raddan

4/16/2026 at 2:41:56 PM

I was a bit skeptical about “do it well or don’t do it at all.” but then I realized my father is like that and then I understand. He might be a bit messy about very small things in life, but he is dead serious about anything else. The "smart" part is just NOT do anything you don't care, it seems.

For me, I wish I could be like that. I definitely need to work harder to achieve that. I tend to gloss over anything I don't like. Maybe that's why I never learned to grit through in my 40 or so years of life.

by hnthrowaway0315

4/15/2026 at 3:25:28 PM

I’ve always envisioned those states as ‘swimming’ versus ‘treading water.’

The deal I have with myself is that it’s okay to tread water for a while - if you’re tired, if you need a break, if you’re not quite sure where to go next - but you can’t wait too long, because the current will move you wherever it wants. To get where you want, you’re always going to have to start swimming again.

This is the type of hen-egg dialectic that takes me straight to evolutionary theory. My guess is that the 'standard human tribe', ~200 strong, needs some people to be up at night. But since we don't have dedicated day/night humans, we all get this shared mess of a genome 'you need to be up at night sometimes'.

Or it could simply be that you perceive your life as more happy and can find clearer goals when you exercise, eat healthier food and get good sleep, which is overwhelmingly the case and pretty obvious once you once you stop treating willpower as if it can magically stand in for unmet physiological needs.

by gobdovan

4/16/2026 at 9:06:55 AM

For me there is definitely a blocking factor, like awaiting for a click, before I can move into exercises and healthier food and such. Maybe it is a rare case and I do wish it is the other way around.

Actually now that I think about it, "The Soul of the New Machine" / "Showstopper" both describe this kind of mental (although I'm far from a good engineer) when engineers are done with a project, they get frustrated during the waiting period between two projects. This is pretty similar to what I felt -- whenever I finished a project, I tried to find new projects to work on immediately, not want to lose the momentum, but frustration quickly mounts among 1) I was burnt out temporarily but could not take a break, and 2) It's hard to find projects suitable for my level. It usually took a few months for this frustration to pass, which is frustrating by itself.

by hnthrowaway0315

4/15/2026 at 7:56:12 PM

Most people who are not happy are not happy precisely because they can't find a clear path to reach happiness. It's the realization you are stuck in a shitty spot that makes the true feeling of unhappiness. A lot of people are also restricted by their own body and mind through mental and physical illness which makes pursuing basic goals frustrating not rewarding. Also a lot of people get rejected when they chase girls and fail when they take IQ tests or pursue high paying work.... I guess your worldview makes sense for smart winners but how does it work for the other half of the world?

by stringfood

4/15/2026 at 8:23:26 PM

I'm actually neither smart nor winning, at least from my perspective. The only winners are those who can do whatever they want and can say No to anything they don't enjoy. There are very few of them. The majority of the rest of us are similar, regardless of whether you are making 100K or 500K. Then there are the homeless/jobless people who are struggling with basic needs.

I'm not sure which half you are talking about, but I'm really bad at giving advice, especially to people in different situations. I do not have the authority or capacity to help others genuinely.

I used to be able to do this but after having kids they always seem to reset the clock before you can make any headway. I still have not figured out how to regain the clarity. There is no substitute for unobstructed long stretches of time to focus on something. Being unexpectedly interrupted or put on a schedule just ruins it.

This comment is obviously true but uninteresting if you don't elaborate further on those causes

What I mean is, the comment you replied to isolated a specific cause and sparked a discussion; your comment, if taken at face value, is thought-terminating. How can we possibly comprehend all causes of complex phenomena before we are allowed to discuss them?

About the universally true thing, I understood it as whether people that's unhappy with life generally have trouble sleeping, not whether everyone that have trouble sleeping is unhappy with life. Still probably not an universal but is more reasonable sounding

by nextaccountic

4/15/2026 at 6:48:26 PM

The comment I replied to suggested that people who are not fit or suffer from sleep disturbances are willfully unhappy. I don't feel it requires much thought or experience with the subject matter to see that this is false. There are many easy counterexamples which I'm sure you can come up with even if you are only barely determined

No one is disallowing the parent, you, or anyone else from discussing or thinking about complex phenomena. If someone is not putting in the work to engage with the material, others are free to point it out, and they do so at their leisure.

I hold others to a higher standard when the stakes are higher. Specifically, the post I commented on was (likely unintentionally) not only factually wrong, but stigmatizing people with sleep disturbances. This is why my tone was dismissive and condescending. This was intentional.

I don't care to give examples because they are easy to find if you are asking in good faith. I even posted one in direct reply to TFA.

How can I explain to my 6 months old girl that we all need to sleep :D

This is a bug in the universe! We need to sleep so that the levels of dopamine, and hormones of hunger and not hunger are at good levels, so that we can be healthy and strong, so that the immune system is stable and strong... And we need to get good sleep so that we can protect our children and be sane....

BUT the nature decided that the kids will wake up 3-4 times per night, and you need to wake up and take care of them.

You sleep in best case, on pauses, not more than 4-6 hours, you feel miserable, and at the same time you are THE HAPPIEST PERSON IN THIS WORLD! :)

by sminchev

4/15/2026 at 11:11:45 AM

In my area there is a saying like "it takes a village to raise a child". i believe that a good social network is not only important for the kid, but for the parents too. it helps so much to have a partner, grandparents, aunts/uncles, who can look over the kid just for a hour or 2, so you can get your rest. And its usually fun for the kids too. Now that i have 2 kids, a loving wife and 2 families around me, i have the highest respect for all the single moms/dads out there.

by VanTodi

4/15/2026 at 11:27:48 AM

As immigrants with no local network, having kids is basically putting yourself under house arrest for a decade or so. You can post bail (pay a babysitter) for occasional reprieve. I mean sure you can go do outings with kids, but for most of them, do you really want to? I know mine aren't particularly enthralled by trips to the Rijksmuseum.

I don't think this is how humans usually raised kids...

by CalRobert

4/15/2026 at 11:48:53 AM

We're in the same boat. Feels like mostly our society doesn't value having children - it's by and large not a very well supported activity. Even more so if you don't have immediate family to help support you.

If you go to the third world kids are all running in the streets while both parents work and grandparents not doing fuck all to watch them either.

I've got a Mexican American friend that lives multi-generationally and loves it. He's a few years out of high school with a good job in management and a nice car, money in the bank. His older brother gets help parenting from Tio and the grandparents, and generally everyone gets along well. He's almost kept up with me in savings for property and I'm married (our pay is pretty similar, but I have dual income). American culture optimizes for wastefulness and puts too much of an emphasis on independence, especially when arrangements like this exist that actually can lead to greater individual freedom in the long run.

I read an interview once with an American woman who moved to Italy with her Italian husband. They lived in the same apartment building as her in-laws and in the morning her son would walk down to Nonna's for breakfast.

I love the idea of family living within walking distance but in their own domiciles, like townhomes or apartments or condos in the same building. This is another great argument for mixed zoning. A 55+ condo building in the same neighborhood with single family homes for large families and smaller townhomes/apartments for families that are just getting started.

We are living on a Farm. So we have a huge main building where the aunts and grandma lives and we live in a different building. Kids can just run over, since it's no road in sight and everything. I feel rather blessed

> This is a bug in the universe!

Is it? Couldn't it be a bug in our society/economy instead? What if nature wanted us to take some naps through the day and not just one period of sleep in the night? Waking up multiple times at night wouldn't hurt too much then.

It's also a fairly recent phenomenon that we expect small children to sleep all alone in a big room without anyone else around them. Nature tells them they are small and the world (and the dark) is full of danger. Our biology doesn't give a damn if that is no longer true.

FWIW, and understanding that individual babies do differ, most babies can sleep through the night (10-12 hours) by 3-4 months old. Check out the books "Twelve Hours' Sleep by Twelve Weeks Old" or "Precious Little Sleep" for guidance.

In my case where n=2, naps during the day are/were not all that consistent but at night (unless they are very sick or something) the kids sleep.

by johnthedebs

3 for 3 sleeping through the night by 60 days. All we did was have a feeding schedule that we stuck to pretty closely, and around week 2 started intentionally delaying our response to night-time crying, gradually increasing how far we stretched it (start with maybe a minute, increase over time). They wake up at night and don’t know how to self-soothe back to sleep if you always jump in the second they make a sound, they don’t actually need night time feedings past the first few weeks, responding immediately trains them not to fall back asleep on their own if they stir at night (and everyone does). Down to one feeding at night by a month or so, none past two months.

Can’t say many other things worked equally well for all three kids, but that did.

Love to hear it, thanks for sharing. I only wish there were more parenting "tricks" like this that gave similar quality of life improvements.

by johnthedebs

4/16/2026 at 5:29:56 PM

There might be, but we didn't find many of them. Lots of things that work just how the parenting books et c. say they should on one of the three kids, and not at all on the other two.

This is one of the very-rare things that actually worked for all of them, almost exactly the same, all three times.

I'd say the only other things we did that worked 3-for-3 were making the kids walk on their own early and often, as much as feasible, and never having snacks (nor, very relatedly, tablets/phones) for them on-hand when out e.g. running errands—we just never introduced that as even a possibility. We didn't end up with kids still stroller/carrier-dependent past age ~2, and our kids have never had a meltdown[0] or complained about a lack of snacks (or digital toys) when we were out running errands. We reaped benefits by not needing to cart strollers and carriers around nearly as much, and never having to worry about snack-logistics or related mess (God knows we have plenty of other messes to worry about). IDK whether or how much those approaches benefited our kids, but they sure benefitted us.

[0, editing this in] To be clear, each went through period where they'd occasionally have public melt-downs, but never because we ran out of snacks or had the wrong snack or whatever, or because we wouldn't give them our phones to play with. I suspect short-circuiting these exact sorts of meltdowns is how the snacks-in-stores and sitting-in-the-cart-with-a-phone situations come to be (aside from some parents seeming to just think young kids need food available constantly or they might starve? These people baffle me, but do seem to actually exist) but our general rule we followed whenever possible was not to lean on a crutch that we didn't want to end up needing forever. That principle served us well, I think. Tens of embarrassing minutes we might have avoided, but that saved us a ton more hassle later.

I’m convinced that 1 of 100 babies sleeps miraculously, magically, the true sleep of the just, right out of the box. Some lucky parents of those genetic freaks think, “Our sleep technique works! We should write a book!”

by sonofhans

4/15/2026 at 5:10:15 PM

In our case(s), it was something that required conscious effort. And when we did that... it worked. It honestly didn't seem like it would at first, but then it does.

Again, n=2 for me personally but as I mentioned in my reply to another comment we also had a friend with a "baby who won't sleep" and when they tried it also worked for them.

I don't make a habit of recommending this to people unless I'm close with them, bc I know that some people may take it personally or believe they are an exception. And I'd bet money that there are plenty of exceptions. But I also think they're exceptions rather than the rule. Whenever I've seen parents who believe that their baby can sleep through the night and work towards that goal, they seem to get there pretty quickly.

Edit to add: To put it in engineering terms, I think part of the problem is that you have to escape a local maximum of baby sleep. You may suffer several nights (possibly a couple weeks) that are worse than what you're used to in order to get to a place that's significantly better than what you're used to. When you're already sleep deprived, that can feel like a big hump to get over.

by rimliu

4/15/2026 at 2:24:31 PM

To be clear, they don't eat/feed at night either. The baby is in a separate room from us and we don't see or hear him most nights (95%+) between 7pm-6am. He's around 8.5 months old now and this has been the case for 3-4 months, although that percentage was a bit lower at the beginning.

I'm emphasizing it bc many people are surprised by this, but if you know it's possible, you can start to work towards it. My partner's coworker has a ~1 year old who was still waking up (maybe multiple times?) each night to eat. She introduced them to one of those books (the 12-by-12 one) and they were very grateful.

by johnthedebs

4/15/2026 at 8:15:15 PM

4 month old should eat every 3-4 hours. You mentioned sleeping for 10-12h and this sounds almost harmful for the baby. I don't think I'd like that.

Thanks for your recommendation anyway. I'm sure that there are many science-based techniques to "tame" children and make child care as atomic family bearable.

by integralid

4/15/2026 at 10:07:01 PM

If you saw our baby, you wouldn't be worried at all that he's being underfed. Maybe the opposite. They'll want to eat every 3-4 hours during the day for sure; at night they can and do just sleep through it (same as me or you).

We didn't force anything or ignore him. And you don't have to believe me, but I'd encourage you to research more for yourself if waking up at night to feed a baby is something you're currently dealing with.

Last month there was a heartbreaking news about a < 6 month old baby being snatched away by a leopard while the baby was sleeping next to the parent and the parent realized her baby was missing only much later.

I imagine the predator situation would have been much worse during the early human evolution years. I don't know if that was a beneficial trait or not in that environment.

As a parent, I just wonder what-if.

Part of this is also our culture that somehow decided kids need their own bed, and it's easy to get baby formula.

So the kids are not sleeping in our beds, where they feel 100% secure, getting to the breast whenever they want (and they quickly will want it at a lesser frequency). The woman will feel this, but hardly has to wake up, me... I slept right through all that. Fwiw, we had a bed for the baby that attached to ours.

In our time everybody advised us: Give the bady a load of milk at 23:00 just before you go to bed! We never did, just stuck to about did 20:00, or just when baby cried, both babies took about 2 months to sleep for about 12 hours straight (although soon after the second one developed reflux which had me watch Rick and Morty in its entirety somewhere between 2 and 4 for some time).

Anyway, not saying everybody is that lucky, just saying sometimes it's good to questions things that are given in one's culture. Worst advice imho is "let the baby cry" which was common on our days. How nice to let a baby cry alone in a room, not understanding anything about what happens...

by teekert

4/15/2026 at 2:17:14 PM

I coslept, but I had shit milk production. Without formula my kid would be dead. My friend breastfeeds, but is an active danger when asleep, so without a crib, she'd have crushed her child.

It turns out that safe sleep rules and the availability of formula exist for a reason. Safe sleep rules exist in the west because pur beds are fundamentally different (and more dangerous) than in places here cosleeping is more common. Tp cosleep you need a certain situation that many people are not prepared to deal with.

There's literally nothing you can do about low supply at all. It's not a matter of trying for me. My body never made more than an ounce even with weeks of attempts. This is even setting aside that some people would like assistance so they can sleep and breastfeeding means dad can't take on night feeds, which is what another friend is experiencing and the child is having a bad time from her severe sleep deprivation.

And even more complications of small child. It's not as simple as "let's go back to the old days". The great days when kids died at much higher rates remember.

by iteria

4/15/2026 at 6:14:20 PM

Sorry, I did not mean it like that, formula is fine. We also hated the breastfeeding mob.

And you're right about the rules they exist for a reason, but I think we should as parents take our space to try what works for us and our kids and what feels right.

by teekert

4/15/2026 at 6:29:35 PM

Sometimes I just can't grasp how cruel nature is. Imagine no formula -> baby starving and you just have to accept it. When the tribe grows in numbers the baby is safe. When the tribe grows in numbers like mankind, you get cheats like formula and polio vaccine.

We're just replaying the life game on easier mode.

Somehow, neither schools nor parents prepared us in any meaningful way for the hardest challenges in our lives. School curriculums are next to useless beyond basic reading/writing/counts.

Where is self sufficiency, team work, communication, taxes, relationships, understanding various addictions, understanding other people, good nutrition, savings and retirement, and of course having and raising kids?

I get they dont want to scare shit out of clueless young, its certainly easier to let them hit walls of life and see who can swim and who goes down. But, as a preparation for life, school is useless and I believe it shouldnt be. I would love to see teachers having doctor's or wall street salaries but be proper experts and psychologists, all of them. Thats the future of given nation.

I would much rather have school teach the more "rigid" of knowledge, and society teach the more fluid.

I am recently diagnosed with Type II Diabetes.

The classic symptoms were unknown to me until this point when I researched them.

I had previously blamed psych medications for the symptoms, and while they may have exacerbated them, I guess diabetes was the real root cause.

One of the symptoms is frequent urination. And so, every night I wake up every 2 hours or so and crawl into the bathroom. It’s legitimately a huge curse.

I don’t get enough deep R.E.M. and I remain exhausted just from the physical effort of get-up-and-go.

It’s very frustrating and sad to think that even after I’ve got my blood glucose under control, I still have these lingering symptoms that impact my QoL.

Eat right, kids; eat well or be cursed for life!

by ButlerianJihad

4/15/2026 at 11:08:41 AM

IMO Type 2 diabetes is manageable. My father struggled with it for decades and his last few years were not great. Having those same genes, I've spent a lot of time reading and following the data. My take is that T2 is quite manageable. Even reversible, if you focus on it. "Reversible" doesn't mean a lifelong cure, but you can push out your health days by a decade.

There are all kinds of solutions that work. High Protein, Mediterranean, Atkins, or even High Carb (the "good" kind). The breakdown usually happens in the "cocktail" of foods. Our bodies are not hybrid engines; we can not switch fuels mid-stream and expect optimal health. You have to pick a poison, let's say, a protein-based diet—and stick to it. Then exercise and intermittent fasting (IF) are force multipliers. I did strict IF for a year, but I have fallen off the wagon lately, only manage 3-4 days of IF a week. The difference in how I feel is stark.

What worked for me was something called "Lalit Kapoor" diet — basically a WFPB/vegan approach with heavy green juicing and fasting. My failure was primarily due to social friction. My family eats very differently. Making a special effort for every single meal eventually made me start taking the easy way. I still follow it but I wish I could be 100% rather than 80% and which is where all diets fail.

by kshacker

4/15/2026 at 10:04:47 PM

The thing you might not be realizing is that sleep directly impacts your metabolic health. Yes, focus on diet, but sleep also drives diet desires. It's a vicious cycle.

Your comment about "not enough REM" sleep shows how little people truly understand about sleep. It's not REM (or even the amount of REM) that is the issue. REM is dreaming sleep and emotional processing. N3 and to a lesser extent N2, often referred to as deep sleep is the stage where the restorative activity and hormonal balance occurs.

by pedalpete

4/15/2026 at 10:16:24 PM

Fine, fine, I get it. I am sort of chagrined that sibling comments are missing the whole point, and that is about quality of sleep and rest.

Having C-PTSD incipient since my childhood, I've really never, ever known what it's like to have a good night's restful sleep, or a regular schedule of days awake and nights asleep. It's been completely elusive to me. Obviously it is one of the most important things I could do, but how?

by ButlerianJihad

4/15/2026 at 4:15:36 PM

Hope you find some relief.

I was experiencing similar symptoms in college, and self cured myself through: - diet shift and adjustment, keto and then carnivore specifically - shifting breathing to the nose: the sympathetic nervous system is activated through mouth-breathing, that leads to stress and anxiety all around bogging up everything from the digestive system, lymphatic system and more - happy to share more, my sleep schedule works best by following the sun and guarding myself from artificial lights exposure after

happy to share more as stated.

When I got older, night urination became an issue. But it doesn't happen as long as I control my liquids at night.

If you controlled your liquids at night, couldn't you make it nearly physically impossible to have to urinate frequently? Theoretically, it seems like you could resolve or at least significantly improve it like this.

by apt-apt-apt-apt

4/16/2026 at 1:58:27 AM

Look, I live in a desert climate, and it's essential to be well-hydrated. Yes, I could cut back at certain times; in fact it was 15 years ago when my PCP encouraged me to stop drinking fluids after 6pm.

I've also had a struggle with riding public transit for long, long stretches. Because you often do not have any opportunity to use a restroom on those journeys, sometimes for 2-3 hours. So it's a delicate balance of surviving 120℉ desert weather vs. "gotta go now!!!"

Furthermore, you should be aware that there are three classic symptoms of diabetes: polyphagia, polyuria, and polydipsia. That third one means "excessive thirst"! https://en.wikipedia.org/wiki/Diabetes#Signs_and_symptoms

So the diagnosis did explain something I'd struggled with for several years already: my nose, eyes, and throat were often drying out, not from a lack of hydration, but from the climate and simply chronic dryness. And I linked this to the polydipsia phenomenon. And again, I am thankful that I never got hooked on psychoactive drugs, because they all exacerbate these symptoms.

I have begun using Ricola throat balm lozenges to alleviate the dry-mouth symptom, because this often occurs even when I'm well-hydrated, and since I also suffered from hyponatremia, I do not want to guzzle excessive amounts of water!

So yeah, it's a delicate balancing act, whether I'm on a local city bus or trying to sleep in my own bed; how much am I gonna drink and how often am I gonna be interrupted?

The most important thing about sleep I learned is to fall asleep at the same moment of every day. Make it 22:00 or 23:00 or 00:00. Whatever is comfortable for you. But you have to stick to the chosen hour as hard as you can. Every day from now on it has to be that hour. After you get used to that you will notice a much better effect of the sleep.

by gitowiec

4/15/2026 at 2:01:45 PM

I agree with how important this is, but for me, the most significant improvement in my sleep has been pushing my dinner very early, ~6 hrs before bed, and having it be my smallest meal of the day. I usually feel quite hungry about an hour before bed but if I get over that hump my resting heart rate is much lower at night and my appetite the next day is much lower. It was validating to see Bryan Johnson sharing the same findings on x.

by jelsisi

I think one of the underrated things that Bryan does is he regularly emphasises how central sleep needs to be in your health.

I believe that routine in general helps a ton. Go to sleep at the same time, eat at the same time, go for a walk at the same time, etc. You will wake up at the same time as a side effect. At least that's what happened to me during covid, when there were no obligations outside of working hours. During normal times, I will stay up late one or two days a week for social events or have to get up early for travel. That messes with your rhythm, almost like being jet lagged.

by mr_mitm

4/15/2026 at 4:58:02 PM

Strongly disagree and you should refrain from trying to give universal advice on these matters. I never had a 24h circadian rhythm. The only way to fall asleep at the same moment every day for me would be to medicate myself. I am very happy and productive when I am allowed to "rotate around the clock" and the worst periods of my life were when I was forced to be on a strict schedule.

The most important thing with any health issue is to be aware of your own body.

by glerk

4/15/2026 at 10:16:23 AM

The older I get the more sensitive to a single poor night's sleep I become.

The most frustrating effect is that even a few drinks in the evening (maybe over 2-3 units). Unsettles my sleep that if I'm in the process of learning something feels like it sets me back several days.

That's not even counting the slowed processing I feel, and lower productivity the next day.

I genuinely have to revisit old information.

A genuine hangover from a heavy night can put me out of action for half a week!

When I was younger I'm not sure I had many good nights sleep let alone noticed a bad one!

I've heard that small amounts of alcohol can actually improve learning interestingly by preventing interference from events later in the day.

by rustyhancock

>The older I get the more sensitive to a single poor night's sleep I become.

Back when I was 20 I had a drinking problem. One time I drank so much that I passed out sitting at a table. Woke up with friends having stripped my clothes and washed them. I woke up at 9AM, feeling 100% sober, just anxious about my 20 missed calls from my mom. I got a bit drunk at about 33 and next day I thought I was dying.

That's how I learnt what hangovers were.

Again, at around 25, I helped my brother in-law move bee hives all night, including some 8 hours of driving.

Went straight to work and in the evening I had dinner with my wife at a restaurant.

Now I crash in bed at 9PM and if I'm lucky, I also sleep (but quite often I wake up at 2AM).

Getting old(er) sucks, and I'm only 42 and I miss so much how nice being in my 20 something body felt all the time.

I’m 41 and my body is nicer to be in than when I was 25.

Like you, I have much less youthful buffer that shrugs off poor sleep or overindulgence, but I have much more knowledge and much better habits.

Daily habits: better nutrition (based on Bryan Johnson’s super veggie and nutty pudding), stretching, weak points warmup, proper oral hygiene, regular bedtime

Weekly habits: 4x gym, 3x run, 2x weighted walk

Reminder for anyone that doesn't know better: having good sleep is dependent on a few minor lifestyle adjustments. Like avoiding heavy (or any outside of fruit and vegetable) meals and exercise a few hours before going to bed. And avoiding caffeine after noon.

You don't need to be a health champion to have good sleep.

Only if you don't have psychological issues, then none of that really works.

I’m 49 and have all but given up on drinking. It does nothing for me except make me tired and then, ironically, mess up my sleep. On fridays I grill cheeseburgers for the family and usually have one Half-Life tall boy from Manhattan Brewery because it’s my favorite of all time but that’s about it. Otherwise, I don’t drink at all. Being tired and not sleeping well is handled perfectly adequately by my job hah.

by chasd00

I'm pretty much the same as you. I really like beer and wine and cocktails, but the bad sleep and feeling shitty the next day after even one drink isn't worth it. Thirty years ago hangovers were rare and could usually be ended with a cup of coffee, tylenol, and lots of water.

The next thing I have to back off on is sugar. It doesn't seem to mess up my sleep like booze, but I definitely notice it the day after I have that big bowl of ice cream or giant slice of cake. A big enough sugar binge feels pretty close to a hangover for me now.

I'm not noticing it unsettles my learning but can relate to a few drinks already upsetting my sleep. I wouldn't be surprised if my learning would be impaired by at least a bit.

by mettamage

I'm in a similar age bracket.

Here is some research around the alcohol effect. What I found most surprising is the mean consumption was over 80g, since 8g of ethanol is a unit that's an astonishing mean of 10units.

I was of the impression that the effect was around 1 unit.

https://pmc.ncbi.nlm.nih.gov/articles/PMC5524957/

by rustyhancock

4/15/2026 at 1:22:30 PM

While there's no consistent standard, most countries appear to be using something in the 10-14g range for what they call a "standard drink"/"unit" of alcohol. (UK is 8g, but the rest of the EU typically uses 10g or 12g, US uses 14g).

I actually hadn't realized until I went looking that the "standard drink" isn't much of an international standard unit at all. Will have to keep that in mind when reading papers/recommendations from different health authorities in the future.

-----

Anyway, it's pretty interesting. I'm not sure I'm going to believe the effect just on one noisy study, but even if the reality is something lesser - like it just not harming memory formation of things you'd learned earlier in the day, the implications are still a bit interesting.

It certainly adds a bit to some of the historical social biases against "day drinking", and also does a bit to explain how plenty of high-performing young people seem to use alcohol pretty heavily after they're done learning (college students partying, etc) with limited direct impacts on their educational performance.

Even better, the topic is visited on part 6.2[1] of the article you're replying to.

Huh, that's much less than I expected! Apparently it's just for adult population (correctly). Apparently that varies from year to year (in 2024 it was 64%), and by race (highest in white people 70%). I also wonder how that looks when we exclude older people (let's say over 60) who more often have health problems or just tolerate alcohol very badly).

It's higher in my country so good to know that USA drinks less than I assumed.

I’m not religious at all, and it’s not religious fundamentalism to point out that alcohol disrupts sleep, and that this likely is the primary factor affecting the poster’s sleep.

Also not religious fundamentalism to point out that alcohol is a known carcinogen (: that’s just science. It’s a Group 1 carcinogen, the same group as tobacco and asbestos.

But sunlight is essential for the cutaneous conversion of 7-dehydrocholesterol to vitamin D3, whereas ethanol serves no essential purpose, irrespective of whether one enjoys it or not.

Personally I don’t consume ethanol; but I don’t care if others do or not so long as they stay off the roads and are not piloting my flight.

I will say that when I did consume ethanol even in small quantities, my sleep was much worse than it is at baseline; and that effect only worsened as I got older.

Ethanol is food— you also don't need carbs, but they do keep you alive. More importantly, it fairly central to cultural vitality. Not essential but it plays a highly functional role. Maybe could be replaced by religion or other drugs, but short of that, the world is less vibrant without it.

by Antibabelic

Advice like this turns almost everybody's normal state into a disorder.

"Go to sleep only when you are very tired" is a child's approach to sleep, it's what we all want to do, and by adulthood we learn that it's counterproductive. But we still want it so much that we regularly test it and are reminded why we don't operate that way.

It reminds me of the intuitive eating folks who say, "Ignore standard diet advice, just listen to your body and feed it what it knows you need," but then when you overeat, they say, "You aren't listening properly, you aren't in tune with your body." Then if you ask, "How will I know when I'm in tune with my body and listening to it properly?" they say, "When what it asks for matches standard diet advice."

I think nearly everyone should be screened for sleep apnea. The at-home test you wear on your finger is so cheap - it doesn't make sense not to do it for anyone who has any issues with sleep or tiredness in the day.

I always thought that due to being female and a healthy weight, it wasn't something I needed to think about. I also didn't think I snored more than anyone else, so it took me years of poor sleep before a Doctor finally recommended I get tested.

Turns out OSA also can be caused or aggravated by: the size and shape of your mouth, the position you sleep in (I have twice as many events on my back vs side), and whether you tuck your chin in near your test (soft cervical collar helped for that). There are devices that alter how your mouth rests when sleeping (easier to breathe if your front teeth are forward) but they're possibly not good for your bite. CPAP/APAP is still the gold standard for a reason.

The coolest thing about CPAP though, is a lot of them have amazing metrics recorded if you pop in an SD card. And there's a big community built around open source software to analyze those metrics and tune the settings to minimize apnea events overnight.

Also, a cpap with a humidifier is amazing if you're prone to nose pain / nose bleeds due to dry air.

My comment is more of a complaint than a discussion so apologies, but I was disappointed recently because I did at an at home test and scored borderline. I was hopeful that it would be sleep apnea so I could go about solving my bad sleep, but a lab test showed conclusively that I didn’t have it.

I got checked out initially because I mentioned to my sister that I didn’t recall the last time I’d woken up and felt refreshed all day, even with 8+ hours, and she said “…that’s not good, get that checked out.”

Back to the drawing board :(

Chronic tiredness can be such a hard thing to figure out, sorry you've been going through that! Is it sleepiness (as in can fall asleep at any point of the day), or fatigue (as in non-restorative sleep, brain fog, feeling exhausted, etc)? I've had chronic fatigue (non syndrome) for six years now, so I'm pretty familiar with how obnoxiously long it takes to get answers. Some things to look into:

Do a full polysomnogram with MSLT: this will check for sleep apnea, restless leg syndrome, narcolepsy, and idiopathic hypersomnia

Look into ME/CFS if you have post exertional malaise (pretty much you cross some invisible line in exertion followed by a delayed crash).

Look into MCAS if you also have strange allergy symptoms. I have MCAS, though tbh I didn't really have that many symptoms until I looked at Dr. Afrin's free chapter on MCAS.

Maybe fibromyalgia, but you didn't mention muscle pain, so it probably doesn't apply.

Obviously depression can cause somatic symptoms, so that's worth checking, but I think people jump to that conclusion too soon.

Note that a lot of these conditions don't really have tests, so it's really tricky to get a diagnosis. It takes finding a doctor who's willing to recognize them and give a diagnosis.

I have a somewhat rarely diagnosed circadian rhythm disorder called delayed sleep phase disorder. It is difficult to get diagnosed, especially as sleep clinics have been targets of private equity firms which convert them to CPAP shops which only diagnose sleep apnea and whose patients never interact with an MD. However it is likely to be underdiagnosed given the stigma around sleep challenges, at least in the sense that if you make any effort to get enough sleep with such a sleep disorder, you tend to be pegged as lazy, irresponsible, unreliable, etc

In any event, I agree with something implicit in the article, namely that most people have a degree of this, but the severity is variable. Mine has been fairly extreme, and while diagnosis enables disability accommodations, it is very fraught navigating most workplaces with this particular disability and you are essentially forced to choose between having any kind of upward mobility and getting enough sleep at night.

Thankfully the past two years or so I've been getting much more sleep since optimizing more for that. But anyway, if you are navigating sleep challenges you should get a sleep study, sure, but also be aware that your local sleep clinic is in all likelihood only nominally a sleep clinic. That is, it does not know how to diagnose and treat more complex sleep issues and probably doesn't want to.

by vector_spaces

4/15/2026 at 8:51:40 PM

I have DSPD as well, and was pleasantly surprised to see how much of the article discussed DSPD.

That being said, I do think a lot of what the author is saying flies right in the face of traditional advice, esp. the suggestion that we should all just free-sleep and rotate around the clock. I personally find myself happiest when I'm entrained to the 24-hour cycle, but at my own natural offset. Whenever I've been cycling the day it's felt miserable, uncontrollable and exhausting.

To be fair, the author did claim that you can fully solve this by completely cutting out after-dark electronics, but I've tried pretty intensely to do exactly that for extended periods in the past, and didn't see any progress. I do sleep amazingly when camping, though, and the delay is lesser than normal (still definitely there).

4/15/2026 at 2:05:25 PM

If only I knew how to have full non-interrupted restorative sleep. It seems that my body started losing that skill about 20 years ago, and lost it altogether about 6 years ago. The falling asleep time is a lottery and I'm always waking up after the first stage, often a few more times after that.

Tried all kinds of sleep medication, but by now I've forgotten what it's like to not be half-asleep and unable to concentrate throughout the day (with loud tinnitus and a soupy feel in the brain to boot). Really sucks out any and all enjoyment from life, I can't even find the energy to watch TV shows anymore, let alone read books. I haven't learned anything fundamentally new at work for years too (inertia helps with daily routine).

As a Spaniard I am trying to honor my ancestors and nap when I can, but man, it feels almost impossible most of the days. It could be that I am having too much anxiety/stress, too much coffee in the mornings, lack of practice, or maybe all of them. Any experiences related to learning to nap or what worked for you over here?

by amunozo

4/15/2026 at 12:07:24 PM

Fellow Spaniard here. Our ancestors were definitely onto something! I think the most important thing when it comes to napping is to show up: find a comfortable spot, use an eye mask, and set a timer for whatever time you have (I typically do something between 10 to 30 minutes). Just close your eyes and don’t open them until the alarm goes off.

I don’t always nap, but I make sure to do so if I haven’t had enough sleep or when I’m stressed or overworked. The more work I have, the more naps I take. Three back to back meetings? 15 minutes nap for your brain to organize and process the information dump. You get the gist. Doesn’t have to be after lunch, just a few minutes when you need/have them.

I used to do the Dali nap: find a comfortable spot, hold a spoon in your hand, and close your eyes. Once you fall asleep the spoon will fall from your hand and wake you up. That makes sure you go into hypnagogic state, great for problem solving as the brain is in a creativity sweet spot.

The technique I use now is not strictly a nap but a relaxation technique called NSDR: Non-Sleep Deep Rest. It’s kind of a guided meditation that deeply relaxes your body and nervous system. Just 10 minutes can feel as restorative as hours of sleep. You can check Andrew Huberman's scripts or Youtube videos for a more body-hacking, science-backed vive, or channels like are Ally Boothroyd's [0] for a more spiritual take on the concept, also known as Yoga Nidra.

I hope that helps. And best of luck with your napping, honor the ancestors!

Thank you so much for your detailed answer! I definitely try to show up, but I am an anxious person and sometimes trying to nap makes me even more anxious. However, it is true that even when I don't manage to sleep it helps relaxing me and giving me some extra energy.

I've also read about NSDR and wanted to try it, so having some sources is really helpful. Do you always practice it with some guided meditation or can you do it on your own? I kind of not like guided meditation. (No reason, it's just that kind of feel wrong. Probably I should just open my mind and try it more.) Thank you so much!

by amunozo

4/15/2026 at 1:50:40 PM

Practice makes perfect! Keep on showing up and it will most likely get easier :)

I currently do not do guided NSDR that much, but it helped a lot at the time learning how to calm my thoughts and become deeply relaxed, especially the Ally guided sessions (as everything else, takes practice) so I would recommend to try the guided ones even if it feels awkward, until you learn how to stop your mind from wandering. I find it helps both with quick reset/recharge naps and falling back asleep if I wake up in the middle of the night (happens often for me).

by nsbk

4/17/2026 at 2:59:00 PM

I'm trying to get into the NSDR and although I am not totally convinced, it is true that give some insights about calming down and it's easier that non-guided meditation. Thanks! I'll keep practicing.

Set a timer for 20 minutes, lie down (or at least close your eyes) and force yourself to stay motionless until the timer rings. Try to let your thoughts float freely... Sometimes it works, sometimes it doesn't, but you should try at least a few times. (And yes, maybe limit yourself to just one coffee in the morning.)

by isolli

4/15/2026 at 12:32:00 PM

I try, but apart from the coffee (I usually take two, probably the second one interferes with my nap), I think it's the lack of consistency/practice what's making my napping difficult.

Hm, no, non-24 is not just a severe version of DSPS. Or rather he seems to be saying DSPS is really just a less severe version of non-24.

I have it. What I've learned from my doc (a researcher in the field):

It's primarily a specific genetic mutation that affects many of they body's cyclic timers, but relevant here is that the circadian feedback loop is no longer able to lock to a 24 hour day/night cycle at all. The timer technically works. You're perfectly sensitive to light/dark, but you're hitting a PLL with inputs faster than its ability to make meaningful adjustments. That's not the case with DSPS.

Sleep apnea diagnosis is relevant here, it also breaks the breathing reflex timer. Imagine finding out at age 40 that you've not, in fact, slept more than a few minutes at a time your entire life, because you wake up just enough to take a breath every 3 minutes or so when a secondary suffocation reflex goes off.

I've never had sleep issues but lately I've been in a bit of a rut. I've always maintained a sleep schedule of going to bed around 00/01hs (not that uncommon in my country) and waking up around 8/9am. However lately I've been arriving VERY tired from work around 19hs.

It's very easy to fall asleep right after work and some days I go to sleep for a few hours but then I wake up super late for dinner around 10/11pm and completely screw my schedule, last night I couldn't sleep until 4am or so.

Most days I don't sleep and power through since I need to buy groceries, cook, do other stuff around the house etc. but even so after dinner around 9/10pm or so I become very active, I don't get sleepy and I can't easily sleep until 2/3am. I've tried with a bit of melatonin, magnesium, etc.

Moreover I've bought an apple watch and discovered I have quite some interruptions during the night, so I'm sleeping around 5-6 hours if I don't sleep at a crazy time, a bit less than what I expected.

Any suggestions? I don't know if taking that nap when I come back from work is helpful or not, usually I don't but I do feel quite tired during that time so I wonder if it's the natural stuff to do to try and go to sleep.

by fy20

4/17/2026 at 4:18:41 AM

I have multiple severe sleep disorders including non-24 and insomnia so it is hard to tell how my experiences match most people but hopefully this might help some. My sense is that when I sleep only a few hours then can't get back to sleep for at least three hours it means my body is interpreting the sleep as a siesta rather than night sleep (unless it is after sunrise). Non-delayed release melatonin makes this more likely for me. I don't think delayed release makes it less likely (at least not right away) but might at least not make it more likely and longer term it seems to help make it possible for me to sleep on a closer to fixed schedule. Magnesium is one of the few that helps me stay asleep though I suspect what might help you most is if you could take a nap earlier in the day. While most people these days already do this part I've found that caffeine in the morning makes it much less likely that I'll have this issue (I can't have caffeine in the afternoon or too much theobromine even in the morning multiple days in a row or I will have trouble sleeping; I imagine the helpful effect will be much less in people who are desensitized).

It sounds like you have a delayed circadian rhythm. The Circadian Sleep Disorders Network has some good info:

https://www.circadiansleepdisorders.org/

I don't agree with many of the suggestions in this article. Advancing your sleep schedule to try to shift your sleep earlier is particularly harmful and can trigger non-24. In my case, part of my body seems to be synchronized with light and part rotates around the clock leaving me rarely all that functional. It is a disabling condition. A somewhat delayed circadian rhythm seems to usually be much less disabling but may also cause similar trouble if severely delayed (many people don't have as much trouble with non-24 as I do, though I didn't have as much trouble for the first 15ish years either).

Waking up at the same time every day is another thing that can help stabilize the circadian rhythm (though I also think it is best to avoid alarm clocks most of the time). Going to sleep at the same time is less important; it is better to go to sleep early if you need more sleep than to sleep in.

I think it is best to avoid medication if possible. What I am using now seems to be working the best of anything I've tried but it has only been six months. At night I take 300mcg 6-hour delayed release melatonin, 250mg delayed release magnesium (though I think non-delayed may work just as well), 2.5mg baclofen (the small amount keeps it working with daily use and using it with magnesium works better than either alone), and 8-9mg diphenhydramine (not enough to help me get to sleep but just for the circadian effect, either 1/3 of a 25mg pill or 3.5mL of 12.5mg/5mL liquid). In the morning I usually drink some tea and take .5 tsp (2.5mL) D-ribose which seems to help quite a bit (I had previously tried it without noticing a positive effect but I think I may have only used it later in the day). In the US there seem to be many companies that package D-ribose but only one company that makes it.

Could be a symptom of poor stimulation regulation. I know that's the problem in my case. if I have a phone, screen, or even a book in front of me I can stay up until tomorrow. But, if I shut it all down (roughly 30 to 60 mins) before I actually plan to try and sleep it absolutely causes the tiredness to kick in.

I will say there are varying degrees of stimulation. Computer use > TV > Book reading > Music > silence and boredom. At least that is the order in which I shutdown on the nights I have the motivation to do so.

I got 4h of sleep last night which is about my normal average at this time of the year, and I have 0 regrets about it. I also don't sleep at a regular time every day. If I have no other obligations, I naturally let it shift forward (what the article calls "delayed sleep phase"). I am most unhappy when I HAVE TO use an alarm clock and break my own patterns. Last night, I naturally went to sleep right before sunrise and I woke up 4 hours later.

To pre-empt a few objections: I did not need an alarm clock to wake up. I am not taking heavy stimulants other than caffeine at this time. I am not stressed. I am not unhappy. I don't have memory issues (in fact, I am cursed with a very good memory and it is usually harder for me to forget than to remember). I can score above the Mensa bar on an IQ test. I can take an interview. I can give a demo. I can run 10km. I do not have "bipolar disorder" or any such nonsense. I don't need medication. I don't need therapy. I don't need a better mattress. I'm not already in a mental asylum. I'm married with kids, I work a high-paying job, I give to charity and I pay my taxes. In fact, today is tax day, I should probably take care of that instead of getting upset at hacker news comments.

I would suggest looking into the medical research on the downsides of getting little sleep. After a single night of low sleep (and 4 hours is low), even though you'll feel fine, your body will not process a lot of things the way it normally should (e.g. insulin response is significantly degraded).

Over time, it supposedly significantly increases the likelihood of certain diseases/conditions.

Peter Attia was one of those people who got by with little sleep, and for years, well into his medical career, was dismissive of those who preached the importance of 8 hours of sleep a day. He then looked into the research, and completely changed his mind:

When I was looking into the dual n back stuff a while back, I remember reading one report where the person would feel subjectively fine when sleep deprived, but his nback score would go way down.

In other words it's possible to "feel fine" on little sleep and yet be significantly cognitively impaired. Worth measuring that, if possible.

(It might have been Gwern, he's got a big page on the subject.)

I am not dismissing the research and I am well aware there are tradeoffs. I am aware that low sleep puts extra strain on the brain and the body at large. I am aware of the increased inflammation, decreased CSF draining, cardiovascular issues, appetite issues, insulin tolerance etc. etc. I know that our bodies were optimized by evolution to function better with sleep cycles synced with circadian cycles, and I know that many of these very well optimized processes are put under stress when you sleep less than 6h per night.

Here's the thing: say what I have is a "disease" and currently, the best cure for this disease is a pill that would slow down my thoughts and make me into a bland emotionless vegetable during my waking hours in addition to reducing the amount of waking hours that I get to enjoy. Even if that magic pill buys me 20 extra years of old age at the tail end of my life, is it rational for me to take it in my early 30s?

That's totally fair, and I'll cross that bridge when I get there like everyone else :)

My philosophy is: either I'll live to benefit from technology that can repair the damage caused by aging, in which case health micro-optimizations early in life are not that important, OR this won't be achieved within my lifetime, in which case I prefer a short life with concentrated happiness, vitality and intensity in my youth.

There is some new scientific finding that in deep sleep, fluids from the brain drain out and if that flushing doesn't happen, it might lead to Alzheimer's disease.

You should at least monitor your deep sleep using a smartwatch. Less than 1.5 hours and I would be worried.

Thanks, I am aware of reduced cerebrospinal fluid flushing as well as the increased neural inflammation in general and I am trying to compensate for that as best as I can.

I am not too worried about Alzheimer's as it tends to start pretty late in life (I think average onset is around mid-60s?). If I get that and we don't have a reliable cure by then, I wouldn't really mind ending it quickly after getting the diagnosis. I'm a bit more worried about heart disease as that tends to hit earlier.

I'm extremely sensitive to poor sleep. I also have nothing in my schedule that really prevents me from going to sleep early and sleeping late most of the time, and generally I at least achieve the former. The problem is that I have unbearable horrible nightmares every time I sleep. To the point where going to sleep is akin to going to hell itself, and I generally choose to forcibly wake myself up around like 6 a.m. just to get away from it all. I haven't really figured out a way around this.

I have as a kid. It might help you. As a kid, I instinctively (and later also consciously) have trained myself to become lucid while dreaming. When I become lucid, I gain some power. Then I trained myself to be more powerful in dreams.

For example, I can't fly, but I can (apparently) move the whole universe by a specific offset. I can also change the specific offset at a specific motion. So basically, I don't have flying powers, but I do have the powers of treating my dream like a Unity3D scene. And in that way, I can mimic flight.

I can also turn into a monster myself, usually into a worse monster than whatever I'm facing. I have become my nightmare's nightmare at certain points.

Nowadays though, whenever a nightmare hit I'm just unfazed. What also helps is that I let my nightmare and the creatures within it know that I am immortal. No matter what they do to me. In my dreams I am The Beginning and The End. I am all that will be there. They are there because of me. I'm essentially the only god that there is (I'm not religious but as far as my dreams are concerned, I am a god).

That throws off quite a lot of nightmares. The ones that persist, it's fine. They can test my immortality.

I've trained myself to have powers in the dream, but I rarely, fully know that it's a dream, so it doesn't really help when it's all psychological.

by logicprog

Can I just say that I agree with the other poster. I used to have a lot of nightmares. I didn't do it purposely, but I did figure out that lucid dreaming was the way to solve that issue.

I got interested in lucid dreaming for its own sake, and trained myself for it. I did all the common stuff in the guides, and eventually I had a habit of many times a day rubbing the back of my hand or something else tactile and asking myself if I was dreaming. After quite some time it did start to actually work in my dreams. I would frequently become "aware" in my dream and realise I was dreaming, and in my dream I would dream I would have control, but once I woke up it didn't even really feel like I had full control. It was not the experience I had been expecting, where everything becomes clearer, you can literally consciously control the dream. It was more like dreaming that I knew I was dreaming, and then controlling the dream, but I could never quite control it to the full extent I wanted to. No matter how much I practiced, this is all I achieved.

However, it wasn't nothing. It did let me start to realise I was dreaming in nightmares, and immediately just change them and become "in control" to the point where I could push back on whatever the nightmare was about, dictate on my terms. It still wasn't full lucid/awake control, but it was enough that I become the power in the dream, not the subject of the nightmare.

I really encourage you to keep trying. It took a lot of repetition during the day for the habit to finally enter my dreams. A lot more than I expected. But it did eventually work, to the extent I mentioned.

It's incredible when it finally clicks.

Arguably the best thing you can do is simply keep a dream journal (aside from deliberately waking up in the middle of the night and falling asleep with a clear intention - but that is more invasive in one's schedule and can also trigger nightmares).

by LawrenceKerr

You're right, I forgot to mention this. The dream journal was also a big part.

You can train for that. There are enough guides on the internet how to do it

So funny to see the recommendation here (track bedtime/wake-time, compute your average cycle length, predict the next bedtime from it, and don't deviate in either direction) be similar to how spaced repetition is typically sold to people: high expectations from users, no affordances for flexibility. These kinds of systems are just not realistic unless you are willing to be a loner that can never deviate from their routine.

I do agree that caffeine, alcohol, nicotine, sleeping pills, and (as much as we can) alarm clocks are all things to stay away from.

Is the author suggesting people to have to live with going through a phase of being nocturnal? In the free running algorithm, we're supposed to sleep 15 minutes later each day until we're falling asleep at like 9AM?

That's just incompatible with modern life right?

I once tried an extreme version of this. I became single and I already didn't have a fixed work schedule, so other than societal convention there was no reason for me to adhere to any regular day-night cycle.

So I tried sleeping when I was really tired, waking up without an alarm, eating when I was hungry, etc. I ignored watches, daylight and society. For context, my internal days have always been much longer than 24 hours, often finding myself going to sleep at sunrise; so I thought this was gonna be great, not having to spend an hour awake in bed.

It was horrible. And I mean HORRIBLE. I became a zombie, even though I was sleeping more than ever. I felt deeply depressed within two days. I lost all concept of the passage of time, and could never tell how long ago something had happened. I couldn't think properly or comunicate with other people. It affected me physically too, my weight, my stomach.

The experiment didn't last long. But I couldn't tell you how long.

I believe Mathew Walker writes in 'Why we sleep' that people's natural circadian cycle varies but on average is 24h and 15 minutes. But yeah sounds pretty inconvenient for most people.

by veritat14

4/15/2026 at 11:26:32 AM

That part didn't make any sense to me either. Yes, the natural circadian cycle in a vacuum is slightly over 24 hours, but exposure to light keeps it synced to the normal 24-hour day. If you free run sleep your cycle should stay locked to 24 hours, just like it has always been with our ancestors who lived without artificial light.

I am running a three-person team across three timezones has taught me that the hardest part isn't writing code at odd hours, it's the context-switching cost of partial sleep. You don't feel tired, you just feel slightly wrong all day. Decisions that should take 5 minutes take 30. The mental stability point rings true. When the product direction feels uncertain, sleep gets worse. When sleep gets worse, product decisions get fuzzier. Haven't fully solved this one.

Who else constantly pushes their sleep time by 1-2 hours a day, and likes 9-10 hours of sleep?

Also, these days it's nearly impossible to stay awake watching a show for more than 10-15 minutes while lying down in bed before a powerful wave of sleep knocks me out, which can be annoying when I want to watch a show.

I see a lot of people that smoke marijuana being off balance psychologically and I believe it’s because weed inhabits R.E.M. and they smoke it to go to sleep which creates a viscous cycle.

Unfortunately not in my case. I wouldn't be surprised if hangovers are worse if you're fit.

But what I've found is that forcing a run when hung over does help me move past it. Maybe it helps expel the metabolites from my body.

Best bullshit and industry cutting phrase for better sleep: Follow the sun. Follow the sun for a fixed reference point for when to wake up, and for when to sleep, and guard yourself from artificial lights like it's your professional job. Bryan Johnson says to treat sleep like a professional job, and I take it further: break the standard industrial-factory based paradigm around sleep, work and life and say no to the clock based wellbeing-adversarial system.

edit: hours and minutes cannot replace our natural light-based circadian rhythm that evolved for millions of years entraining our hormones and energy cycles around the sun's light.

I haven't had a chance to read the entire article, but I can already tell that much of how the author viewed sleep in 2012 is not inline with current understandings in sleep science, though much of the wearable and sleep industry still promote this outdated view.

Disclosure: I am the co-founder & CEO of neurotech/sleeptech company https://affectablesleep.com

The post talks about "sleep deprivation" which most people, and most studies, view as reduced sleep time.

The latest research shows that sleep regularity is a better predictor of health (via morbidity) than sleep duration, even when sleep duration is taken into account. This is on our blog with links to research [1]

I have a few issues with the "sleep more" concept, and I often say that you wouldn't measure your diet based on how much time you spend chewing, so why do we think this is a good measure for sleep. The methodology for measuring sleep, particularly deep sleep, was defined in 1968 by the sleeping pattern 28 college aged men and 5 college aged women [2].

We are able to show that decreasing the Neural Function of Sleep, the vital processes of the brain that make sleep restorative, and specifically slow-wave activity, reduces the effectiveness of sleep without altering sleep time. We can also enhance the Neural Function of Sleep to improve health outcomes measured by memory, HRV, cortisol, immune function, and more [3] links to research.

This isn't just limited to a bunch of lab studies. As we age, the Neural Function of Sleep naturally declines, and this decline is linked to age related metabolic health, cardiac health, and of course neurological diseases and particularly dementia and Alzhiemer's. Overly focusing on "just get more sleep time" doesn't solve the problem.

To further the problem, people often blame sleep for their tiredness, when they have poor diet, don't exercise, and/or poor mental health (stress, burnout, depression, etc). You can complain all you want about the gas mileage on your car and try tuning your engine, etc, but if you've got flat tires, you're not going anywhere.

Our work in neurotech and specifically sleep is focused on some of these issues, though I think the more important thing is for people to

1) Understand what sleep schedule works for YOU and focus on consistency and regularity. 2) If you're "tired" ask yourself if you are "tired" or "lethargic" is sleep really to blame? Or could there be other things that are impacting how you feel, or impacting how well you are sleeping.

I equate what we know about sleep and the brain today as similar to what we knew about diet and exercise in the 70s. We knew it was important but we really didn't understand how it worked. What we will learn in the next decade will upend our current understanding and have a significant impact on health and longevity.
