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.
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?
>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.
Difficulties navigating everyday life and my career pretty much, I am intelligent and capable but the struggle to manage everything was becoming too much.
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.
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.
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.
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.
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.
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?
this mirrors my experience too. I’ll just add that some times taking a complete break from work is necessary to find the mental clarity to reach the state where learning, stability and happiness are possible.
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! :)
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.
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.
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.
> There is only one formula for healthy and refreshing sleep: Go to sleep only when you are very tired. Not earlier. Not later. Wake up naturally without an alarm clock.
This is very easy to say when you're not suffering from insomnia and other sleep disorders.
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.
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.
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?
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'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 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'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.

If I did that I would go to bed a 5 in the morning and wake up at 2pm, sir.
