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 sa…

I think one of the underrated things that Bryan does is he regularly emphasises how central sleep needs to be in your health. I haven't heard that consistant message drilled in by anyone else and it helped me realise how a lot of the things i found difficult to recruit energy/discipline/motivation were related to the low priority I placed on sleep.

Peter Attia is also big on sleep. But it sits alongside 3-4 other things of similar importance in his messaging.

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 c…

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 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…

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 girl…

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.

There are bars everywhere

There are also gambling machines everywhere around me yet I don't know a single person who uses them. I looked up numbers for the USA and 2025 54% said they consume alcohol. So it's most people but millions don't.

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.

> 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.

Wake up without an alarm clock is surely beneficial regardless of when you go to sleep?

I try to explain this to my wife, my baby, and my dayjob but they refuse to listen.

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…

WatchPAT is what I used, there's a few different companies who will mail you one, then you sleep with it on your finger overnight, and a doc reviews the data

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 t…

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).
