Things to consider: CO2, timing of exercise, timing of eating (What does "Eating < 7pm" mean?), bed cooling (ie, 8sleep, ooler etc)

I'll chime in here too. I gave up caffeine on a lark during lockdowns. Man, great decision. I've never slept better and my anxiety went way down too. I'd had no idea what that stimulant happened to be doing to my system. I had been tapering down my caffeine consumption too, but going cold turkey had a major difference for me. I'll caution that 3 days of pretty intense headaches were the cost, but for me, the benefits…
teas have caffeine?
Black tea and green tea, like Earl Gray or Matcha, yes they have caffeine.
Chamomile or tea of an other non-caffeinated plant boiled in water, no.

2pm might not be early enough. Depending on genetics the half life of caffeine in your system can vary by a lot. Even if you're in the normal range, a half life of 4-6 hours means that ~25% of the caffeine would still be in your system by midnight... If you're that worried about sleep quality, it's baffling you have not tried cutting out caffeine altogether
No caffeine after 10am here.

All decafs I tried tasted like ass. And I buy quality beans from the hipster roasters.
Maybe see if one of those roasters mentions the Swiss water process. IME it makes for quite good decaf (and I too have a hipster’s taste in coffee).
Wow, I had never heard of this before. The chemical process for decaf had always put me off before.

You may have just convinced me to switch to decaf...
I don't use any of them, but I've heard firsthand from some like the author complaining about inaccurate data from devices like the Apple Watch and Oura, some getting rid of them due to this. Since the OP continues to use them, am I to understand there is no better alternative that is comparable on the comfort/ease-of-use/cost-effectiveness axis with these devices? The idea of making health decisions based on bad dat…
Recently saw a sleep specialist who also gave this advice (amongst other things). It wont have an immediate impact, but give it a few weeks.

Also, if you think you might have sleep apnea, and frequently waking up during the night is indicative, then do try and get a sleep study done.

Myth.
has the historical evidence been reconsidered? i remember reading quotes from historical people who were all pretty clear that this is how they slept, and often implied they considered it not to be unusual.

> Coffee leads to dehydration. Drink several liters of water during the day and some people may be able to continue with morning coffee consumption. This is a myth. Coffee has water in it. Just drink enough water from all sources.
It’s a shame this is downvoted on HN of all places. I have seen various research that suggests both caffeine (in coffee & tea) and even alcohol (in lighter beers) do not dehydrate. I’ll stick with caffeine since that’s the topic. The primary study that spread the idea that caffeine dehydrates is from a 1928 study with a sample size of three men[0]. It may very well be that caffeine does dehydrate, but I have yet to s…
If you listen to Humberman Labs podcasts[1] at all, you'll know he is a big advocate for going outside and getting some direct sunlight in the mornings (including no sunglasses).

It's not a panacea, but at this point I think it should be considered as essential as showering, brushing teeth, etc.
