That’s because this is in UK Biobank, a cohort of >500K Brits and collecting actually in such a large cohort is a miracle, let alone for multiple days. All thanks to the people who volunteered into the study. Would it be nice to have even more? Sure. But at that scale, patterns start to emerge.

I found the best way to ensure sleep regularity is by having a fixed wake-up time. If you don’t have one and you begin to set your alarm clock to early hours, the first weeks doing so will feel like hell. But eventually all will be worth it. The sleepiness during the day will disappear and, at night, your body will naturally want to get some rest early. Another strategy is to fill your day with deep work and exercise…

I think you have a key component in good sleep but there are 2 more imo. The first is that phones and light break our natural sleepiness triggers and the second is that we don't exercise our bodies enough because of our sedentary lifetstyle. I used to struggle with terrible insomnia and I still get bouts of it time to time but I've also found it's related to my laxing my 3 rules. If I have a good workout about 5x a w…

For people failing for a long time at fixed wake-up schedules or still feeling like shit after months of doing it: giving up is fine, and it frees you to explore what works for you. It might change depending on the seasons, and you might more or less sleep depending on what you're doing at that time. Waking up at the same damn hour everyday to deal with my kid's school was an utter pain for years, and I got in a bett…
