For real though, it’s habit. They didn’t naturally start that way. They just kept doing it that the body eventually “learned” to set their sleeping rhythm to that schedule.
Everyone has a different natural circadian. Sure you can force yourself to go to bed at a time when your body doesn’t want to and try to “train” yourself, but really you’ll just be tired all the time. Your body does not learn a new time, you just get used to being tired.
I guess everyone is different. I used to wake up at 2am for gym + morning shifts. Eventually I woke up before my alarm consistently. I didn’t feel tired.
These days, I wake up at 7am most days and feel just like I did when I woke up at 2am.
