You gotta get sun in the morning to start your day right, then get sun in the middle of the day (peak sun), and then get sun as its setting. This is important to tell your eyeballs and also brain when to be awake and when to start getting sleepy. It’s been nice spending a lot of time outside (as a street dude doing 1000 things in one day) lately, and I’m thinking in the winter I might start hitting the tanning beds in order to preserve my base layer of melanin.
It’s also good to go to sleep at the same time every night. If you go to sleep and wake up at the same time every night, it’ll really help a lot. Tough to do if you’re chilling, but life is often about tolerating contradictions.
Also, how about this new Drake called Circadian Rhythm?
