- Deliberate relaxation - I found the muscle relaxation technique incredibly valuable ( https://www.healthline.com/health/healthy-sleep/fall-asleep-fast )
- Sleep in a cold, dark room
- Limited phone time - mindless scrolling is fine if it helps me relax, but not if it amps me up
What I haven't found matters for me: - Strenuous exercise - I've found that training late at night (I compete in powerlifting) and going to bed immediately after leads to very deep, restful sleep
- Caffeine timing - to an extent timing matters, but daily amount is by far the biggest driver for sleep quality
- Meditation - it affected sleep adversely and even though very calm and level, I felt substantially more awake after meditation
Not only does this assume everyone in the thread is American, but also completely disregards the sovereignty and historic significance of many Eastern European countries.
