sleep

positive anticipation to the next day’s event -> better sleep quality

consistency

getting same amount of sleep every day

say, 5 hour everyday

consistency > duration

consistency of sleep duration make sleep quality better, and the effect would outweight the duration of sleep itself

implication: sleep booster don’t really work

after sleep 5 hour each day for a week, a 5 hour sleep would give you better wake up clarity of mind, than a sudden 8 hour “sleep booster”

getting your leg elevated, i.e. same hight as your hip, would start a process of clearing some stuff out of your system.

The above 3 tips(positive anticipation, consistency of duration, legs elevated) are from a youtube video. I forgot which.
