Everyone is different. Good sleep hygiene is going to sleep when tired (not at a set time) and waking up at the same time each day. Eventually you’ll wake up at the same time without an alarm clock. The key is to go to sleep when you’re tired, sometimes that 10pm sometimes it’s midnight. Caffeine, eating late, blue light will all impact when you’re naturally tired.
People run into problems because they use lay ins to make up the shortfall when really the lay in should be gained by going to sleep earlier the night before.
If you’re jumping out of bed when you wake then you’re waking up in-between sleep cycles, which is ideal.
yeah, that sucks
longer fasts are easy for me, after i get over the first 24h
but i have a hard time falling asleep after \~50h of fasting.
so i have to force my self through the hard part again and again if i want to get my normal amount of sleep
