so we sleep in cycles, usually a one full sleep cycle is about 90min. it starts with light sleep, and goes into deep sleep, then back to light sleep, repeat. deeper sleep begins around ~30min in.

if you wake up from light sleep you’ll feel more refreshed

if you wake up in the middle of deep sleep, you’ll need to do all that body booting up when already awake, and it certainly doesn’t feel refreshing

(that’s why a 15min nap can breathe new life into you, but a 40min nap will leave you more tired)

it’s best to aim your sleeping schedule to include sleep in the increments of around 90min, proper night of sleep should have you go through 4-6 cycles (6h, 7,5h, or 9h).

the 90min is just an average though, listen to your body and see how things work for you. for me personally, around 7h or 7,5h works perfectly

we must be living in different civilisations then. all i’m hearing is “climate crisis faster than expected”

i mean… i hope good things will happen, but yeah i don’t expect them to. especially when we look at the climate crisis, we’re probably one of the last generations that’ll remember the world when it was relatively normal

i just hope i die before the whole planet is forced to ration drinking water
