They say you need complete sleep cycles to get proper rest, which take about an hour and a half. Anything less than that and you're interrupting a cycle which can do more harm than good.
>you're better off just sleeping until you wake up.

It's best somewhere around 15 minutes. It shuold not exceed 20 or you're just finna fall into deep sleep and then you should just go for the entire sleep cycle >>16480845

You can't catch up on actual sleep with naps but you can trigger a little hormonal rebound with a 15 minute nap, making you feel a bit better.

Works for me when I’m recovering from jet lag. I lay down, fall asleep, hit rem and a dream, and wake up automatically. 15 - 20 minutes and I feel completely refreshed.

I don’t really feel the need to do it when I’m sleeping normally though.

Same here, naps are total bullshit. Just get enough sleep at night and if you're tired during the day hammer through it with caffeine. If you sleep during the day because you didn't sleep the night before you'll wind up staying up even later the next night and the basic problem just gets worse.

if you have high blood sugar or have recently eaten it is a bad idea
if you get tired from sugar it's a bad sign
if you are fasting and able to take a nap, go for it
