ELI5, why is going to bed super late bad for you if you still get the same amount of sleep?

632 views

I’ve always wondered this, espeically over summer break or for those who work later but why is going to bed late bad for you if you still get the perfect amount of sleep?

For example, last night I wen’t to bed at like 1:30 AM and woke up at 10:30 am, which is 9 hours? So if I’m getting required sleep, how is it bad for me?

1. Cycadian rhythms are most effective when aligned with natural light (specifically low angle UV light that wakes you up and outs you to sleep due tovevolution)
2. It’s more about having the same sleep schedule so one or two late nights then swapping back to regular time is bad for your body.
