Why we need sleep

Well, this will anwser your question

Why people sleep?

We need about 10-11 hours of sleep so our brains can become rested and ready for the next day. If you dont get any sleep for your brain, you will be so tired in the morning. The brain needs about the maximam of about 6-5 hours of sleep. If you get 1 hour of sleep, you will be super tired and not think at all.

Some pictures I found on Source 2:

Frequtly asked questions

I hear people say all the time "Why do people sleep?" I wondered that also, so I decided to reasearch about why humans sleep but I never got time to do it but I did now and this is what I got from the sources and pictures.
