The night time is a dangerous time and it is hard to find food at night. Therefore our ansesters evolved the ability to shut down at night and conserve enery for the next day. In addition our brains can run at a higher output level if they have a recharging period each day. Bye, it's time for my nap.

Bright places usually mean daytime which means more people awake so more sounds you wake you up. Lots of second and third shift people sleep in the day time.

I always sleep in front of the TV, beach, etc. , wherever I'm tired.
