Recent findings suggest that sleep plays a housekeeping role that removes toxins in your brain that build up while you are awake.
What are the two major theories about the functions of sleep?
Several prominent theories have explored the brain and attempt to identify a purpose for why we sleep, which includes the Inactivity theory, Energy conservation theory, Restoration theory, and the Brain plasticity theory.

What is the primary purpose of sleep?
