  3. Restorative Theory • Opportunity for rejuvenation • muscle growth, tissue repair, protein synthesis, and growth hormone release occur mostly, or in some cases only, during sleep Why do we sleep? Energy Conservation Theory • To reduce energy expenditure • Metabolism is reduced during sleep Inactivity Theory • Evolutionary adaptation • Keep low profile during times of vulnerability

  4. What happens when we sleep? • Circadian Rhythms • Physical, mental, and behavioral that follow a 24 hour cycle-mostly corresponding to light and dark in the environment • Controlled by “biological clocks”-groups of nerves • Better understanding could lead to treatments for sleep disorders, jet lag and other health problems
