Document Summary

Generally have 24/25 hour natural cycle; naturally fall into cycle even without seeing sun. Don"t know why we evolved into this cycle or why certain ages sleep different amounts. Restoration theories: during day you use energy and restore overnight. Different people need different amounts of sleep. Everyone needs some sleep or you die. Non-somniacs: only need to sleep 1-2 hours a night. Gardner stayed up for days to see how it affected him- no major issues after 12 days awake. No need to make up for all sleep missed; didn"t need to sleep 36 extra hours. Different species need different amounts of sleep. Bats and possums sleep 20 hours a night, horses sleep 2 hours a night. Adaptation theory-- sleep keeps us out of trouble; prey aren"t out in dark in order to stay safe so they end up sleeping more. Found brain waves change during night- go through stages.
