what are the 5 functions of sleeping
energy conservation theory (decrease in metabolism during sleep)

explain the energy conservation theory for sleep
decrease in metabolism during sleep
=allows us to conserve energy for wakefulness
explain the inactive theory for sleep
more for animals
=going to sleep when predators are out
explain the restoration theory for sleep
replisninsh brain stores such as glycogen

n1
true or false: transition to light sleep period (n1) takes up large portion of our nigth
false, only 2-5% (only really active when trying to fall asleep or after waking up during night)
