The restoration theory of sleep is one of the oldest theories on restoration. Through natural selection, this behavioral strategy presumably evolved to become what we now recognize as sleep.A simple counter-argument to this theory is that it is always safer to remain conscious in order to be able to react to an emergency (even if lying still in the dark at night). It goes onto suggest that animals who were able to stay still and quiet during these periods of vulnerability had an advantage over animals that stayed active.

There are four prevailing theories: the inactivity theory, the energy conservation theory, the restorative theory, and the brain plasticity theory.. One thing is certain: not getting enough sleep can lead to disastrous health outcomes, from a weakened immune system to depression. 437:1264-1271.

Inactive Theory Of . Certain substances, such as caffeine, alcohol, and nicotine, should not be part of a nightly routine. A sleep environment comprises several factors, including temperature, sound, and light. The electrophysiological and thermoregulatory continuum of slow wave sleep, circadian torpor and hibernation substantiates a primordial link between sleep and energy conservation. Additionally, just one night of sleep deprivation can lead to decreased mental performance, though these effects improve after recovering lost sleep time. Non-REM sleep is characterized by the following except: It arrives an hour and a half after you go to bed. In this theory, it is stated that sleep promotes body synthesis and repair.
