    Restorative Theory Of Sleep

    There are many reasons why we need to sleep but here are three main theories. The first is the Restorative theory, “According to the restorative theory, sleep allows the body, including the brain, to rest and repair damaged tissue.” (Grison, Heatherton, Gazzaniga, 2017, pp. 93). This allows our bodies to get the proper recuperation it needs for a fresh day. The next theory is the circadian rhythm theory this theory states “Sleep keeps creatures quiet and inactive when the danger of attack is greatest -- usually when it is dark.” (Grison, Heatherton, Gazzaniga, 2017, pp. 93) Sleep not only is a way for us to recover but also a survival technique. This is the reason why big animals such as cows and deer get less sleep than a rabbit. The bigger the animal the greater chance of attack. The Last and final reason for why sleep is important is because of the consolidation theory. “Consolidation theory is that circuits wired together during the waking period are consolidated, or strengthened, during sleep.” (Grison, Heatherton, Gazzaniga, 2017, pp. 93). All three of these theories are important reasons to why we need…
