Our brains are wired to recognize processes and register all our surroundings and process our thoughts, feelings and reactions all through the day. This cognitive function of the brain slows down when one falls asleep. Sleep is considered as a state where awareness and rapid movement is reduced.
There are two known stages of sleep, first there is the non-rapid eye movement when you’re slowly falling asleep and your brain is relaxing, then the rapid eye movement where one transitions into deep sleep. At this point the brain uses less energy hence your heart rate and body temperature falls.
The body needs this sleeping period in order to recharge and resume full brain activity after the rest making sleeping a crucial part of your daily functions.
