The biological function of sleep allows us to recover from physical, intellectual or emotional fatigue. It allows the brain to assimilate, classify, remember and see more clearly the information accumulated during the day. Sleep allows the establishment and development of nerve circuits in the fetus and during the first months of the baby’s life. It also promotes the release of growth hormones, which explains why it is bad to deprive a child or adolescent of sleep. Sleep also contributes to healing, relieves stress, and allows for release and rest. In short, the health benefits of sleep are numerous.
The heart rests and the brain is cleaned
Sleep helps strengthen the immune system and make it more effective against seasonal viruses and surrounding microbes. It allows the heart to slow down and save itself and promotes the cleansing of the brain, which uses this rest time to eliminate cellular waste produced by neural activity when it wakes up.
A team from the University of Rochester explained in 2013 in the journal Science that “the brain has two different functional states. It is either awake and alert or inactive and in a clearing mode. Because it has limited energy resources, it is forced to switch between the two. The brain pumps the cerebrospinal fluid through the tissues and cleans them during the night. The waste products are transported through the bloodstream to the liver, where they are excreted.
