“Sleep doesn’t serve one single purpose. It is a complex function and directly related to our health. The multiple functions benefit both our brains and our bodies. Every single brain process and every organ in the body is enhanced by sleep or damaged by the lack of sleep. Within the brain, sleep affects our ability to learn, memorize, and make decisions. It works as an emotional reset so that social and psychological challenges are met with level-headed logic. Sleep provides the opportunity to dream in a world where painful memories are dealt with and future creativity is inspired. While in a sleep state, the body’s immune system is at work to fight cancer, prevent infection, and ward off disease. Sleep balances insulin and circulating glucose to create a metabolic balance. Appetite, weight control, and gut health are all directly tied to adequate sleep levels.”
