Many of us prioritize work, social activities, and entertainment over the amount and quality of sleep we get each night. However, sleep is essential for physical and mental health, as well as cognitive performance.

What is Sleep?

Sleep is a natural state of rest that occurs in periodic cycles. It is characterized by a decreased level of consciousness and sensory activity, reduced muscle tone, and a slower heart rate and breathing rate. The sleep cycle consists of several stages, each with distinct physiological and neural patterns. The two primary categories of sleep are non-rapid eye movement sleep and rapid eye movement sleep. Sleep is further divided into three stages, each with a progressively deeper level of sleep.
