Sleep is defined as a state of unconsciousness from which a person can be aroused. In this state, the brain is relatively more responsive to internal stimuli than external stimuli. Coma is an unconscious state from which a person cannot be aroused. Sleep is essential for the normal, healthy functioning of the human body. It is a complicated physiological phenomenon that scientists do not fully understand. Historically, sleep was thought to be a passive state. However, sleep is now known to be a dynamic process and our brains are active during sleep. Sleep affects our physical and mental health and is essential for the normal functioning of all the systems of our body, including the immune system.
