What is Sleep?

Sleep is a state of unconsciousness of mind where the very low electrical activity of the brain occurs and when sensory responsiveness becomes very less. Sleep is a kind of behaviour whose presence, quality, intensity, and activities vary from species to species along their lifespan. Every individual or animal uses sleep to maximize their energy by decreasing the body and brain’s energy consumption, releasing some hormones, and to conduct varieties of cellular processes to recover or we can say the recuperative processes.

Melatonin is a hormone that is named the hormone of darkness and is responsible for the sleep that is secreted by the pineal gland and lack of sleep affects the melatonin. Dreams that we see during sleep result in the release of norepinephrine.
