Sleep is the state of natural rest. It is characterized by a reduction in voluntary body movement, decreased reaction to external stimuli, an increased rate of anabolism and a decreased rate of catabolism. Studies of human sleep have established five well-defined stages, according to EEG recordings and polysomnography - 75-80% is Non REM sleep (has 4 stages) and REM sleep.
