Rejuvenating Sleep
Sleep is a naturally recurring state characterized by reduced or absent consciousness, relatively suspended sensory activity, and inactivity of nearly all voluntary muscles. It is distinguish-ed from quiet wakefulness by a decre-ased ability to react to stimuli, but it is more easily reversible than hibernation or coma. Sleep is a heightened anab-olic state, accentuating the growth and rejuvenation of the immune, nervous, skeletal and muscular systems. It is observed in all mammals, all birds, and many reptiles, amphibians, and fish.-Wikipeia
