Sleep is the regular state of natural rest observed in all mammals, birds, and fish. Sleep is not actually "unconsciousness," but rather, it is characterized by a reduction in voluntary body movement, decreased reaction to external stimuli, an increased rate of anabolism (the synthesis of cell structures), and a decreased rate of catabolism (the breakdown of cell structures). Therefore, since consciousness is literally the awareness of the surroundings, being asleep is just an altered state of consciousness, as opposed to being unconscious. It is heavily influenced by circadian rhythms and by hormonal and environmental factors. Sleep performs a restorative function for the brain and body as evidenced by the myriad symptoms of metabolic dysfunction that result when animals are deprived of sleep.

The body needs rest to repair itself and maintain a strong immune system. Sleeping is a normal activity, just like breathing.
