Sleep Definitions

The description of the definition of sleep is considered important, given the understanding of the definition of something to limit the breadth and depth of learning objects. That following will describe some definitions of sleep based on various sources.

Turpin (1986) in Leahy & Kizilay (1998, p. 700) defines sleep as a state where the organism is regular, repetitive, and easy to come back (reversible) signed on by the state of relative quiet / without motion and increased the threshold of response to external stimuli . While Martini (2001) defines sleep as a state do not realize (unconciousness) but can be awakened with the appropriate sensory stimulation. There is also another opinion that defines sleep as a change in state of consciousness that occurs continuously and repeatedly to save energy and health (Potter & Perry, 1993, p. 1146). Meanwhile, Berger & Williams (1992, p. 1317) defines sleep as a physiological rhythm and normal complex, involving a change of state of consciousness of an individual who can be awakened by an appropriate stimulus. The opinions put forward almost as well in Guyton (1996, p.. 945) that defines sleep as a subconscious state where the person can be aroused by sensory stimuli or by granting other stimuli. Meanwhile, according to Kozier (1995, p. 953) definition of sleep has experienced evolution. Historically, sleep is considered as an unconscious state (state of unconsciousness). Meanwhile, according to the latest concepts, sleep is defined as a conscious state (state of consciousness) in which the perceptions and reactions of individuals to environmental decline.
