Sleep Is a Natural Loss of Consciousness

Sleep is a regularly recurring, natural loss of consciousness that many creatures experience. Is characterized by a special sleep posture and is often associated with dreaming. An average healthy adult will get about eight to nine hours of sleep per day when left on their own without pressures like keeping a work schedule. Scientists also discovered that there are patterns in how the cycles occur. There are about five or six cycles of non rim and rim sleep each night, each of which lasts for about 90 minutes. And our brain waves change as we go through different phases of sleep.
