About Sleep
Sleep is necessary for mammals and many other animals, in order to rejuvenate their bodies. During sleep consciousness is lost or reduced and we are less responsive to external activities. Most people need at least 8 hours of sleep per day in order to function at their highest level. Not getting enough sleep can increase the risks of cancer, heart disease, obesity and diabetes.
