“We spend about one third of our life sleeping. Sleep is defined as the suspension of consciousness during which the powers of the body are restored (ThinkQuest, 2003). The brain is not at rest during sleep as popularly thought, but is extremely active and it is the brain that tells us when it is time to sleep. Sensations of light taken in from the retina are transferred through the nerves to an area of the brain determines the amount of light exposure and adjusts the body accordingly. The exact purpose of sleep remains a mystery, but researchers speculate that during certain stages of sleep, the brain is testing, strengthening, or somehow improving our neurons.”
