SLEEP DISORDERS 2
Humans spend about a third of their lives sleeping. A good night's sleep is essential to the
overall well-being of a person, both physically and psychologically. Sleep happens in the forms of
four stages leading to the rapid eye movement stage of sleep, where dreaming takes place and brain
activity is astoundingly similar to that of a fully awake person. The way you feel while awake
depends, to some extent, on how much and the quality of your sleep. Sleep helps the brain prepare
for the day; it clears out all the unnecessary information, creating new pathways for learning and
remembering information. It plays a major role in growth and development, and regulating
hormones like ghrelin and insulin. But not all people are able to get a proper rest. Some suffer from

drive their car or something as equally disastrous. Sleepwalking happens...
