The Science of Sleep
Internal Clocks Our body creates a hormone called melatonin when the evening rolls in. Melatonin makes us feel drowsy when it is dark outside. The process of creating melatonin begins inside of the retina part of your eye and when light hits the retina, a message is sent to the suprachiasmatic nucleus in your brain. In this area of the brain there is a message that tells us when to feel tired or awake. This happens by messages being sent to the rest of the brain that at control different hormones and body temperature. During the day, melatonin is not produced in the body. However, at night the body begins to produce it. A lack of light also produces this hormone.

Teenagers produce melatonin three hours later than in the sleep cycle than adults and children. This means for teenagers, a late sleep time combined with an early wakening makes it hard for teens to have the energy they need. By the time teenagers are supposed to be at school, they are still trying to lose the melatonin. This causes miserable mornings where it’s hard to pay attention in class and function properly. According to many scientists, teenagers are supposed to get 8-9 hours of sleep. Because of the late melatonin production, many teens will find difficulty falling asleep resulting in a loss in sleep even if they “go to bed”
