Side Effects of a Lack of Sleep
Do you suffer from sleep deprivation? Most teenagers need 8-12 hours of sleep. Lack of sleep can cause delayed reactions or even learning disorders. Prolonged loss of sleep occurs for physical and mental reasons and has harmful physical and mental effects to the human body.
Prolonged sleep is caused by many different functions of the body. An important cause of prolonged sleep is a teenagers biological phase-delay or a tendency to fall asleep and wake up at different times. Changes that occur at puberty in the internal body clock governing their circadian biological rhythms can cause them to sleep irregularly(Johnson, 3).
Another good reasons why teenagers do not get enough sleep is because they simply do not make time for it. Some schoolwork, sports, jobs, girlfriends or boyfriends may take up most of a teenagers time or cause them to have stressful sleep(Johnson 3).
Sleep deprivation can cause slow reactions of time. It may also cause headaches and nightmares more frequently. The mind will fall asleep if it cannot get enough sleep causing it to not function properly. Some side symptoms of chronic lack of sleep are feeling fatigue or depression as body becomes drained (Haynes).

If you continue to have prolonged lack of sleep your immune systems will begin to break down and become unstable to fight diseases (Haynes). To show how this is caused the researcher has done a study on how much sleep he/she got and how they felt that day.
