Next, I will discuss sleep. There are many sleep myths that circulate, including that sleepiness can be dissipated (not true). Sleep can be defined as a reversible sensory shutdown, in which one is no longer aware of his or her environment. Sleep is extremely beneficial; it rests the body and restores the brain, organizes and integrates information and memories. The brain is surprisingly as or more active during sleep than it is when awake.

Sleep can be divided into REM and non-REM sleep. REM, or rapid eye movement, is a phase in which the brain is very active, the body is paralyzed, and vivid dreaming occurs. Non-REM sleep consists of slow, rolling eye movements, non-paralyzed body, and the brain is less active than in REM.

Circadian rhythms dictate your body’s internal clock and are controlled by the SCN in the hypothalamus, allowing got certain biological processes to happen at the same time each day.

There are two important hormones that are associated with sleep: cortisol and melatonin. Cortisol, secreted by the adrenal glands, beings about wakefulness and energy to begin the day, while melatonin, secreted by the pineal gland, causes sleepiness.

Teens actually need about 9-10 hours of sleep of night, and when this need is not met, a sleep debt builds up, which does not go away until the sleep is made up. This can be spotted if you feel yourself becoming drowsy throughout the day. Drowsy driving, for example, is extremely dangerous and can be fatal.

Napping is a very effective way of reducing sleep debt. Short naps are optimal for refreshing yourself; however, naps are not the solution to extreme sleep debt. Sleep deprivation can have severe consequences, like impaired performance, mood, immunity, and lack of alertness.

Lack of sleep is an issue I have dealt with both junior and senior year. I would fall asleep in class on a daily basis and I wasn’t absorbing information well at home. It was extremely detrimental to my learning. However, for me, naps were extremely useful for helping fix my sleep debt, and I have learned better time management. Scheduling your activities in the day help to keep you on track, and you will be able to get your 9-10 hours of sleep.
