Sleep is a vital part of life. The many different functions of the body depend on sleep to reenergize and grow. Various types of sleep disorders and parasomnias can interfere with sleep, leaving one feeling sluggish and slow. Many people live with sleep disorders that are untreated or not diagnosed, while others suffer with these disorders, and are unable to get a good night’s sleep. Sleep disorders affect many people and they can be easily treated. Other types of sleep disorders can be grown out of, or lived with without effecting one’s life. However, it is important to treat severe disorders to prevent oneself from getting a lack of sleep.
The brain and body functions in a different manner during sleep then during the waking hours. During sleep, energy is replenished and energy saving organs repair themselves in the body. The brain moves new information to a more permanent memory, and the cerebral cortex shuts down during slow wave sleep(Brynie, 16). The frontal lobe is a part of the cerebral cortex and it is the brain’s most active region during waking hours. It also is the part of the brain that is is for reasoning and decision making. A night without sleep will impair performance of comprehension, concentration, creativity and problem solving. Sleep is extremely important for the body, and without it the body is unable to function properly. The body and brains roles during sleep are vital to repairing and restoring energy, creating memories, and reenergizing itself to function properly for another day’s work.
Sleep is especially important for fighting illnesses, and for children to grow and develop. From the ages five to seven years, children develop REM and non REM patters as adults. This is because they start school and sleep less on weekdays and more on weekends and vacations. Their sleep patterns decrease from 11 hours to 9.25 hours. (Brynie, 23) Nightmares and night terrors develop during these ages as well as sleepwalking and “bedtime resistance.” (Brynie, 23) In teens, time spent in slow wave sleep decreases and they wake more at night which then leaves them feeling sleepier during the day due to shifting hormones and social demands. Illnesses require more sleep because while fighting the infection, the brain triggers sleep centers, and the pituitary gland sends signals to step up the production of white blood cells that fight the viruses and other microorganisms. (Brynie, 20) Sleep is not only needed to reenergize the body, but it is also needed to help fight off sicknesses, and boost a child’s growth and development.
There are many stages of sleep in the sleep cycle. These stages begin at one and goes to five, five being REM sleep, or Rapid Eye Movement sleep. In stage one, the body experiences sudden muscle contractions, causing the sensation of falling and jumping awake. The big muscles relax and the eyes will continue to move, but the slightest disturbance can awake the sleeper. Stage two includes sleep spindles, which...
