Sleep Disorders: Rapid Eye Movement

"Sleep disturbance seems to be a worldwide epidemic affecting 45% of the world's population" (Noor, et al n.p.). This will not affect 55% of the world's population. More than 70 million people in our country are suffering from sleep disorders, but most of them suffer from sleep disorders, but most of them do not recognize the impact on their daily lives (Wells, Vaughn 234). This number is increasing as many people do not know the effects of sleep disturbance. The main known sleeping disorders are rapid eye movement (REM), insomnia and obstructive sleep apnea (OSA).

Narcolepsy is a disease condition in which one in about 2,000 people in the United States develops. This disease is a sleep disorder involving irregular patterns in rapid eye movement (REM) sleep and significant disorder of normal sleep / wake cycles. The etiology of narcolepsy is not fully understood, but current research suggests a combination of genetic and environmental factors that affect the immune system.

It is now believed that there are three different human presence states that are waking up, sleeping not as eye movement (NREM) and sleeping rapidly with eye movement (REM). A comprehensive discussion on arousal is beyond the scope of this article, but this article and other articles explain the influence of sleep disturbance on arousal state. Please note that in the following discussion, many factors may affect sleep. You can consider "normal sleep" mode, but this is generalization. Neonatal sleep is very different from adult sleep. When you are a child, sleep changes dramatically. Therefore, normal sleep in adolescence and the need for that sleep are different from sleeping in children and sleeping in adults. Even adults sleep during age change. However, in this article, ordinary young people 's usual sleep is common. In the future article, I will explain the difference of the times.

There are two different states of normal sleep: non-rapid eye movement (NREM) and rapid eye movement (REM) sleep. NREM sleep can be divided into 4 stages. During REM sleep, rapid eye movements occur, breathing becomes irregular, blood pressure rises, and muscle tension is lost (paralysis). However, the brain is very active and the electrical activity recorded by EEG in the brain during REM sleep is similar to the electrical activity recorded during awakening. REM sleep is usually related to dreaming. REM sleep accounts for 20% -25% of sleep
