There are various sleep disorders. The most common sleep disorder is insomnia. A person with insomnia has difficulty in one of the following areas of sleep: falling asleep, staying asleep all night, or not being able to go back to sleep after waking up. People with insomnia may feel lethargic and non-alert because it prevents them from achieving restful sleep. Possible causes of insomnia include physical illnesses, emotional problems such as stress, anxiety or depression, and substance abuse. Going to bed stressed and with worries and worries can also lead to insomnia. When you worry, your body becomes excited and this can disturb normal sleep. Additionally, thinking about having to sleep through the night can increase your anxiety level, making it harder to fall asleep. One remedy for insomnia is not to try to “force” sleep. One potential remedy for insomnia is to engage in cognitive-behavioral techniques that focus on changing problematic sleep habits. The next sleep disorder is narcolepsy. People with narcolepsy experience periods of intense daytime sleepiness and sudden bouts of sleep that can occur at any time of the day. These sleep attacks are called sleep attacks. “Sleep attacks” can last a few seconds or several minutes. Narcolepsy can significantly disrupt daily activities. People suffering from narcolepsy may fall asleep while working, talking, eating, etc. An episode of narcolepsy usually lasts about 15 minutes. In a typical sleep cycle, we initially enter NREM stages before entering REM sleep. For those who suffer from narcolepsy, REM sleep occurs almost immediately after an attack. In addition to daytime drowsiness, other symptoms may include terrifying hallucinations... middle of paper... remember parts of the dream. The cure for night terrors is that most children recover from the disorder by adolescence. Sleepwalking disorder may be characterized by walking or performing other activities while apparently still asleep. Sleepwalking disorder is more common in children than in adults. About 5% of children suffer from this disorder. The disorder originates during deep, dreamless sleep and causes walking or performing other elaborate actions while remaining asleep. Throughout the episode, the sleepwalker remains asleep while walking with his eyes wide open. Although people often do not suffer injuries while sleepwalking, accidents can occur. It is normal for the sleepwalker to remember nothing the next morning. It is not dangerous to wake a sleepwalker, although it is normal for the person to be disoriented or confused upon awakening.
