What is sleep disorder?
This is a disorder which affects the brain and body, resulting in insomnia, poor sleep quality and disrupted sleep patterns. This disorder may affect both males and females, but most commonly occurs in males and females between the ages of 30 and 45 years old. Sleep disorders may include insomnia, sleepwalking, nightmares, poor daytime alertness, problems with memory, and a general lack of energy.
There are different types of sleep disorders. Sleep-disordered breathing is the most common form of sleep disorder. Sleepwalking is usually classified as a form of insomnia, although there are cases of sleepwalking without sleep disorder, and cases of both sleepwalking and insomnia. Insomnia usually consists of frequent waking up and falling asleep with no apparent reason. Nightmares occur when people have vivid or disturbing dreams in which they imagine being hurt or otherwise threatened. Problems with memory may occur during REM sleep, but most people report that this is less common than nightmares. Most people also report a general feeling of being out of their normal routine.
Sleep deprivation is more common than many people realize. There are many people who feel like they've fallen asleep after only 1 or 2 hours of sleep.
