Insomnia is a symptom that may be caused by many conditions. Some of them are psychological (chronic dpresion or temporary stress), environmental (noise) or physiological (chronic breathing disorder or temporary pain). Another cause of insomnia is the use or overuse of sleeping pills.
Cannot Sleep At The Proper Time:
When the regualr waking and sleeping pattern is disrupted, some people find it difficult to resume a sleep wake schedule that fits their needs. This may be caused by shift work or other changes in schedule. Some complaints of insomnia or daytime sleepiness may be due to changes in the waking rhythm.
Narcolepsy:
People who are too sleepy during the day and feel muscular weakness when they are angry, surprised or amused may have narcolepsy. Sometimes narcoleptics experience terrifying dreams or hallucinations just as they fall asleep. Narcolepsy often emerges in young adulthood and is a life-long medical disorder.
Sleep Apnea And Snoring:
Snoring is not always just a normal annoying occurnace. if light, it may be trivial. However, heavy snoring may be a symptom of a serious sleep disorder called sleep apnea. People with sleep apnea stop breathing many times during sleep. These pauses last 10-90 seconds and can happen 100's of times a night. The symptoms of sleep apnea can include heavy snoring, high blood pressure and excessive daytime sleepiness.
Oxygenation Problems:
When people have chronic lung problems their symptoms often worsen during sleep. Complete evaluation of such respiratory diseases can require measurements of blood oxygen levels during sleep.
Nocturnal Myclonus:
People who have periodic leg movements during sleep may not get the proper rest and feel they have either insomnia or excessive sleepiness.
Nightmares And Night Terrors:
Nightmares are frightening dream experiences that can be recalled later. They can occur at any age. The causes of nightmares and night terrors is unknown.
Bedwetting, Sleepwalking and Sleeptalking:
These disorders are common in childhood. bedwetting is the most common, and in most cases its cause is unknown. Sleepwalking is also common in childhood and can be dangerous. Sleeptalking is usually incomprehensible and is rarely of any significance. The most important thing it to determine whether the troublesome behaviour is benign or a sign of a sleep -related epileptic seizure.
