Sleep Disorders and Its Causes

Sleep disorders are disturbances of a person’s sleep cycle or the quality of sleep. Based on statistics, approximately 40 million Americans are believed to suffer from chronic sleep disorders, with millions more affected on an occasional manner. Doctors have defined more than 70 different types of sleep disorders.



Below are some of the most common sleep disorders and its definition.

Insomnia – it is the sense of poor quality sleep, including the inability to fall asleep or stay asleep. Since people differ in their required amount of sleep, there are no fixed standard that define insomnia. Insomnia is very common among Americans and in fact, it occurs in 30 percent t 50 percent of the general population. Nearly 10 percent of the population may suffer from chronic (long standing) insomnia.

Sleep apnea – it is characterized by a reduction or pause of breathing during sleep. Central Sleep apnea occurs when the brain failed to send signal to the muscles to breath. As a result of which, no muscular effort to take a breath occurs.

Moreover, in obstructive sleep apnea, the brain sends the signal to the muscles but although the muscles make an effort to take a breath, the process becomes unsuccessful because of the airway that becomes obstructed and prevents an adequate flow of air.  Meanwhile, in mixed sleep apnea, it is when both central sleep apnea and obstructive sleep apnea take place.

Restless leg syndrome – it is also referred to as nocturnal myoclonus. It is characterized by uncomfortable sensations in the legs and an uncontrollable desire to move the legs. The abnormal sensation commonly occurs in the lower legs shortly after going to bed and during the early stages of sleep, these series of leg movement often last up to an hour. The abnormal sensations brought by the RLS are quite inconsistent. Sensations are in fact described as crawling, creeping, pulling, drawing, tingling, pins and needles or prickly discomfort. However, cramping is not included in its character.

Narcolepsy – it is a disease of the central nervous system that eventually resulted uniformly in excessive daytime sleepiness. The disease is characterized by loss of muscle tone called cataplexy, distorted perceptions called hypnagogic hallucination and the inability to move ot talk called sleep paralysis. Other symptoms of narcolepsy include disturbed sleep and automatic behaviors. Unfortunately, the affected person carries out certain actions without their consciousness. All of the said symptoms of the disease may be present in various combinations and degrees of severity.

Some sleep disorders can be treated with natural sleep remedies. However, in severe cases, it is strongly recommended to seek medical attention from professionals to give you the right prescription.
