If you are not having proper sleep, regularly, wake up then! Something's wrong going on inside your body and you should know what it is. A majority of the population shows one or the other kind of sleeping disorders like, sleep-associated breathing disorders such as sleep apnea, sleep- associated seizures, Parasomnias such as sleepwalking, narcolepsy i.e. sudden and uncontrollable episodes of deep sleep, insomnia i.e. chronic sleeplessness etc. Sleep Apnea Syndrome refers to transient cessation of respiration during sleep. The most common kind of sleep apnea is called Obstructive Sleep Apnea Syndrome (OSA) which is defined as the cessation of airflow during sleep preventing air from entering the lungs caused by an obstruction. It is a potentially life-threatening condition that requires immediate medical attention. The risks of undiagnosed obstructive sleep apnea include heart attacks, strokes, impotence, irregular heartbeat, high blood pressure and heart disease. In addition, obstructive sleep apnea causes daytime sleepiness that can result in accidents, lost productivity and interpersonal relationship problems. There is a sleep test, called polysomnography that is usually done to diagnose sleep apnea. Polysomnography is a study of sleep cycles and behavior, usually done all night long in a sleep center, which involves observing a person at sleep while continuously charting brain waves, muscle activity, breathing, eye movements, and heart rhythms. Many labs offer home based polysomnography or sleep tests in which a sleep technologist hooks the patient up with the electrodes and instructs him on how to record his sleep with a computerized polysomnograph. These are painless tests that are usually covered by insurance.
