WHAT CAUSES SLEEP APNEA?
The condition is caused when the muscles of your throat relax, the tongue falls backward and the upper airway becomes narrower, blocking the airflow while sleeping. This condition causes the lack of oxygen in blood and alerts the brain causing frequent but brief arousal from sleep in order to reinstate the normal breathing process. The breathing pauses lasts for 10 to 30 seconds and in severe cases it can last to one minute or more.
WHO IS AT RISK?
Although there is no specific age group for apnea, it usually starts at middle age and gets worse with time if not treated. Apnea and snoring may occur in overweight men and women. Children who have large tonsils and adenoids are also at risk.
