Snoring is the vibration of respiratory structures and the resulting sound due to obstructed air movement during breathing while sleeping. In some cases, the sound may be soft, but in other cases, it can be loud and unpleasant. Snoring during sleep may be a sign, or first alarm, of obstructive sleep apnea (OSA). Researchers say that snoring is a factor of sleep deprivation. ==Signs and symptoms== Snoring is known to cause sleep deprivation to snorers and those around them, as well as daytime drowsiness, irritability, lack of focus and decreased libido. It has also been suggested that it can cause significant psychological and social damage to sufferers. Multiple studies reveal a positive correlation between loud snoring and risk of heart attack (about +34% chance) and stroke (about +67% chance). Though snoring is often considered a minor affliction, snorers can sometimes suffer severe impairment of lifestyle. The between-subjects trial by Armstrong et al. discovered a statistically significant improvement in marital relations after snoring was surgically corrected. This was confirmed by evidence from Gall et al., Cartwright and Knight and Fitzpatrick et al. New studies associate loud "snoring" with the development of carotid artery atherosclerosis. Amatoury et al. demonstrated that snoring vibrations are transmitted to the carotid artery, identifying a possible mechanism for snoring-associated carotid artery damage and atherosclerotic plaque development. These researchers also found amplification of the snoring energy within the carotid lumen at certain frequencies, adding to this scenario. Vibration of the carotid artery with snoring also lends itself as a potential mechanism for atherosclerotic plaque rupture and consequently ischemic stroke.〔 Researchers also hypothesize that loud snoring could create turbulence in carotid artery blood flow. Generally speaking, increased turbulence irritates blood cells and has previously been implicated as a cause of atherosclerosis. A U.S. study estimates that roughly one in every 15 Americans is affected by at least a moderate degree of sleep apnea. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「snoring」の詳細全文を読む スポンサード リンク
