obstructive sleep apnoea syndrome

obstructive sleep apnoea syndrome (OSAS)

The periodic cessation of breathing or a substantial reduction in breathing caused by temporary blockage of the airway by the tongue or respiratory collapse of the lower throat during sleep. After 10–90 seconds lack of oxygen alerts the brain and the person wakes. This may happen up to 400 times in one night and may damage health or even cause a stroke. A major factor is obesity. OSAS causes serious day-time somnolence and loss of performance and may make driving dangerous.
