Sleep apnoea is the condition where breathing temporary stops during sleep. Apnoea is a medical term which means the absence of normal breathing. The condition occurs because of an involuntary relaxation of the muscles of the pharyngeal walls.
People who suffer from sleep apnoea usually snore, snort, or gasp in their sleep. The condition has harmful effects on the quality of sleep and overall health. Because of the repetitive episodes of apnoea, the person would often feel fatigued and tired throughout the day.
