Sleep apnea is a serious sleep disturbance involving periodic airway collapse and reduced blood oxygen. Chronic sleep apnea is linked to premature death, cardiovascular disease and impaired sexual function. Continuous positive airway pressure (CPAP) keeps the airways opened during sleep and is an effective treatment for the disorder. Turkish researchers found that patients with sleep apnea who were treated with CPAP for three months experienced fewer problems with erectile dysfunction than patients in a control group. This small study showed that treating sleep disorders could have positive effects on sexual performance.
