Ten percent of adults worldwide are believed to have obstructive sleep apnea, and men are twice as likely to develop it.
During sleep apnea, your brain senses a lack of oxygen and wakes you up just long enough for you to take a breath, and you then fall back asleep. This cycle repeats throughout the night and causes poor, disruptive sleep.
Interrupted and poor-quality sleep can lead to daytime sleepiness and fatigue, impaired attention and memory, headaches, depression and sexual dysfunction. Daytime sleepiness leads to a higher risk of motor vehicle accidents in people with obstructive sleep apnea. Obstructive sleep apnea is also associated with an increased risk of developing insulin resistance, which is an inability to regulate blood sugar levels effectively. It also can contribute to high blood pressure, heart disease and stroke.
