Understanding obstructive sleep apnea
What Is Sleep Apnea?Obstructive sleep apnea (OSA) happens when the soft tissues of your throat relax and collapse during sleep, repeatedly blocking your airway — sometimes hundreds of times a night. Each blockage jolts your body out of deep sleep to restart breathing. The result: daytime tiredness, and over time, elevated risk for high blood pressure, heart disease, stroke, and diabetes. Snoring is often the loudest warning sign.
