What is sleep apnea?

ANSWER

Sleep apnea is when your upper airway is blocked, interrupting regular breathing for short periods of time -- which then wakes you up. It can cause severe daytime sleepiness. If it's not treated, severe sleep apnea may be linked to high blood pressure, stroke, and heart attack.
