Sleep apnea is a potentially serious sleep disorder in which breathing repeatedly stops and starts.
If you snore loudly and feel tired even after a full night's sleep, you might have sleep apnea.
A breathing device, such as a continuous positive airway pressure (CPAP) machine, is the most common treatment for sleep apnea.
A CPAP machine provides constant air pressure throughout your upper airways to keep them open and help you breathe while you sleep.
