What is sleep apnea?

Sleep apnea is a severe medical condition due to narrowing of the airways, especially during sleep. There are many causes for sleep apnea, including being overweight, having a thick neck, or a genetically narrow throat. Though sleep apnea can affect anyone, including children, your risk is increased if you are male, and older. If you are a smoker or use alcohol or sedatives, you also have an increased risk.
