Sleep apnea is a common condition with potentially deadly complications with no treatment. Obstructive sleep apnea is the most prevalent form. It is caused by an obstruction in the upper airway that is created by the soft tissues in the back of the mouth or tongue collapsing. This can result in frequent breathing disruptions while sleeping. Anyone can be at risk of sleep apnea, but there are factors that can contribute to its development, like obesity. Researchers have found that exercise can help improve sleep quality and lessen breathing disruptions.
