The usual treatment for sleep apnea is a CPAP mask, which increases air pressure to keep your airway open. But Brazilian researchers found that simple throat exercises may also help treat sleep apnea. People who performed the exercises for half an hour a day reduced the severity of their condition by 39 percent in 3 months. The workout strengthens your upper airway, so it won’t collapse during sleep. If you have moderate sleep apnea, talk to your doctor about trying the exercises.
