Sleep apnea is a condition that causes a person to stop breathing for short periods while sleeping. Treating this condition requires lifestyle change such as eating healthy, exercising regularly, and avoiding alcohol and smoking.
Doctors often recommend people with sleep apnea to maintain a healthy weight, as obesity can increase the risk of airway obstruction and narrow nasal passages. This relates with exercising regularly because engaging in an active lifestyle helps one achieve an ideal weight. Moreover, exercise, especially yoga improves a person's respiratory strength and oxygen flow. Alcohol and smoking, on the other hand, could cause inflammation and swelling in your airways; hence, it would be best to avoid them.
Apart from these, you may also try changing your sleeping position. Some studies have shown that sleeping on your back can worsen the symptoms. If this case holds true for you, then you may want to try sleeping on your side.
