Typically, people breathe through their nose when they sleep. If you snore, it means you’re breathing through your mouth. It not only can affect your sleep, but it can cause partners to sleep in separate rooms. Recent evidence suggest snoring may cause thickening of the carotid arteries over time and potentially increase the risk of stroke. Snoring may be a sign of obstructive sleep apnea. Lifestyle changes, such as losing weight, avoiding alcohol close to bedtime or sleeping on your side, can help stop storing. If these changes do not help, your doctor can help identify if you have obstructive sleep apnea.
