It is estimated that 30-50% of adults are predominant mouth breathers! This is despite mounting evidence that nose breathing is much more beneficial to your health. In fact, nose breathing increases oxygen levels in your blood and aids sleep, reduces snoring and improves alertness during the day. Studies demonstrate that nasal blockage increases the chances of asthma, allergies, and sleep apnea. Nasal obstruction can be due to many factors including a deviated nasal septum, enlarged lower turbinates, nasal valve collapse and sinusitis. The correct diagnosis should lead to effective treatment and more open, clear nasal passages that promote healthful living.
