Help Prevent Exercise-induced Asthma with Nose-only BreathingUpdated 25 days ago

Many studies, such as this one, that compare nasal to oral breathing deduce that, during exercise, oral breathing tends to be favorable because not enough air can be inhaled through the nose. Even for those of us with physiologically “perfect” noses, nasal breathing during exercise (especially without a nasal dilator) has to be practiced in order to see physical benefit. For athletes that do adapt to nasal breathing, case studies show that both oxygen absorption and time to exhaustion is greater than athletes who rely on oral breathing during exertion. Nasal breathing has also been shown to help prevent exercise-induced asthma by reducing post-exercise bronchoconstrictive response.
