Sport and stuffy nose.
Well-oxygenated muscles hurt less.
Nasal breathing encourages the production of nitric oxide, a gas that promotes the binding of oxygen to red blood cells. This supply of oxygen slows down lactic acid buildup and reduces muscle soreness during exercise.
During sustained exertion, RespiFacile® also reduces the work of breathing, or the amount of energy needed by the respiratory muscles to alternate inspiration and expiration.
