Why is Mouth Breathing So Important?

By breathing through the nose we solve the above problems, but most importantly we dramatically increase the body’s oxygenation. This happens because of the production of Nitric Oxide in the nasal passages that we inhale through the nose with each breath. This all important NO, aside from being a potent vasodilator that opens the arteries and veins, greatly improves the lungs’ capacity to utilize the oxygen in the air we breathe. Oxygen is the body’s most important nutrient, and this is why people with a wonderful diet of nutrient-dense vegetables might still find themselves with health problems—they’re failing to adequately obtain the nutrition of air!
