Important Note: Your nose is designed to help you breathe safely, efficiently, and properly. Nasal hairs filter out dust, allergens, and pollen. Your nose warms and moisturizes the air you breathe in. This brings the air you inhale to body temperature, making it easier for your lungs to use. Your nose releases nitric oxide, a vasodilator, which means it helps to widen blood vessels. This can help improve oxygen circulation in your body. Inhale during the relaxation part of exercising and exhale during the strenuous part. This helps relax the muscles and allows you to do more reps.
