Breathing through your nose filters air, changes the air temperature, moisturises the air and produces nitric oxide which allows better uptake of oxygen into the body. Nose and diaphragm breathing is how we should breath and so many people miss this simple thing every day. By pulling and blowing air through your nostrils you are restricting the flow which means longer and slower breaths are easier to do. Long and slow breaths are linked to rest and digest nervous systems which is calming and healing. Short and shallow mouth breaths are linked with fight and flight, stressful nervous system which isn’t good on a daily basis! Constant mouth breathing is BAD!! In children, mouth breathing all the time can cause crooked teeth, facial deformities, or poor growth. In adults, chronic mouth breathing can cause bad breath and gum disease. It can also worsen symptoms of other illnesses. On the contrary, mouth breathing stimulates the fight and flight branch of our nervous system and, over time, can even change your facial structure, especially if adopted from a young age. Breathing through you nose with your mouth closed and tongue up on the roof of your mouth can change all of this!
