As humans, we were not designed to breathe through our mouths. Except in “emergency” situations in which we are not able to get enough oxygen through our nose, like having a cold or certain aerobic exercise situations.

As a general rule, the mouth is for eating and talking, and the nose is for breathing.

Mouth breathing is one of the most common and unhealthy habits that a person can develop. Why is it such a problem?

• You are taking in less oxygen. Does not allow as much oxygen to be taken up in the lungs, often up to 20% less!
• Shallow or thoracic breathing. Ideally we breathe deeply and with our diaphragm. Mouth breathing does not allow for deep, quality breaths. This results in a constant state of “fight or flight” (your body thinks you are running from a prehistoric creature ALL THE TIME!)
• Your body does not produce nitric oxide at appropriate levels. Nitric oxide is produced by the sinuses and has a few importance functions. It kills many harmful bacteria and viruses before making it to the lungs. This improves your immune system, improves oxygen uptake in the lungs, and assists in dilating the blood vessels (which manages blood pressure).
• Changes the position of your tongue at rest. This can effect craniofacial development (the way you look), cause tooth crowding, and develop improper swallowing patterns.
• Can lead to increased tooth decay (cavities) and gum disease. Breathing through the mouth dries out the oral cavity and tissues, resulting in an environment more suitable for bacteria to thrive.

Establishing nasal breathing is one of the 4 main goals of Myofunctional Therapy. By retraining poor breathing habits and establishing predominant nasal breathing, you will be on your way to a much healthier and happier body and mind!
