There are a number of reasons why breathing through your nose is better than through the mouth. You can take deeper breaths; this improves the oxygen flow to the body. It improves pH levels and a feeling of calmness and helps with athletic performance. Unfortunately, about half of all children regularly breathe through their mouths and this could be harming their health. There are several areas where your child’s health may be affected by breathing through the mouth. Facial developmental issues are a concern, as they can create crowded and crooked teeth. Mouth breathing can also affect facial development. There can be issues with frequent infections, like tonsillitis and ear infections. Mouth breathing can contribute to low energy levels and may cause obstructive sleep apnea. The earlier this is caught in a child, the easier it can be corrected. Oral care that focuses on the position of the tongue and mouth breathing can offer many benefits today and in the future.
