mouth breathing

Mouth breathing or having constantly open lips is a cause and/or signal of tongue thrust and low tongue rest posture. Long-term mouth breathing compromises the natural process of breathing which relies on the nasal airway to cleanse and purify the air for the pulmonary system making people more prone to asthma, allergies, and even ear tube problems.  Studies also indicate higher risk factors for airway problems at night, decreased concentration, ADHD diagnosis, and poor craniofacial development.
