This is part one ofa two-part partial literature review on the impact of mouth breathing. Mouth breathing is defined as breathing through the mouth instead of the nose. In this review, we will shed some light on the causes, symptoms, and diseases correlated with mouth breathing. The second article, defined as part-two, will introduce forms of therapy to encourage nasal breathing, one of which will focus on the Butevko® breathing method.
