Although it sounds harmless, breathing through your mouth causes the body to work overtime. Many of us breathe through our mouths due to nasal congestion, a deviated septum, or small nostrils. No matter the cause, mouth breathing increases the risk for a large list of health conditions, such as heart disease, anxiety, chronic stress, tooth decay, and more. In contrast, nasal breathing helps the body (and brain) operate more efficiently than ever before. The benefits of nose breathing are seemingly endless. Nasal breathing helps to boost our immunity, improve cardiovascular health, enhance sleep quality, prevent snoring, and more. If you aren’t already a nasal breather, these five benefits of nose breathing just might convince you to become one.
