Why is it better to inhale through your nose and exhale through your mouth?

Inhaling through the nose allows for better filtration, humidification, and warming of the air before it reaches the lungs, which can enhance respiratory health. The nasal passages also facilitate the production of nitric oxide, which helps improve oxygen uptake. Exhaling through the mouth can help release carbon dioxide more effectively and is often more comfortable during physical exertion or when practicing breathing techniques. This combination promotes optimal oxygen exchange and can enhance overall breathing efficiency.
