Lesson Overview

13.3 – Nasal vs. Mouth Breathing Performance Effects: Breathing through the nose filters, warms, and humidifies the air you inhale, supporting stronger lung and heart function. Nasal breathing encourages slower, more controlled breaths that improve oxygen use and protect against dry mouth or throat irritation. Mouth breathing may feel easier during intense exercise, but relying on it too soon can reduce endurance and increase stress. Training yourself to breathe through your nose during lighter activity builds a strong foundation for better performance later. As you improve, nasal breathing becomes easier even at higher intensity. Understanding when to use each breathing method helps you stay efficient and comfortable. This awareness supports healthier lungs, better posture, and improved athletic outcomes.
