Airway Size Matters

A healthy airway can have a profoundly positive impact on athletic performance. It is no accident that many of the world’s top athletes have robust, Chad-like faces.

It’s pretty simple, really. If you have a bigger airway, your body can fuel more metabolism, and therefore produce more energy.

This is especially important during max-exertion activities like sprinting and fighting.

Your ability to sprint is directly related to your ability to take in big gulps of air in a short period of time. Obviously, the bigger your jaws, the easier it is to do this, and the more intensely you can exert.

Mouth breathing has its own dire consequences for athletic performance as we will see below.

Nasal Breathing Brings Bliss

Large jaws allow an athlete to draw sufficient air through the nose while simultaneously resting the tongue up and forward out of the throat and onto the roof of the mouth.

What results is habitual nasal breathing, even during strenuous exercise.

Nasal breathing during exercise is a game changer. In general, it makes athletics more euphoric and less laborious, and therefore more sustainable.

We are more likely to do things that make us feel bliss rather than pain.
