It took me far too long to realize that something as basic as the way you breathe can radically impact your health, performance, and even how your face develops.

For most of my life, I thought breathing was… just breathing. Automatic. Not worth questioning. But there’s a world of difference between mouth breathing and nose breathing. And once you understand that difference, you’ll never look at it the same again.

Mouth breathing is tied to disease, poor sleep, stress, and low endurance. Nose breathing, on the other hand, is how your body is designed to function—filtering air, producing nitric oxide, balancing your nervous system, and improving oxygen efficiency.

Small shifts in your breathing habits can compound into massive improvements in health and longevity. That’s what this issue is about.
