Your nose is built for breathing. It filters, warms, and humidifies the air, and it triggers nitric oxide that opens up your airways and improves oxygen delivery.

Nasal breathing improves CO₂ tolerance and oxygen delivery to tissues, significantly reduces snoring, and shifts you into a calmer, parasympathetic state.
