But what if changing the way you breathe could potentially help protect you from the very thing that threatens your ability to breathe? That’s one theory some experts are suggesting. It has to do with the simple physiology of the nose, and the chemical compound nitric oxide (NO).

The mucus and cilia inside are designed to block these outside invaders from going farther down the respiratory tract and making you sick. And NO, which is what the sinuses release when you breathe through your nose, is a vasodilator, meaning it relaxes the blood vessels and lowers blood pressure.
