Hum songs through the nose to increase the release of nitric oxide and improve your breathing.
Nitric oxide is a powerhouse molecule that widens capillaries, increases oxygenation, and relaxes the smooth muscles. Humming is the most effective, and simple, method for increasing this essential gas. In fact, humming through the nose increases the release of nitric oxide in the nasal passages 15-fold. This breathing technique will improve your health and your enjoyment of life!
Breathe normally through the nose and hum any song or sound of your choosing.
Practice for at least five minutes a day, more if possible.
It may sound ridiculous, feel ridiculous, and annoy those nearby, but the effects can be potent.
