Nitric oxide plays a major role in relaxing blood vessels to help control blood pressure and circulation. Beyond diet and supplements, there’s a surprisingly simple way to increase nitric oxide — and it has to do with how you breathe.
The Power of Humming
Researchers found that humming — which requires breathing in and out through your nose — increased nitric oxide 15-fold in the nasal mucosa.
Why This Works
It turns out the lining of the nasal mucosa is full of an enzyme called nitric oxide synthase, which is activated by airflow. When you breathe in and out through your nose, you naturally increase nitric oxide production. This, in turn, helps open blood vessels, lower blood pressure, and improve circulation to the brain.
It’s a simple, free practice — a few minutes of nasal breathing or humming could offer real circulatory benefits alongside diet and supplements.
