Ommmm…..
Studies have revealed that humming significantly increases nitric oxide production by the brain with some studies showing an incredible 1400% increase in just 10 seconds.
Nitric oxide is a gas that acts as a crucial chemical messenger in the body, primarily by relaxing blood vessels to improve blood flow and blood pressure. This gas is produced in the brain, where it is synthesized by different cell types, including neurons, glial cells, and endothelial cells lining blood vessels.
Humming increases nitric oxide production by using oscillating airflow to improve gas exchange between the paranasal sinuses, which produce nitric oxide, and the nasal cavity.
Increased nitric oxide production is excellent for your health as it relaxes and widens blood vessels, which improves blood flow, lowers blood pressure and delivers more oxygen and nutrients to muscles and organs. This leads to benefits like improved cardiovascular health, better exercise performance and recovery, enhanced brain function and a stronger immune response.
NOTE: In my fact checking this, the AI Overview on google said “this claim is an exaggeration, nitric oxide production is increased by 15 fold not 1400%”… 15 fold is 1400% so just shows you can’t always trust AI…
