A 2023 pilot study published in Cureus measured stress using heart rate variability across four activities. Humming, exercise, emotional stress, and sleep. Humming had the lowest stress index of all four. Lower than sleep. The reason it works is the vibration. When you hum, your vocal cords create vibrations that stimulate both branches of your vagus nerve. That activates your parasympathetic nervous system which lowers your heart rate, lowers your blood pressure, reduces cortisol, and releases acetylcholine. Which is basically the chemical that tells your body the threat is over. Humming also increases nitric oxide production which is good for your blood vessels. Source: Trivedi et al.
