60 seconds of humming
..' Humming for 60 seconds is a simple, effective tool to promote healing by stimulating the vagus nerve, shifting the body from a "fight-or-flight" state to a "rest-and-digest" state. The vibrations increase nitric oxide, improve breathing, reduce stress, and can lower blood pressure '..

I understand why they use the fake AI's and it is to get people to watch. Irrepsective if the info is valid or not, yet this info is valid. Years ago I got interested in vagus nerve after this opera singing woman, was reported to others { doctors? } that with some of songs she was having an orgasim on stage with peaks of some notes.
I have begun to try practice this humming to help with my anxiety/stress. Ive already found myself sighing more often, in early morning or at night if a awaken and cant get back to sleep. thinking seemingly negative thoughts about my life.
I think the sighing is an automatic response to my stress/anxiety, and tho it is also like a humming, I think there are differrent kinds of humming as well as frequency etc.
