Vagus is Latin for wandering. It wanders from your brainstem, past your heart and lungs, all the way to your gut.
About 80% of its fibres carry messages up, from your body to your brain. Your gut reports in all day.
Your heart's own pacemaker runs at around 100 beats a minute. The vagus nerve's steady brake holds it nearer 60 to 80 at rest.
It runs the muscles of your throat and voice box. That's why humming and singing turn up on every vagus-nerve list.
Your gut decides what you eat. What you wear. Whether you go out at all.
I know, because mine fell apart too. I tried everything, and still suffered.

In for four as the dots travel down. Out for eight as the ring glows. The long breath out is the half your body reads as safe.
That was the in-the-moment half. Vagus One is the everyday half: what the nerve runs on.
Sit down for this, and stop if you feel light-headed.
Vagus nerve support, redefined. Calm, built from the nervous system up.
