Vagus Nerve Stimulation for a Big HRV Boost

The Bizarre Biohack That Made Me Calmer and Improved My HRV

For the last 30+ days I’ve been zapping my left ear with electricity. Did it hurt? Sometimes.

Was it worth it?

Totally!

I’m a big fan of biohacking and Bryan Johnson is one of the best known people in the industry. While I don’t agree with some of his practices (and the cult-like approach), I do appreciate him doing so much testing on himself.

Especially since some of his tests backfire (like the infamous rapamycin one).

In his Netflix documentary, one device in particular caught my attention. It was a small neuromodulator that you attach to the tragus of your left ear. (It’s that little part that sticks out on the opposite side of the earlobe.)

By pulsing into that point with low-current electricity, it stimulates your vagus nerve.

What is the vagus nerve?
