Bryan Johnson uses a Parasym device that stimulates the vagus nerve to shift your nervous system toward relaxation. High heart rate variability means you're in chill mode; low HRV means stress. He does 30 minutes of mild electrical stimulation each morning and evening, feeling a light tingling sensation.
I'll start with some HRV therapy. Heart rate variability. Hrv. It is a representation of your nervous system. And so when you're stressed out and you're in fight or flight mode, you're in a heightened state of stress. And when you're chilled out and relaxed, you're trying to get your body to be in a more relaxed state. We've tried a lot of devices over the years, probably 15 or so. This one is from Parasym, and it attaches right here to this part of the earth. I've been doing 30 minutes in the morning and 30 minutes in the evening. This device is immediately emitting electrical current. And so we have a vagus nerve that is through the side of our head in the air is a connection point, then down through our gust. It's an entry point for a lot of things. People use the vagus nerve for all kinds of treatments of disorders. And so by putting this thing here, it just electrically stimulates so I can feel a really light source of electricity.
