There are activities and even colored lenses that can activate either system.

Syntonics is a form of this some eye doctors use to help correct alignment issues. That tapping of the shoulders we saw Prince Harry do is another. The Vagus nerve is part of what you want to stimulate for the parasympathic nervous system activation, in my understanding.
