Taking short walks outside and actively looking up can shift physiology from a sympathetic to a more parasympathetic state.

“i'm going to take a walk you know i'm going to actively look up you know and acknowledge that my visual system is continuous my with my central nervous system so as i'm myopically focusing in on something say a screen in front of me or a wall in front of me that cues me up to go more into that executive function kind of like get up and atom type place in a little bit more like sympathetic type place as i take in the whole room or take in you know the panorama taking the horizon it sends the cue into my physiology it's like okay obviously paul's not under attack right now or he wouldn't be taking in the whole panorama”
