This practice involves inhaling for 10 seconds while raising the arms to the side of the body up overhead, opened to about a 60° angle. The hands are formed into soft fists with the thumbs pointing toward one another. The breath is held for approximately 40 seconds. exhale slowly for 10 seconds, allowing the arms to come back down to the lap.
This one minute long breath gives us a chance to reset many internal systems. I repeat it twice. It is especially good for warding off repeated headaches.
