Gotta tell you I used the breath work to a great advantage a couple of weeks ago. I had to have emergency oral surgery. I was hooked up to EKG and BP cuff. I was not prepared mentally it emotionally for going under the knife or anesthesia. Everything was elevated. I felt horrible anxiety laying there waiting. Watching my blood pressure at 155/120. (Way higher than normal) and heart rate 101-110. So, all I could do was to breathe. And I brought everything down into the normal zone in less than 10 minutes. Might have taken less time but I was being poked etc. and anxiety disappeared too. Whew!!
