This is a Qigong exercise from Dr. Libby. she says these calming exercises get us out of the flight or fight mode and into the green zone which is the rest and digest mode of the nervous system.
With all the stress in today's world, these are great movements to calm you down and help you deal with your anxious feelings.
I have written a book on how to manage stress and anxiety in the 20th Century and how Tai Chi can help. I include some simple Tai Chi basic movements that you can practice anywhere when you need to calm your nervous system.
