The Butterfly Hug method was developed by Lucina Artigas during her work with the survivors of Hurricane Pauline in Acapulco, Mexico, 1997. Since then, it has been actively used as an anxiety reduction and stabilization technique.
Cross your arms over your chest, so that the tip of the middle finger from each hand is placed below the collarbone. Hand and fingers should be as vertical as possible, so that the fingers point towards the neck and not towards the arms.
You can start with your eyes closed or slightly open. Then tap your hands alternately like the flapping wings of a butterfly.
Aim to breathe slowly and deeply (abdominal breathing) while you observe what is going on through your mind and body such as thoughts, images, sounds, smells, feelings without changing, pushing your thoughts away or judging.
Imagine you are observing it pass slowly like a cloud.
