According to Dr Janet Goodrich, a psychology, we often restrict energy flow through our whole body by unconsciously holding our breath when we want to yawn. This ‘impolite’ yawn is, in fact, the most naturally freeing and the fullest kind of breathing possible when we have a spontaneous need for fresh oxygen, stretching of muscles, and a change of pace.

In her book, “Natural Vision Improvement – Improve your eyesight and enjoy life more”, Goodrich listed the following benefits of yawning.

(1) Yawning brings fresh oxygen into our body cells, including those in the eyes and brain.

(2) Yawning contracts and expands muscles from the top of our head to the tips of our toes, including those in the eyes, neck, shoulder and belly.

(3) Yawning is capable of changing our emotional states from negative to positive.

(4) Yawning changes the pH of the blood reducing toxicity levels in our whole body system.

(5) Yawning opens our minds to new experiences and ideas.

(6) Yawning helps to detoxify our liver and to balance the energy in the liver meridian.

(7) Yawning wakes us up in the morning and clams us down for deep restful sleep at night.

(8) Yawning stimulates the production of refreshing tears that bathe our naturally tired eyes and moisten the chronically dry eyes.

(9) Yawning relaxes our solar plexus area and tummy muscles that accompany indigestion.
