Benefits of Laughter Yoga
The concept of Laughter Yoga is based on a scientific fact that the body cannot differentiate between fake and real laughter. One gets the same physiological and psychological benefits.
Clinical research conducted at Bangalore, India and in the United States has proved that Laughter lowers the level of stress hormones (epinephrine, cortisol, etc) in the blood.

Laughter Yoga helps to change your mood within minutes by releasing certain chemicals from your brain cells called endorphins. You will remain cheerful and in a good mood throughout the day and will laugh more than you normally do.
Laughter Yoga is like an aerobic exercise (cardio workout) which brings more oxygen to the body and brain thereby making one feel more energetic and relaxed.
