Laughter yoga, it's the best medicine

Laughter yoga is a form of exercise that blends bold belly laughs and noisy "meditation" with rhythmic clapping, waddling around like a penguin or taking part in a conga line, and deep, yogic breathing.

Laughter yoga is a unique exercise that combines laughter with yogic breathing. When we laugh we exhale, and we automatically take a deep inhale afterwards, which is where the yogic breathing comes in.

Other benefits of a good giggle are, that it boosts the immune system, reduces stress, boosts endorphin levels, improves mental clarity and gives a great aerobic workout.

Ten minutes of sustained laughter will give you the equivalent workout of half an hour on a stationary bicycle. Afterwards people lay on the floor to "meditate" amid a cacophony of laughter.
