Laughter yoga is typically performed in groups. Yogis may begin with gentle stretching warm up exercises, and perhaps clapping or chanting. They may make eye contact and communicate with each other to reduce inhibitions, then, breathing exercises are often used to prepare the respiratory system for laughing before the laughter exercises are performed. These may include visualization techniques or acting. Often, voluntary laughter leads to natural or contagious laughter. It is said that 20 minutes of laughter is enough to feel the full benefits of the practice.
Laughter yoga is said to be good for anyone who wants to bring more joy, playfulness and sociability into their life. It is also claimed to help the body and mind feel more energized and healthy. Some studies suggest that laughter lowers stress hormone levels and may improve tolerance of pain. Yogis may leave their session feeling uplifted and peaceful.
