A laughter therapist's aim is to help you laugh more easily. Therapy is available in group or individual sessions - these start with a warm-up followed by a range of activities designed to get you giggling. Laughter doesn't come easily to everyone, but luckily the body can't actually distinguish between real and fake laughter. So faking it has the same beneficial effect.

As the name suggests, its laughing in order to get a particular result, usually to make us feel better in some way. For starters, it relieves pain, reduces blood pressure and decreases stress.
In 1964, Norman Cousins documented the power of laughter in healing. After being diagnosed with a painful chronic condition, and unhappy with the treatment, he began his own treatment, reading and watching anything that made him laugh. It worked, and he regained his health.
