"In people with blood pressure, heart disease and diabetes, we have noticed a 50 percent improvement in their health due to laughter exercises. I am not saying it completely cures diseases, but there is reduction in medication," he explained.
Kataria said there are around 10,000 laughter clubs in India and the demand is increasing in other parts of the world too.
"They are present in around 72 countries like Japan, Germany and US," he said.
Chandhok said that yoga or meditation or laughter sessions are important for a healthy life, but medical treatment is equally vital.
"Treatment is essential. Complete it and then continue with these healthy activities," he said.
So, step out and have a hearty laugh.....ha, ha, ha, ha!
