laughter improves people's emotional and well-being.   kavita khajuria is a psychiatrist and he has defined laughter as " physical expression of humour and joy that has numorous protective qualities." when you feel under stress or sad because you have argued with a person you love, you need to laugh to feel strong enough to face the problems.
