muscles used in laughter

Laughter can sometimes be seen as a medicine, with no price or prescription needed! Not only does laughing decress blood pressure, strengthen the immune system and improve breathing but it also reduces pain and releases stress. When we laugh fifteen of our facial muscles contract and we start to breathe irregularly, often sruggling for air and in some people, their tear ducts become activated.

Many factors of a person determine what they do and dont find funny, the three most common are Age, Level of Intelligence and maturity. However psychologists have come to the conclusion that we dont always laugh because we find something funny or humerous. We also laugh when we feel nervous, happy, tense or excited and it is known that the sound of someone laughing makes people laugh, this is why it is common for the speaker to laugh as then the listener will laugh and the speaker will feel comfortable that they have got the response they had hoped for.
