Laughter is like a contagious disease, more contagious compared to the different diseases that brings threat to our health. The difference is laughter is way too good. It has good effects to our body like boosting our immune system, increases our energy level and shields us from stress. The kind of medicine that is free and natural.

British study states that opiate-like chemicals are being released from the brain while having a good laugh. These chemicals are useful in dealing with pain. According to biologist, Richard Dunbar from the University of Oxford, those endorphins that are being released are the major reasons for laughter. Endorphins are known to have pain relieving components, similar to morphine.

Dunbar and his colleagues conducted 2 sets of tests. A group watching clips from humorous shows like Mr Bean and Friends, and another group watching a comedy show at Edinburgh Fringe festival. By this way Dunbar observed the tolerance of the participants to pain. The pain has been triggered by a frozen wine cooler sleeve subjected on their arm or a cuff from a blood pressure apparatus was pumped continuously until threshold was reached.

Among all the participants, those who we're at the comedy show who watched for 15 minutes had an increase in pain tolerance by around 10 %. Researchers are claiming that physical exhaustion stimulates abdominal muscles to produce endorphins which are a natural response and a pain control mechanism.

Studies we're conducted before that laughter is also good for the heart, wherein it helps in blood circulation. Laughter also helps in burning calories and fats and it also helps in making the facial muscles supple.

There are a lot of ways to have good health. Doing it naturally, just like having a good chuckle with friends and relatives, is much better to do than going on the artificial side.
