Share a hearty laugh with friends can help you with pain, thanks to chemicals, similar to opiates, invading the brain when we laugh, according to a British study published in the journal Proceedings of the Royal Society B, the Academy of Sciences Great Britain.
Scientists did laboratory experiments in which volunteers watched, sometimes comedy clips from the series “Mr. Bean “or” Friends “, now the stretches of non-comedy shows, such as a round of golf or programs on wildlife, while its resistance to pain was monitored.
In another test, performed at the Festival ‘Fringe’ Edinburgh – Annual event featuring comedy shows, dance, theater and music – volunteers watched either a comedy number of ‘stand-up’, now a theatrical drama. In laboratory conditions, the pain was caused by ice in contact with the arm of volunteers and a pressure gauge that pressed his fist to the limit of what is bearable.
The Festival ‘Fringe’, was asked to volunteers who incline against a wall with your legs at right angles, as if they were sitting in a straight-backed chair, before and immediately after the show to see if laughter had helped reducing pain.
According to the study, only 15 minutes of laughter increased the level of pain tolerance by about 10%.
In laboratory experiments, the non-humorous programming not shown to have any effect of relieving pain, or seeing a dramatic piece at the Festival ‘Fringe’.
The study showed, however, two important distinctions.
The only laughter that worked was that relaxed, not stressed, which makes them tighten eyes, unlike the nervous laughter or polished.
This type of laughter is much more likely to happen when you are in the company of others than alone.
“Using microphones, we were able to record each of the participants and found that in a comedy show they laughed for about a third of the time and his pain tolerance increased as a result,” he added.
This protection derived apparently from endorphins, a complex chemical that helps transmit messages between neurons but also attenuates the signs of physical pain and psychological stress.
Endorphins are a famous product of physical exercise. They help to generate well-being that follows the practice of activities such as running, swimming, rowing, yoga, etc.
In the case of laughter, scientists believe that the release of the substance occurs due to repeated and involuntary muscular effort that is when the expiration is not followed by the taking of breath. Venting let us exhausted and therefore leads to the release of endorphins.
