A scientific explanation of why people laugh is like this
Sabrina Stillwald, a part-time lecturer at the California Institute of Technology and the University of Virginia, provides a scientific explanation of why humans laugh.
Why Do We Laugh? Science Has Surprising Answers
In recent research, it has been confirmed by experiments that even mice enjoy `` hide and seek '' and raise ultrasonic laughter, jump and joy, and it has also been found that laughter is not a human rights patent .
On the other hand, it has also been confirmed that “it is not a physical reaction that a baby who cannot understand words and jokes laughs”, suggesting that laughter has more than just a reflection.

An experiment that demonstrates the idea that laughter is not just a reflexive activity is to show a group of children between the ages of two and a half to four years old. During the experiment, the children asked `` when they watched animation alone '' and `` when they watched together with other children '' and asked which one felt more interesting. 'It's so interesting.'
However, when I observed how I actually watched anime, I was laughing 8 times more often than when I was alone with other children. This shows that human laughter has a function as a communication tool.
In an experiment with 966 participants living in 24 regions, the participants were able to “distinguish between friends and non-friends” with only a short laughter. In other words, laughter also has a function as a means of identifying close people.

Regarding the origin of laughter as a communication tool, Stillwald believes that there is a hint in “ social grooming ” between animals. Social animals make haircuts and communicate with each other to make sure they are friends, but the human community is too big to make haircuts for all of them.

Therefore, Mr. Stillwald believes that humans have used “laughter” as a means of clarifying peers and those who are not, at the stage of developing groups and forming organizations.
Laughter also has a health effect . When you laugh and take up a lot of oxygen in your body, endorphins are secreted in your brain, which helps you relax. At the same time, the heart rate, lungs, and muscles are stimulated to stabilize the pulse and blood pressure. In the long term, laughing well has been shown to improve immune function and prevent depression. Because of these benefits, doctors at the major American general hospital Mayo Clinic argue that “laughing is the best medicine”.
Stillwold said, “Laughing has the effect of promoting the most important“ cooperation ”for human survival and promoting health. This is how I spend time for dinner and drinking with friends. It ’s perfect for justification, ”he stressed, and that smiles have a science-backed merit.
