Experiments show that acting for others relieves physical pain
Some people may have wondered about what they do for kindness or volunteering. Although kindness that does not seek reward sometimes seems to create a loss for the person himself, new research shows in multiple experiments that “ action for others '' alleviates the physical pain of the person who acted it was done.

A study published in 2019 showed that the act of "hoping for the happiness of others" reduced anxiety, increased empathy, and made people feel more connected. In this way, the kind feelings about othersDopamineAndOxytocinEncouraging the secretion of such neurotransmitters has been recognized so far. Peking University Psychology and Cognitive Science researchers take steps from here to act for othersAltruistic behaviorInvestigated whether it alleviated the person's physical pain.
To test this hypothesis, researchers performed four experiments on 287 subjects using various scenarios.
One experiment showed that those who donated blood after the quake experienced less pain when donating blood with a thicker needle than those who donated blood as a habit. In another experiment, subjects voluntarily revised the handbook for children and migrant workers, and those who volunteered suffered pain when exposed to the cold outside air compared to those who did not. It was hard to feel.
Furthermore, when cancer patients with chronic pain were collected and asked to clean the treatment center “ for themselves '' or “ for others, '' those who cleaned for others had a lower level of damage. Yes. At this time, researchers said that those who cleaned for themselves had 62% less pain relief than those who did for others.
The most notable effect was the experiment of "donating to help orphans." In this experiment, people who chose to "donate" were asked, "How much do you think this donation would help?", And then an MRI scan of the brain with an electric shock to the arm.
Then, the brain of the person who made the donation was less responsive to electrical stimulation than the person who did not. Also, at this time, the more he believed that his altruistic behavior helped others, the less his brain responded to pain.
"For centuries, scientists have been thinking about the question: why humans help others until they suffer losses, and what does this mean for actors?" Those who have performed passive behavior, directly or indirectly, have shown that they will make up for future losses, and our research has shown that altruistic behavior has In such a deep situation, it shows how it affects the senses of the actors, "said the researcher in a dissertation.
