Altruism leads to reduction in physical pain: Study

Washington D.C. , Dec 31 : Helping others without expecting any benefits in return might actually be good for our own physical wellbeing.

Acts that involve putting the interests of others before our own, for instance, volunteering, are known to have a positive impact on stress, depression and cognitive impairment. Moreover, it may even lead to an increased lifespan, reports CNN Health.

The benefits of altruism don't just end here, because as revealed by a 2017 study, acts of kindness led to reduced levels of pain in volunteers, who already suffered from chronic pain issues.

New researches on this phenomenon attribute the pain-reducing effect of altruism to its ability to deactivate the regions of the brain that respond to a painful stimulus.

A series of studies published this Monday in the Proceedings of the National Academy of Sciences analyzed the effects of altruism on 287 people under different situations.

The first one revealed that the participants who volunteered to donate blood to earthquake victims had a reduced sensation of pain as against the ones who underwent a routine blood test. In this experiment, the blood donors showed better outcomes in spite of being pricked by a larger needle.

Another study observed the effects of discomfort caused by cold on participants who volunteered to revise handbooks for children of migrant workers. It turned out that the people who volunteered in the selfless act suffered less pain as compared to those who didn't.

The next study asked cancer patients suffering from chronic pain to cook and clean either from themselves or for others. The participants reported a significant reduction in pain when they were working for others. The pain-reducing effects fell by 62% of the participants who only worked for themselves.

The study that put forth the most compelling evidence tested the pain response of participants who were asked to consider donating money for orphans. Electric shocks were administered on the hands of the subjects while they were placed inside an MRI machine.

The pain centres of the volunteers who donated money reacted less intensely as compared to the ones who didn't give any donations. Moreover, the subjects who believed that their contribution would be more helpful towards the cause were less responsive to the painful electric shocks. So, an inverse relation was seen between the perceived usefulness of the altruistic act and the degree of perceived pain.

Previous research has established a link between kindness and the activation of the brain's reward centres. Thus, reduction in pain when combined with a rush of happiness can synergistically improve our health and help us live longer.
