Do Good - Feel Good!

We've long been taught that helping others helps ourselves. Now science has shown that altruistic behaviors -- defined as putting the well-being of others before our own without expecting anything in return -- actually do improve our health.

A new study may have found one reason why: regions of the brain that react to painful stimulation appear to be instantly deactivated by the experience of giving.

One found that those who volunteered to give blood after an earthquake experienced less pain than those who did a routine test, despite the use of a larger needle. A second discovered people who freely gave their time to revise a handbook for the children of migrant workers experienced less pain when exposed to cold temperatures than people who did not volunteer.

In another study, the researchers recruited cancer patients living with chronic pain and asked them to cook and clean for themselves or for the benefit of others at their treatment center. When they were helping others, their pain levels dropped. When they did the work for their own personal benefit, the pain-relieving effect was reduced by over 62%.

In the most telling study, researchers asked participants to consider donating money to help orphans; if they chose to do so they were asked to rate how helpful they believed their donation would be. The brains of those participants were then scanned via MRI while they received a nasty electric shock to their hands.

Results showed the pain-control centers in the brains of those who donated reacted less to the painful sensation than those who did not give money. Not only that, but the more people believed their altruistic actions were helpful, the less their brain responded to the pain.

In addition, the authors found it was the meaning people gave to their good deeds that predicted how much pain the brain would perceive. While more research is needed, the authors believe that medicine should consider using altruism to "supplement current behavioral therapies to treat pain." Prior research also found the act of giving stimulated the reward centers of the brain, producing a sort of "helper's high." A reduced sense of pain combined with feel-good chemicals -- it seems our brains reward us for helping others even when we're not expecting anything in return. Sounds like a great reason to put volunteering and other giving behaviors on your to-do list in this new year to improve your health and others'.
