The 'helper's high' could help you live a longer, healthier life.

It's a classic tale, the story of Ebenezer Scrooge -- the epitome of selfishness, the quintessential mean-spirited, miserly, narcissistic old man. Yet as Scrooge discovers the joy of good deeds, he blooms with the "helper's high" - and his spirit is reborn. And a merrier man had never been seen, as the story goes.

In the last few years, researchers have looked at the so-called helper's high and its effects on the human body. Scientists are searching to understand just how altruism -- the wish to perform good deeds -- affects our health, even our longevity.

Acts of heroism are one form of altruism -- as we saw on 9/11, when firemen rushed into the World Trade Center. Many firemen, chaplains, and citizens joined the rescue and recovery effort, working grueling 12-hour shifts.

In everyday life, countless people choose to give up free time to volunteer -- whether it's serving at soup kitchens, cleaning up litter, taking elderly people to the grocery store, or helping a next-door neighbor.

What prompts a human being to act heroically? What makes us perform good deeds? When we act on behalf of other people, research shows that they feel greater comfort, less stress. But what about the do-gooder's physiology -- how is it affected? Can doing good make us healthier, as a growing number of scientists now believe? Can it even, as studies suggest, help us live longer?

This is the focus of 50 scientific studies funded through The Institute for Research on Unlimited Love, headed by Stephen G. Post, PhD, a professor of bioethics at Case Western Reserve University School of Medicine. It is a comprehensive investigation of altruism, aka benevolence, compassion, generosity, and kindness.
