Pain reduction
Giving seems to lessen our pain. A recent study found that people who said they would donate money to help orphans were less sensitive to an electric shock than those who declined to give. In addition, the more helpful people thought their donation would be, the less pain they felt.
How could this happen? The study found that regions of the brain that react to painful stimulation appear to be instantly deactivated by the experience of giving.
Happiness
In the UK, researchers found that being kind could boost happiness in as little as three days. The study assigned people to three groups: the first group had to do an act of kindness each day; the second group tried a new activity; and the third group did nothing. The groups who were kind and did novel things saw a significant boost in happiness.
