1 . The joy of giving is real, according to a study. Research presented in the Journal of the Association for Psychological Science shows that those who give gifts are happier — and happier for longer — than those who receive gifts.

Researchers conducted two studies last year. In one，participants were given $5 every day for five days and were required to spend the money on the same thing each day. Some participants were required to spend the money on themselves, while others were required to give to make a donation to charity. In a second experiment that was done online, participants played 10 rounds of a word puzzle game and each won 5 cents per round, which they could keep or donate.

In both experiments, participants reported their overall happiness. Those who donated their money showed that their happiness declined at a much slower rate than those who kept the money or spent it on themselves.

The researchers note that when people focus on an outcome, they can easily compare outcomes, which may diminish their sensitivity to each experience. When people focus on an action, they may focus less on comparison and instead experience each act of giving as a unique happiness-inducing event. Further analyses ruled out some potential alternative explanations, such as the possibility that participants who gave to others had to think longer and harder about what to give, which could promote higher happiness.

The results are especially interesting because according to one of the researchers, Ed O’Brien of the University of Chicago Booth School of Business, they conflict with past research. “If you want to sustain happiness over time, past research tells us that we need to take a break from what were currently consuming and experience something new. Our research reveals that the kind of thing may matter more than assumed: Repeated giving, even in identical ways to identical other，may continue to feel relatively fresh and relatively pleasurable the more we do it,” O’Brien said.

So for all the holiday gifts you give this season, expect to feel happy and know that feeling is going to stick around for a while.
