This Thanksgiving, take time to be grateful. It's not just a nice holiday tradition. It can actually improve your health.
Researchers at the University of California, Davis analyzed the effects of gratitude in a series of studies. In the first, participants were asked to keep a weekly journal and write about five events from the previous week. They were randomly assigned to one of three groups. One group wrote about things they were grateful for. Another group wrote about hassles they experienced. The last group wasn't given any direction on choosing positive or negative events.
