Whatever it is that you’re fretting about, here's a bit of good news: Worrying can be beneficial, under certain circumstances.
Dr. Kate Sweeney, an associate professor of psychology at the University of California, Riverside, and co-author of new research on the upside of worrying, says it serves a few useful functions.
“The most important function that worry serves is that it acts as a motivator,” Sweeney says. “It essentially tells us there is something we should be doing. And it gives us the motivation to do it.”
