One study finds believing in a higher power may help fend off anxiety.
The research from the University of Toronto found the brains of religious people reacted differently to anxiety than those of non-believers.
Researchers measured the brain activity of a group of people while they were taking a cognitive test.
Compared to non-believers, the religious group showed less activity in a portion of the brain that fires up when we make a mistake or feel uncertainty.
Those with the strongest belief in god had the smallest reaction to stress.
