In this episode of Religion Today, host Martin Tanner describes the groundbreaking psychological research of Columbia Professor Allen Bergin, which has been replicated, and shows religious people are happier and healthier than the general population.  Specifically, religiously active people have lower rates of depression, anxiety, suicide, substance abuse, Obsessive-compulsive disorder, Bipolar disorder, PTSD, and eating disorders, than the general population.  And, religious people with these problems are more likely to improve.
