There is now extensive research suggesting that religious people are happier and less stressed.[1][2]
Surveys by Gallup, the National Opinion Research Centre and the Pew Organization conclude that spiritually committed people are twice as likely to report being "very happy" than the least religiously committed people.[3]
An analysis of over 200 social studies contends that "high religiousness predicts a rather lower risk of depression and drug abuse and fewer suicide attempts, and more reports of satisfaction with life and a sense of well-being"[4] and a review of 498 studies published in peer-reviewed journals concluded that a large majority of them showed a positive correlation between religious commitment and higher levels of perceived well-being and self-esteem, and lower levels of hypertension, depression and clinical delinquency.[5][6]
Studies by Keith Ward show that overall religion is a positive contributor to mental health[7] and a meta-analysis of 34 recent studies published between 1990 and 2001 also found that religiosity has a salutary relationship with psychological adjustment, being related to less psychological distress, more life satisfaction, and better self-actualization.[8]
Finally, a recent systematic review of 850 research papers on the topic concluded that "the majority of well-conducted studies found that higher levels of religious involvement are positively associated with indicators of psychological well-being (life satisfaction, happiness, positive affect, and higher morale) and with less depression, suicidal thoughts and behavior, drug/alcohol use/abuse."
