Religion and health

There is considerable literature on the relationship between religion and health. More than 3000 empirical studies have examined relationships between religion and health, including more than 1200 in the 20th century, and more than 2000 additional studies between 2000 and 2009.

Psychologists consider that religion may benefit both physical and mental health in various ways, including encouraging healthy lifestyles, providing social support networks and encouraging an optimistic outlook on life; prayer and meditation may also benefit physiological functioning. Nevertheless, religion is not a unique source of health and well-being, and there are benefits to nonreligiosity as well. Haber, Jacob and Spangler have considered how different dimensions of religiosity may relate to health benefits in different ways.
