[ Is the lack of religion bad for your health? In a large survey of over 600,000 people Frank Newport and colleagues showed that the very religious not only report higher levels of overall wellbeing they are also more likely to have healthy eating and exercise habits. ]
I agree with this although it depends on the religion. Members of Christian denominations has this kind of effect on them. Maybe because they have a peace of mind that whatever happened, their God will save them in the end long as they trust and fear Him.
