Researchers from Vanderbilt University in the US found that adults between the age group of 40 to 65 years who attend church or other houses of worship reduce their risk for mortality by 55 per cent.
"Our findings support the overall hypothesis that increased religiosity - as determined by attendance at worship services - is associated with less stress and enhanced longevity," said Marino Bruce, research associate professor at Vanderbilt University.
"We have found that being in a place where you can flex those spiritual muscles is actually beneficial for your health," Bruce said.
Allostatic load is a physiological measurement of factors including cardiovascular (blood pressure, cholesterol-high density lipoprotein ration), nutritional/inflammatory (albumin) and metabolic (waist-hip ratio, glycated hemoglobin) measures.

The higher the allostatic load, the more stressed an individual was interpreted as being.
Researchers found that non-worshippers had significantly higher overall allostatic load scores and higher prevalence of high-risk values for three of the 10 markers of allostatic load than did church-goers and other worshippers.
"We found that they go to church for factors beyond social support. That is where we begin to think about this idea of compassionate thinking, that we are trying to improve the lives of others as well as being connected to a body larger than ourselves," Bruce said.
The study was published in the journal PLOS ONE.
