Religiosity, Well-Being and 'Slowing Down' Ageing Damage: A Literature Review.

Telomere length (TL) represents an important marker of cellular aging. Its shortening affects human health and longevity by inducing senescence, apoptosis, and oncogenesis. Advanced ageing and negative behavioral and lifestyle factors decrease TL. The relationship between positive psycho-social factors and longer telomeres has given rise to a growing number of research efforts. Among these, religiosity poses a particular interest since it is associated with a wide range of favorable health outcomes. In this direction, recent literature reports, suggest a positive link between religiosity and TL. Underlying mechanisms for this association are not yet clarified. In this review, we would like to summarize the current knowledge on the link between religiosity and TL. Taking this opportunity, we recall findings from a cohort study in rural Crete, Greece that adds evidence on the discussion of potential psycho-social mediators which some may prevent shortening of TL.
