Describe the link between stress and premature aging and the implications for health


In a study published in the Proceedings of the National Academy of Sciences, the research team found that chronic stress seems to accelerate the aging process by shortening the life span of cells and opening the door to disease. The cells of people under high stress aged the equivalent of 9-17 years more than the cells of people under little stress.

The link between stress and premature aging has major implications for health. The specific cellular changes identified in this study could become a warning sign to help doctors prescribe life-extending therapies. That means that people at risk for high stress could slow cell aging through exercise, meditation, prayer, or other forms of stress reduction.
