Chronic stress accelerates premature aging by shortening DNA telomeres. A wide range of studies have shown that the stress caused by things like: untreated depression, social isolation, long-term unemployment, anxiety attacks... can speed-up the aging process by shortening the length of each DNA strand.
Although telomeres usually shorten with age, they can lengthen through the action of an enzyme called telomerase. Iiris Hovatta of the Research Program of Molecular Neurology at the University of Helsinki, who was not involved in the Romanian study, suggests that shortened telomeres might not be permanent.
