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.
What are telomeres? Answer. Telomeres, the ends of the arms of chromosomes of eukaryotes, become shorter as organisms age. They are thought to act biologically to slow chromosome shortening, which can lead to cell death caused by the loss of genes and may be related to aging and diseases such as cancer.
