People who suffer severe and chronic depressions age sooner, according to a new study.
The team of researchers in California and the Netherlands noticed people with depression have shorter telomeres than their healthy peers. Telomeres are strands of chromosome caps that shorten as people age. The study was published in the journal Molecular Psychiatry on Nov. 12, 2013.
Based on these measurements, the researchers found that those who are clinically depressed for 2 years abnormally aged 7 to 10 years. Also, people who experienced the most severe depression had the shortest telomeres.
According to the study, while depression tends to induce harmful lifestyle habits—such as drinking, smoking, taking drugs—that shorten people’s lifespans, depression itself is also responsible for premature aging. Even though the researchers can’t confirm a direct correlation between depression and aging, psychological distress does take a toll on the body.
