Get Stressed , Get Old
The researchers discovered in their tests that the system of cell reproduction and replacement, which of course keeps us going, becomes faster under duress. Each time a cell in our body is replaced, part of our DNA, called telomeres, shorten. When they become too short, cells cease reproducing and our bodies continue the aging process. This means longer telomeres lengthen our lives. Stress makes them shorter, and so we die prematurely. The simple message, therefore, is to take life easy. Research leader, Dr. Elissa Epel, compared 39 women who looked after children with chronic illnesses with a ‘control’ group of 19 mothers of healthy children. The length of the life-giving telomeres was then measured in their blood. The women who had the more stressful task of caring for chronically ill children aged the equivalent of ten years compared with the other women. Their stress levels caused them to age faster. It has always been common knowledge that stress kills. Now we may soon be able to measure how dangerous our careers and lifestyles really are.
