Chronic stress can cause a wide range of medical consequances.Studies have found a link between chronic stress and a higher risk of heart attack,high blood pressure and insomnia.Stress is also associated with intense hot flushes,depression,excessive anger and hostility.Woman who were more stressed judging from subjective ratings of stress and by the duration of their care-giving had cells which showed signs of premature aging.Their telomeres, were shriveling up faster than normal.A cell cannot divide once the telomeres get too short.The longer they took care of a sick child,the shorter were the telomeres.Furthermore,women who were more stressed had lower levels of the enzyme which restores the telomere length.
