摘要

Everyone knows that stress can make you age before your time-but everyone knows is folk wisdom, not science. What science has established so far is that people under chronic stress tend to have weak immune systems and run an elevated risk of cardiovascular disease. But that doesn't necessarily prove that stressed-out people are actually aging prematurely, even if they look older than their years. But an important new study shows that folk wisdom and subjective judgment may, in this case, be right. Writing in last week's Proceedings of the National Academy of Sciences, a team of scientists reported that long-term, unrelenting stress on mothers can damage the DNA of their immune-system cells in a way that may speed up the aging process. "It's an immensely exciting result," says Robert Sapolsky, a Stanford University cell biologist who wrote a commentary accompanying the report.
