Psychological stress leads to shorter telomeres and exercise may prevent this damage, according to several studies by UCSF.
Researchers focused on three groups: post-menopausal women who were the primary caregivers for a family member with dementia; young to middle-aged adults with post-traumatic stress disorder; and healthy, non-smoking women ages 50 to 65 years.

Today, UCSF’s Elizabeth Blackburn won the Nobel Prize in Medicine. Here’s the video from the press conference held in San Francisco:
Happy New Year — is it resolution time for you? Alex Williams asked the question in today’s New York Times. Research shows that many people who try to make major lifestyle changes, like losing weight, don’t succeed. Why? They are “hard-wired not to change quickly,” said Dr. Marion Kramer Jacobs. On the other hand, Alan Deutschman, the author of “Change or Die,” says some strategies are more likely than others to bring positive results. Here are Deutschman’s four steps to success:
- Start with big changes, not small ones.
- Act like the person you are trying to become.
- “Reframe” the situation.
- Don’t do it alone.
Dr. Dean Ornish of UCSF is more optimistic. He believes that by changing your lifestyle you can change your gene expression. In fact, his studies have shown that people who are motivated to make and maintain bigger, healthier changes in lifestyle also achieve better clinical outcomes and even larger cost savings for the healthcare system.
In his recent interview with Edge-The Third Culture
, Ornish says that if stress reduces telomerase (an enzyme that repairs and lengthens damaged telomeres, which are the ends of our chromosomes that control how long we live) and makes telomeres shorter, then stress management techniques, exercise and good nutrition should be able to increase these.
Ornish later says that “the more inwardly-defined you are, the more you can quiet down your mind and body and experience more of an inner sense of peace and well being, the more empowered you are… people only have power over you if they have something that you think you need. The more inwardly-defined you are, the less you need, so the more powerful you become”. And healthier too!
