Healthy lifestyle may buffer against stress-related cell aging, study says
Date:7/29/2014

A new study from UC San Francisco is the first to show that while the impact of life's stressors accumulate overtime and accelerate cellular aging, these negative effects may be reduced by maintaining a healthy diet, exercising and sleeping well.

"The study participants who exercised, slept well and ate well had less telomere shortening than the ones who didn't maintain healthy lifestyles, even when they had similar levels of stress," said lead author Eli Puterman, PhD, assistant professor in the department of psychiatry at UCSF. "It's very important that we promote healthy living, especially under circumstances of typical experiences of life stressors like death, caregiving and job loss."

The paper will be published in Molecular Psychiatry, a peer-reviewed science journal by Nature Publishing Group.

Telomeres are the protective caps at the ends of chromosomes that affect how quickly cells age. They are combinations of DNA and proteins that protect the ends of chromosomes and help them remain stable. As they become shorter, and as their structural integrity weakens, the cells age and die quicker. Telomeres also get shorter with age.

In the study, researchers examined three healthy behaviors physical activity, dietary intake and sleep quality over the course of one year in 239 post-menopausal, non-smoking women. The women provided blood samples at the beginning and end of the year for telomere measurement and reported on stressful events that occurred during those 12 months. In women who engaged in lower levels of healthy behaviors, there was a significantly greater decline in telomere length in their immune cells for every major life stressor that occurred during the year. Yet women who maintained active lifestyles, healthy diets, and good quality sleep appeared protected when exposed to stress accumulated life stressors did not appear to lead to greater shortening.
