Stress Accelerates Aging. Exercise & Meditation Help.
Professor Elizabeth Blackburn is the discoverer of telomeres, tiny units of DNA at the ends of chromosomes that protect and stabilize our genetic blueprints. Telomeres seem to act as a biological clock that limits the lifespan of cells–and of ourselves.
… psychological stress actually ages cells, which can be seen when you measure the wearing down of the tips of the chromosomes, those telomeres. … We looked at the measures for cardiovascular disease — bad lipid profiles, obesity, all that stuff. The women with those had low telomerase. … Researchers have found that the brain definitely sends nerves directly to organs of the immune system and not just to the heart and the lower gut.

… mindfulness meditation techniques appear to shift cognitive appraisals from threat to challenge, decrease ruminative thought, and reduce stress arousal. Mindfulness may also directly increase positive arousal states. … meditation may have salutary effects on telomere length by reducing cognitive stress and stress arousal and increasing positive states of mind and hormonal factors that may promote telomere maintenance.
