| Exercise Makes Your DNA Younger! |
| Here's why it adds years to your life |
We know that regular exercisers have lower rates of heart disease, type 2 diabetes, high blood pressure, obesity and osteoporosis --- all good things. But recent research is indicating that an active lifestyle may actually lead to changes in your DNA that may actually make you biologically younger than those your chronological age. How cool is that?
Researchers in London studied 2,301 Caucasian twins, using both questionnaires and blood samples. Examining the length of telomeres (sequences at the end of DNA chromosomes which we know shorten progressively over time) they found that those who were more active during their leisure time had longer telomeres that those were less active.
The most active people, who were getting exercise about 3 1/3 hours per week, aside from activity at work, had the same length telomeres as people years younger, on average. Researchers speculate that physical activity may reduce the physical effects of psychological stress as well as reduce the effects of inflammation.
TAKE AWAY KNOWLEDGE: While future research may find other factors that effect telomere length related to people who are active versus people who are sedentary, researchers feel regular exercise is a proven benefit to your health and that it may even keep you biologically younger at a basic, biological level.
