Reduced Sitting Time = Telomere Lengthening
An interesting study in 2014 out of Uppsala University in Sweden showed that, independent of increased physical activity, reducing sitting time resulted in increased telomere length. The study measured telomere length in blood cells of 49, 68 year old, sedentary, overweight individuals. After a 6 month physical activity intervention researchers found that telomere lengthening was only significantly associated with reduced sitting time. Clearly more study with larger groups is warranted, but evidence is mounting that simply standing more than sitting in your day pays significant health dividends.
