Sitting too long makes you fat, age faster

However, more research is needed as, at this point, researchers can not tell for sure how much exercise one needs in order to counteract the effects of aging.

As we age, so do our cells. The next best thing to actually stopping the aging process, which seems impossible to do, is to slow down aging. However, the rate at which our cells die varies from person to person.

The most sedentary among them were basically eight years older biologically than their peers, based on their telomeres, they added. Genetic regulation is one such pathway. These telomeres are located at the end of a DNA strand. Shortened telomeres are associated with cardiovascular disease, diabetes and major cancers. Although shortened telomeres have been linked to certain diseases, everyone's telomeres shorten over time.

The root cause is shortening of Telomeres inside our body cell.

Sitting too much during the day has been linked to a host of diseases, from obesity to heart problems and diabetes, as well as early death.

The study was carried out by researchers from the University of California, San Diego State University, the State University of NY at Buffalo, the University of Washington, the Fred Hutchinson Cancer Research Centre, George Washington University, the University of Florida and Northwestern University, all in the US.

"Our study found cells age faster with a sedentary lifestyle".

For this recent study, researchers evaluated the link between telomere length and sedentary time in 1,481 older women with an average age of 79.

In a sample of older women, the researchers looked at whether there was an association between time spent sitting down and telomere length.

To track the women's movements in the study, they wore wore an accelerometer on their right hip for seven days in a row, during the day and night.

The scientists adjusted the results for variables such as lifestyle and health-related factors, as well as demographics and body mass index (BMI).

Researchers who assessed almost 1,500 older women found those who sat most of the day and got little exercise had cells that were biologically older by eight years than the women's actual age. The lead scientist and his colleagues found out that the cells of those who have a sedentary lifestyle are eight years older than their chronological age.

The research team believe that they are the first to objectively measure how the combination of sedentary time and exercise can affect biological aging.

Among women who didn't get the daily half hour of exercise, those who spent more time sedentary (about 10 hours or more) had shorter telomeres than those who spent less time sitting everyday. Than even as we age physical activity should continue to be a significant part of our daily lives.

Shadyab said future studies will examine how exercise relates to telomere length in younger populations and in men.
