Researchers in the US estimate that less than three hours of sitting down in a day could add up to two years to a person’s life.

Cutting down time for other sedentary activities like TV watching could also add a couple of years to one’s life.

These results are based on a study of 167,000 people, who were asked how many hours a day they spent sitting down or watching TV. Using the answers, researchers analyzed people’s health risks and life expectancy.

But some experts say the results of the study are not very reliable because the data came from people’s recollection of how much time they spent sitting and may not be accurate. The research was also limited to only a sample of the American population.

Additionally, the subjects’ different lifestyles were not taken into account. There may have been some subjects whose poor health causes them to have sedentary lifestyles and not the other way around.

The researchers themselves admit their findings are just educated guesses, but they say the study could be used as a health warning to the public.

Natasha Stewart, a senior nurse from the British Heart Association, says that although the US study does not prove sedentary activities directly shorten lives, the study emphasizes people’s need to have more active lifestyles to prevent getting diseases that put people’s live at risk.
