Spending less time sitting and fewer hours in front of the television means a longer life, according to new study conducted at the US Pennington Bio-medical Research Centre in Louisiana. People who sit for fewer than three hours a day on average could increase their lifespan by as much as two years, reported the study in the British Medical Journal.

And fewer than two hours per day spent watching television lengthens lives by around 1.4 years. The outcomes indicate that long periods of sitting and watching television are cutting the life expectancies of the American population, according to a press release issued by the team, which evaluated data from the US National Health and Nutrition Examination Survey (NHANES), a databank on US lifestyles.

Additional US studies taking in a total of 167,000 adults were used to compile data on the amount of time spent sitting and causes of death of all kinds. Analysis of these studies provided an indication of the consequences of a sedentary lifestyle on longevity, but the results should be treated with caution, researchers said, adding that the conclusions drawn were purely theoretical and failed to take into account differences in the various age and population groups.

The analysis was based on data on sitting and television time provided by the subjects, implying that false information could have contaminated the study. The NHANES data indicate that adults spend 55% of their day sitting on average. They called for a marked behavioral change to secure noticeable increases in longevity.
