Dr. Lee, a researcher in the department of epidemiology at the Harvard School of Public Health, recently published a study in British Medical Journal showing sitting down for over three hours a day can cut life expectancy by two years, even if you’re a physically active non-smoker. The estimated gains in life expectancy in the US population were 2.00 years for reducing excessive sitting to < 3 hours a day and a gain of 1.38 years from reducing excessive television viewing to < 2 hours a day.
