The negative impacts of a sedentary lifestyle, as well as the chronic impacts of sitting for 40 hours or more a week at a desk are well documented. New research indicates that reversing this damage can potentially be as easy as taking an extra 2 minute walk every hour. Published in the Clinical Journal of the American Society of Nephrology, investigators founds that replacing 2 minutes/hour of sedentary activity with 2 minutes/hour of walking decreased the risk of death by 33% in the general population.
Over the course of 3 years, the study observed over 3500 subjects, finding that the equivalent of adding an extra 2 minutes an hour of walking was enough to significantly decrease the risk of death. Srinivasan Beddhu, MD, out of the University of Utah and lead author on the study indicated that the intensity of the hourly activity would need to be light-intensity activity such as walking, versus low-intensity activities such as standing.
This research is even more impactful with individuals with chronic kidney disease (CKD), of which over 10% of the sample population had the disease. The “trade-off” of sedentary activity with light-intensity activity was found to decrease the risk of death by 41% in subjects with CKD. “Sitting for a long time strongly increases the risk of death. Our findings suggest that replacing sedentary duration with an increase in light activity might confer a survival benefit,” said Dr. Beddhu.
