Sabrina Islam, MD, MPH, Associate Professor of Medicine at the Lewis Katz School of Medicine at Temple University, provided perspective for a PhillyVoice article about a study published in the International Journal of Epidemiology which found that people who sit for more than 10 hours a day have higher risks for cardiovascular and circulatory diseases. The study also found that standing for long periods was not linked to a higher risk for cardiovascular disease but may increase the risk for circulatory diseases. Dr. Islam offered insight on what makes a sedentary lifestyle so detrimental and how to combat that effect.
