Scientists have found that sitting down for more than 3 hours per day cuts about 2 years off your life expectancy. Watching TV for more than 2 hours per day will cut another year off your life expectancy. Researchers say inactivity cuts about as many premature deaths as smoking does every year.
There is also a distinct difference between exercise and keeping active all day. So, you may exercise for up to an hour a day but still find yourself sitting down for long periods. Dr. Jack Der-Sarkissian says that by being physically active, people enhance their muscles and release hormones that activate metabolism and reduce inflammation. People who are active meaning those who move around periodically throughout the day seems to encourage health and a longer life.
According to the study, lack of activity can worsen the risk for breast and colon cancer, type 2 diabetes and heart disease. People who are sedentary tend to experience weight gain which is normally abdominal fat. People who work in an office which involves a lot of sitting down can find it more difficult to exercise. But just getting up every 20-30 minutes and moving around can make a huge difference to your physical activity levels.
Der-Sarkissian advises people “Do not park yourself in front of a computer, or at your desk, or in front of the TV,” he said. “Do not make that part of your norm. Your norm should be standing, and you should be as active as possible.”
