       You’ve most likely heard the news by now: A car-commuting, desk-bound, TV-watching lifestyle can be harmful to our health. All the time that we spend rooted in the chair is linked to increased risks of so many deadly diseases that experts have named this modern-day health epidemic the “sitting disease.” '
       Sitting for too long slows down the body’s metabolism and the way enzymes break down our fat reserves, raising both blood sugar levels and blood pressure. Small amounts of regular activity, even just standing and moving around, throughout the day is enough to bring the increased levels back down. And those small amounts of activity add up—30 minutes of light activity in two or three-minute bursts can be just as effective as a half-hour block of exercise. But without that activity, blood sugar levels and blood pressure keep creeping up, steadily damaging the inside of the arteries and increasing the risk of diabetes, heart disease, stroke, and other serious diseases. In essence, fundamental changes in biology occur if you sit for too long. 
       But wait, you’re a runner. You needn’t worry about the harm of a sedentary lifestyle because you exercise regularly, right? Well, not so fast. Recent studies show that people spend an average of 64 hours a week sitting, whether or not they exercise 150 minutes a week as recommended by World Health Organization (WHO). Regular exercisers, furthermore, are found to be about 30 percent less active on days when they exercise. Overall, most people simply aren’t exercising or moving around enough to counteract all the harm that can result from sitting nine hours or more a day. 
       Scared straight out of your chair? Good. The remedy is as simple as standing up and taking activity breaks.
