Sitting too much is one of the worst things you can do to your body. Watching whole seasons of your favorite show may sound like the perfect Friday night, but you’re putting your health at risk after just a couple of episodes. You are literally sitting yourself to death. More than 11 hours a day in this crunched position, increases risk of premature death by 40 percent. A study that looked at more than 4 million individuals and 68,936 cancer cases concluded that sitting for long periods of time increases your risk for colon, endometrial and possibly, lung cancer. Aside from the gym, your home is where you can freely work out. Physical activity reduces the risk of backaches, stiffness, headaches and many chronic diseases.
