Sitting disease is a condition where a person spends most of his time sitting, such as at a sedentary office job, explains WebMD. This leads to too much "screen time," which is time spent in front of a computer, television or mobile device. An overabundance of screen time has been linked to health problems, according to Wikipedia.
Wikipedia also notes that health risks are especially high in those that sit for more than five hours per day. Those who sit for long periods but also exercise more than four hours per week have been shown to remain healthy.
WedMD cites James Levine, M.D., author of "Move a Little, Lose a Lot," as stating that it's strange that so many people are now spending all day in a chair. He considers this a form of physical entrapment. He believes that the human body needs exercise in order to remain healthy.Learn more about Exercise
