Now scientists have said they could be perfectly safe habit to sit all day long for the human health. Only for this, every half an hour to get up and warm up. The way you sit, your health is more important than the total amount of time spent in a sitting position. If adults spend in this position from 9 to 10 hours during the day, it increases the risk of cardiovascular disease, and even premature death. Experts point out that to counter this risk need short bursts of physical activity, that is, people need to get up from a chair or couch every half hour. These conclusions were reached after the researchers compared the amount of time that people spend in a seated position during the day, as well as their level of mortality. The results showed that the people who get up every half hour and move significantly less likely to face the risk of premature death compared with those who spend in a seated position, a long stretch of time. These findings by researchers from Columbia University made on the basis of observations of 7985 adults over 45 years old. In particular, we show that adults who sit for one to two hours without lift, have a greater risk of premature death compared with those who spend in a seated position is exactly the same time, but it regularly arises. In this regard, the researchers call for stop to take a sedentary lifestyle only the total amount of time that people spend sitting. It is necessary to clearly distinguish between those who constantly gets up and warming up, and those who sit all at the same time, not bothering to lifts. On average, accounted for 77 seats % waking period of study participants, representing more than 12 hours a day. During the observation period, which will continue for 4 years, 340 volunteers died. The risk of mortality was calculated on the basis of the total time spent in a sitting position, as well as how often people got up and warming up.
