It is important to raise awareness of the risks of prolonged sitting. Nowadays, it is well-known that too little physical activity has detrimental health effects, but people are less familiar with the risks of too much sitting. Recent studies show that sedentary behavior – defined as activities with low energy expenditure which involves sitting or reclining-  is a health risk factor as well. Independent of the amount of physical activity, sedentary behavior is associated with obesity, metabolic syndrome, diabetes, cardiovascular disease, and mortality. By limiting prolonged sitting by standing up more often, the risks of sitting can be reduced. Instruments need to be developed which can monitor sedentary behavior and can provide real time feedback to encourage people to stand up more often. Guidelines need to be developed about how often and how long people should interrupt sitting during the day, but for now the advice is to move more and sit less!
