Since the 1950s, the number of office jobs has increased by 83%. At the same time, the number of physically active jobs have decreased from 50% in 1960 to less than 20% now. Although it seems harmless, sitting is harmful for us.

Since the 19th century, the number of office jobs have steadingly increased. Although office jobs are generally safe, the prolonged sitting is bad for us. Prolonged sitting puts pressure on our spine and the tissue surrounding our thigs. After a couple of hours of sitting, our blood flow is redued and our digestion slows down. The reduction in blood flow means that our brain does not get as much oxygen and our heart has to work harder leading to an increased risk to get a heart attack. Also type 2 diabetes, dementia and Alzheimers are associated with prolonged sitting. Even young adults can suffer direct consequences from prolonged sitting as the pooled blood in the legs might lead to thrombosis. Prolonged sitting is also associated with various forms of cancer in men and women.
In order to counterackt the negative effects of prolonged sitting we might try some aerobic exercises. Although they generally help with obesity and blood pressure, scientists have found that sports does not completely compensate for the negative effects of prolonged sitting. This is why there are now alternative options to support a more active lifestyle. Standing desks are a viable option as they can alleviate some but not all side-effects of prolonged sitting. Treadmill desks at work have also shown some benefits. But the easiest solution would be to take a break from time to time, stand up and move.
