Employees should limit the proportion of time they spend sitting while at work to 60 per cent because a lack of activity can lead to concentration problems and tension, according to a health newsletter published in Germany.

A recent edition of the newsletter, published by an organization for healthy backs, recommends office workers spend at least 30 per cent of their remaining time in the office doing something that requires they stand and 10 per cent doing something that requires movement.

Work-related pain is a typical reaction of the body to an environment for which it is not suited. Even while sitting, movement is sensible. Using a chair that has a leaning back, for example, corresponds with the natural movements of the body, and feet and legs automatically move along as well. As a result, circulation and oxygen replenishment improves to all organs, particularly the brain.

This prevents not only pain, but also helps to increase the attention span and concentration.
