Predominantly sedentary occupations or even sitting in class at school or university demand a lot from our backs. After some time, the musculature gets tired and can no longer keep the spine upright. Such muscle fatigue is natural, because the human body is not made to sit.
Under this point, as much movement should be brought into everyday life and work as possible. However, in certain professions, such as that of a truck driver or bus driver, it is difficult to get up and move around. But sitting in a position that is suitable for your back can prevent back pain and exercises can strengthen the muscles.
Correct sitting at the desk
Height-adjustable desks can be used to ensure correct sitting at the desk, so that each employee can adapt his or her workplace to his or her individual height. Always make sure that the desk is not too low and that you can put your elbows down easily. If the upper and lower arms are at a 90-degree angle, the desk is at a good height.
The mouse and keyboard should not be positioned too far away from your hand, otherwise you would have to bend forward too far again to reach them. More advantageous are large desks with plenty of room for your arms. The screen should not be too low and should always be at eye level so that you don’t have to bend over.
The upper edge of the screen should be at eye level. The screen should also be close to a window so that the light conditions are favourable and you don’t have to bend over to the screen to see something on it. However, the sun should not shine directly on the screen. Your desk chair should be adjusted so that your legs fit loosely under the table and the angle in your knee joint is about 90 degrees. Avoid crossing your legs when sitting and always keep them about hip-wide apart.
