Sitting should disturb the natural vital functions of the human body as little as possible. Balanced sitting is based on the right (upright) position of the pelvis that is supported by the sitting bones and not by the soft tissues (such as muscles, ligaments, fat, connective tissues, blood vessels, nerves, and skin). This will result in a good back posture and in free movement of the limbs and the back.
Long-term sitting is always harmful to the body. These harmful effects can be minimized by sitting in such a way that
- the upper body is free; posture is good and tension-free
- upper and lower limbs are free to move
- thighs are pointing approximately 45 degrees downwards from the horizontal level, and the pelvis is straight
- sitting is supported by the bones in the feet, pelvis and elbows
- the genitals are not under any pressure>
The immobility involved in sitting work can be reduced by walking or stretching during phone conversations. Part of the working day can be spend standing, and on the active seats it is possible to activate the muscles in the lower back and pelvis.
Riding-like sitting in a quality saddle chair, in front of a rightly adjusted table, will cause the minimum amount of sitting-related ailments.
