Long-term complications of standing

The long-term complications of standing are the conditions that may arise after prolonged time in standing position. To maintain health while standing, one should maintain Neutral Spine.



In contrast to proper posture or "Neutral Spine," "slouching" refers to improper posture or "non-neutral spine."

While a shift of weight from one foot to another to alleviate the strain of long-term standing poses no harm, a slouching posture is able to optimally distribute weight across the body framework. Since it is a posture of unconstant, static strain on the muscles involved it causes increased alertness. Secondarily, it can also cause varicose veins.

2.Varicose veins

Varicose veins are veins that have become enlarged and twisted.

Just as with orthostatic hypotension, gravity pulls the blood downwards to the lower part of the body. Body mechanisms, such as vasoconstriction and valves of the veins, on the other hand, assist in forcing blood upwards. However, the valves of the veins work best in concert with accompanying muscle contractions. Standing with some muscles constantly strained, on the other hand, such as in slouching, creates no support for the system carrying blood upwards. As a result, the veins in the legs might become distended, making the valves unable to close properly, causing further distension and thus varicose veins.

3.Joint compression

Standing results in a state where there is pressure on e.g. the synovial joints, e.g. the knee, but without any significant movement of it. Therefore, the bones squeeze the synovial fluid to the sides, in contrast to the case in dynamic pressure, which permits the fluid to circulate. Thus, long-term standing reduces the normal lubrication and cushioning of synovial joints, causing tearing of them.

4.Postural muscle fatigue

The muscles need rest between periods of strain. Constant standing never gives them this opportunity. Eventually they’ll become exhausted, which can be felt as pain.

Risk factors

Pregnancy is a risk factor, both for the mother and the child. Walking or standing more than six hours per day has been linked with pre-term births, low birth weights as well as high blood pressure for the mother.

Further complications

Suffering people may be less alert in their tasks, resulting, e.g., in incidents at work.


A well-designed and ergonomic workplace helps, such as by allowing workers to sit when necessary.
