The habit of sitting with one leg crossed over the other has long been considered harmful. However, modern research shows that for most people, it poses no danger. This is reported by The Conversation.
Scientists note that there is no convincing evidence of harm from this position: it does not damage the spine and does not lead to wear of the hip or knee joints. The key factor is not the position of the legs, but prolonged periods of immobility.
The notion of 'correct' seating has developed from outdated norms of discipline and posture, which over time have come to be perceived as medical recommendations. The discomfort that arises from sitting with crossed legs for a long time is explained by the body's signal to change position.
Research has not found a universal 'ideal' sitting position: the spine is capable of adapting to different positions. The same goes for the joints. The fact is that they experience significantly greater stress when walking and running, so a temporary change in their position is not associated with the development of diseases.
The connection with varicose veins is also not confirmed: the disease develops due to dysfunction of the venous valves and depends on age, heredity, pregnancy, excess weight, and prolonged standing. In some cases, doctors may temporarily recommend avoiding this position, for example, after surgeries or in the presence of localized pain.
Experts believe that the main importance lies in regularly changing positions and movement. It is the variety of positions and moderate physical activity that are more important than attempts to constantly sit 'perfectly.'
