But Dr Jason Toniolo, Vascular Surgeon and Director of The Art of Vein Care, says while leg crossing may make veins more visible temporarily, it does not cause them to form.
“Most varicose veins are caused by faulty valves that allow blood to pool in the legs. Crossing the legs does not damage the valves.
“People with existing vein issues may feel symptoms like aching or heaviness more when they sit or stand for long periods — regardless of leg position.”
So what does contribute to varicose veins?
– Family history of venous disease
– Pregnancy and hormonal changes
– Long hours of standing or sitting
– Excess weight
– Ageing
Family history is one of the strongest predictors for varicose vein development. According to a 1994 study published in the Journal of Dermatol Surg Oncol, 90% of individuals with both parents affected by varicose veins also developed the condition, compared to only 20% among those with no family history.
While leg position isn’t a cause, symptoms like aching, restless legs, heaviness or swelling can still be telltale signs of venous dysfunction and seeking timely assessment remains important, especially for those with risk factors.
