The blood in the artery starts from the heart and flows to the legs and feet. It is rich in nutrition and oxygen. Through capillaries, blood carries metabolites (garbage) through venous blood and returns to the heart.
When soaking feet, the local temperature rises, which will lead to arterial dilation, especially skin blood vessels. The saying of "promoting blood circulation and removing blood stasis" comes from this.
Soaking feet-a disaster for patients with thrombosis
In the vascular clinic, we often meet patients with vascular diseases who are miserable because of soaking their feet. I don't blame patients and their families, because patients with vascular diseases of lower limbs often feel cold in their lower limbs and naturally think of hot water to soak their feet. Then why did it backfire?
Soaking feet with hot water is harmful to patients with varicose veins and venous thrombosis. What kind of process is this?
When the feet are soaked in hot water, the arteries of the lower limbs dilate, especially when the skin is congested, more arterial blood enters the lower limbs; However, the reflux capacity of vein will not increase. Therefore, for patients with venous diseases with poor reflux or obstruction, soaking feet with hot water will aggravate blood stasis.
In addition, soaking feet in hot water can also cause capillary rupture and form bleeding spots on the skin. After a long time, pigmentation will form and the color of the calf will turn black.
If patients with venous thrombosis are taking anticoagulants, the bleeding will be more serious.
Remind everyone to understand.
