In fact, the blood in our arteries starts from the heart and then flows to the legs and feet, which is nutritious and nutritious. Through capillaries, blood carries metabolites through venous blood and finally returns to the heart.

The blood vessels in the legs are like branches, all over the muscles and skin.

If the artery dilates, the blood flow of nutrient artery will increase; If the vein dilates, the blood flow of the vein carrying garbage will stagnate.

When your feet are soaked in hot water, the local temperature will gradually increase, the arteries will dilate, especially the skin blood vessels, the body will feel relaxed, and dopamine will be secreted, resulting in a sense of pleasure.

Although soaking feet is good, these three types of people still don't recommend soaking feet.

Being in a state of hyperglycemia for a long time will cause certain damage to the muscles, blood vessels and nerves of the human body, and make the perception of the external temperature of the legs deviate.

This is why many diabetics often feel cold in their legs. At this time, many people will choose to soak their feet with hot water to keep out the cold.

At the same time, due to the nerve injury in the leg, the human body can't sense the external temperature normally, and heating water all the time is easy to cause burns.

Once a diabetic is scalded, the wound will be difficult to heal, and it is often easy to cause infection due to ulcer, which is also the reason why diabetic patients are often prone to diabetic foot complications.

Arterial occlusion of lower limbs, mainly manifested as ischemia of lower limbs.

However, soaking feet with hot water can not increase the blood flow of normal tissues, and the oxygen consumption of ischemic tissues increases due to the increase of environmental temperature, which leads to the phenomenon of "stealing blood" and thus becomes more ischemic.

Therefore, soaking feet with hot water will aggravate the condition.

Varicose veins in the legs are mainly manifested as poor blood return in the legs, which leads to congestion in the legs, and then leads to varicose veins.

Soaking feet will only dilate blood vessels in legs and feet, and more blood will flow to legs and feet, instead of promoting reflux, which will lead to aggravation of congestion, thus aggravating the condition.
