Old people with dry skin are not recommended to soak their feet every day. After people enter the age of 50, the oil secreted by the skin begins to decrease, and the skin of the feet begins to become thinner. Soaking feet in hot water for a long time will not only absorb the oil on the feet, but also easily lead to cracking of the feet. People with bad blood vessels are not suitable for soaking feet, because blood vessels are bad and fragile. Soaking feet will promote the expansion of plantar blood vessels, speed up blood flow, increase the pressure of blood on the blood vessel wall, and easily cause blood vessel rupture and bleeding, so people with poor blood vessels are not suitable for soaking feet.

Soaking feet can bring comfort to human body and promote blood circulation. When soaking feet, the local temperature around our feet increases obviously, and the capillaries on the skin surface expand, which will promote the increase of arterial blood flow and bring good comfort to the body. Developing children should not soak their feet at too high a temperature. Often soaking feet with overheated water will make plantar ligaments deform and relax due to heating, which is not conducive to the development of arch, and it is easy to induce flat feet after a long time.

People with diabetes are most afraid of scalding. Diabetic foot is usually associated with diabetic patients. This is because the pathological changes of autonomic nervous system cause the loss of normal skin perspiration regulation function, skin temperature regulation function and blood supply regulation ability, which leads to the insensitivity of feet to external stimuli. So I can't test the water temperature, so I get burned easily. Moreover, high water temperature can easily lead to foot infection and accelerate the deterioration of diabetic foot. Therefore, the doctor suggested that diabetic patients should first have their families test the water temperature when washing their feet, and then let the patients put their feet in the water, and the water temperature should be 37℃.

There are many harms and no benefits. Because more arterial blood enters the lower limbs when hot water soaks the feet, it will not increase the reflux ability of veins, so for patients with varicose veins and venous thrombosis, it will aggravate blood stasis. In addition, it can also lead to capillary rupture, which is beneficial. There are reaction areas of different zang-fu organs in the body on the feet. Soaking feet will stimulate the reflection areas of the zang-fu organs, thus achieving the purpose of conditioning the zang-fu organs. Son, drunken people are not suitable for soaking feet.
