Why is soaking feet very comfortable? Let's talk about the knowledge of blood vessels in human lower limbs first. 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. The blood vessels in the legs are distributed 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 venous blood carrying garbage will stagnate. 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 generally comes from this.
Soaking feet with hot water is harmful to patients with varicose veins and venous thrombosis. When the feet are soaked in hot water, the arteries of the lower limbs dilate, especially the skin is congested, and 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.
Soaking feet makes diabetic foot patients face amputation. Diabetic foot can be divided into three types: neuropathy, ischemia and mixed type. Some patients with neuropathy can show that their legs and feet feel particularly cold and are afraid of cold. Therefore, hot water soaking feet can easily become a comfortable choice. Tragically, once neuropathy exists, the patient's sensory feedback mechanism for pain and water temperature fails.
Therefore, patients often keep boiling water, even if they have been severely burned, they are unaware of it. The problems faced by patients with ischemic diabetic foot are similar to the "arterial occlusive disease" mentioned above. Therefore, if you have lower extremity arterial occlusive disease and diabetic foot, soaking your feet in high temperature will lead to amputation! Knowing these reasons, I suggest you find out whether you have the above vascular diseases before soaking your feet; If not, you can rest assured to enjoy it.
The best time to soak your feet is 9 pm, because this is the time when the kidney meridian is weak in qi and blood. At this time, soaking feet, the blood vessels in the body will expand after the body heat increases, which is conducive to promoting blood circulation and promoting blood circulation in the body. At the same time, the nerves that have been nervous for a day and the kidneys that have been tired for a day can be completely relaxed and fully adjusted by soaking feet at this time to achieve the best effect of nourishing the kidneys, and people will feel very comfortable.
It is no problem for healthy people to soak their feet in hot springs, but special people should pay attention. For example, patients with heart disease and cardiac insufficiency, people with low blood pressure and frequent dizziness should not soak their feet with too hot water or soak in hot springs for a long time.
