1, why can I sleep better after soaking my feet in hot water?
We will find that when we soak our feet with hot water, the blood vessels on our feet will expand and the skin on our feet will turn red. This is because soaking feet with hot water will accelerate the blood circulation of the feet, make more blood flow to the peripheral blood vessels of the lower limbs, make the blood flow in the brain relatively reduce, and make people feel sleepy. At the same time, because countless nerve endings on the soles of the feet are closely connected with the brain, the warm stimulation of hot water on the nerve endings on the feet can inhibit the cerebral cortex and make people feel comfortable and relaxed in the brain, thus speeding up sleep and deepening sleep.

2. Why do you feel relaxed after soaking your feet in hot water?
Many people have the habit of doing pedicure. When a masseur massages some acupoints on his feet, he will feel pain and soreness. This situation can basically explain that there is something wrong with our corresponding visceral reflex zone. From the medical theory, all organs of the human body have reflex zones and acupoints, and there are meridians on the feet, so when we finish foot massage, we will feel relaxed all over. Moreover, soaking feet in hot water will also stimulate the acupoints, reflex zones and meridians of the feet, so we will feel very comfortable after soaking feet in hot water.

This 10 people soak their feet with hot water, which is equivalent to "chronic suicide"
Although hot water soaking feet has many benefits, it will have some adverse effects on some special people.
one
1, diabetic patients
When we soak our feet, if the water is too hot, we will instinctively retract our feet. However, for diabetic patients, because diabetes leads to microangiopathy and nerve conduction disorder, the pain fibers are damaged, and the temperature of hot water cannot be sensed in time, so they are easy to be scalded by hot water when soaking their feet. Moreover, diabetic patients' feet are not easy to heal after scalding. If they are not intervened in time, they will further develop into ulceration, infection and even foot necrosis, which is called diabetic foot.

2. Patients with heart disease
This kind of patients have weak heart function and poor blood supply ability. Soaking feet can dilate local capillaries, make blood flow to lower limbs more, make important organs such as heart and brain ischemic and anoxic, and cause discomfort such as chest tightness, shortness of breath and dizziness. In addition, blindly soaking feet in cardiovascular patients may also increase the risk of syncope and sudden death.

3, beriberi patients
Beriberi is mostly caused by fungal infection. Soaking feet with hot water will lead to secondary fungal infection, aggravate beriberi, and stimulate the skin, leading to inflammation.

4. Patients with varicose veins/thrombosis
These patients have the problem of blood reflux, especially patients with varicose veins, which are often venous valve insufficiency. At this time, soaking feet can increase local blood flow, but it can't change the speed of venous reflux, but it may increase the burden of venous reflux and aggravate the condition.

5, all kinds of severe bleeding patients
People suffering from various serious hemorrhagic diseases should not soak their feet, such as hemoptysis, hematemesis, hematochezia, cerebral hemorrhage, gastric bleeding, uterine bleeding and other visceral bleeding. When such people massage their feet with hot water, they may cause local tissue bleeding.

6, renal failure, heart failure and other critical patients.
Critically ill patients such as renal failure and heart failure, because their condition is very unstable, the stimulation of hot water on the reflex area of the foot may cause a strong reaction and complicate the condition, so such people should not soak their feet.

7. Pregnant women
Pregnant women soak their feet with hot water. If the water temperature is too high and the time is too long, it will lead to excessive blood circulation of expectant mothers, excessive burden on the heart and brain, and symptoms such as sweating, palpitation, even dizziness and collapse may occur, which is not good for the health of mothers and fetuses.

8. Developing children
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.

9. frail elderly people
Old people need to be extra careful when soaking their feet. Because more blood will rush to the lower limbs, people with weak constitution are prone to dizziness due to insufficient blood supply to the brain, and even faint in severe cases. For some elderly people with cardiovascular and cerebrovascular diseases, there is a risk of inducing stroke.

10, frozen feet cannot be hot.
The feet are frozen, indicating that they have been attacked by extremely cold and strong winds, the temperature is lower than the normal bearing capacity of the body, and the skin and muscles are in a stiff state. At this time, if your feet are suddenly scalded by hot water, the temperature will change from cold to sudden heat, and the skin and muscles will not be able to stand the huge temperature difference of tens of degrees Celsius, thus aggravating the condition of frozen feet and even making the muscles and bones peel off seriously. Therefore, when freezing your feet, you should rub them with your hands moderately to make your feet hot, instead of soaking your feet in hot water.
It can be seen that soaking feet is not suitable for everyone, although it has many benefits. Everyone should know clearly before soaking their feet, so as not to damage their health and lose more than they gain.
