Hot water washing feet

It can combine cold water, warm water and hot water.

Everyone's physique is different, and the choice of hot and cold water for bathing varies from person to person.

It is best to take a warm bath normally, the water temperature is about 30 degrees.

If you are strong, you can insist on taking a cold bath to keep fit.

If you are weak, take a hot bath, don't force it.

From a medical point of view, as long as it doesn't feel very hot, there should be no problem. But not more than 40 degrees.

The temperature of the bath water should be close to the body temperature, which is 35-37 degrees. When the water temperature is too high, the blood vessels in the epidermis of the whole body dilate, and the blood flow in the heart and brain decreases, resulting in hypoxia. Take a cold bath in summer. If the bath water is too cold, the pores of the skin will suddenly close, and the heat in the body will not be emitted because of the sudden contraction of blood vessels. Especially on hot nights, people often feel weak limbs, shoulder and knee pain and abdominal pain after taking a cold bath, and even become the inducing factors of arthritis and chronic gastrointestinal diseases. Generally, it is better to take a cold bath in summer, and the water temperature is not lower than 10 degrees.

Sweating after exercise in summer is inevitable. Many people like to take a cold bath at this time and feel very happy. However, sports experts suggest that taking a hot bath after exercise in summer is better than taking a cold bath, especially when you are sweating all over.

When pregnant women take a bath, the water temperature should not be too high to prevent fetal hypoxia and affect fetal development.

If you bathe your child with thread, you can't feel the soup with your hands. Just a warm feeling. If it is winter, use slightly warmer water, 40 degrees. You can try a bath thermometer. Your child's bath water temperature is 37-40 degrees, about 37 degrees in summer and 40 degrees in winter.

In the cold winter, taking a hot bath is a pleasure for many people. But if the water temperature is too high, not only the heart will produce high load, but also the skin will become extremely dry and the capillaries will burst.

Expert correction: there are many stresses on bathing in winter. The first is the water temperature. The suitable water temperature for bathing in winter is 37℃ to 42℃, which is 3℃ higher than human body temperature. Moreover, bathing in winter should start from the feet, because the skin temperature in winter is lower than the bathing water temperature, and the bathing water temperature in winter is higher than that in summer. Sudden hot water will bring too much load to the heart. In addition, the bathing time should not exceed 15 minutes.

In addition: scientific bathing is good for health (detailed here)

Unscientific bathing will also bring many adverse effects to the body. What are the scientific requirements for bathing?

1. Do not take a bath before and after meals: the food in the stomach has been emptied before meals, and the blood sugar of the human body is lower than the normal level. If you take a bath before meals when you are hungry, you are prone to hypoglycemia, dizziness and even fainting. Taking a bath immediately after a meal will dilate the blood vessels on the muscle surface and make the body surface full of blood, while the blood in the gastrointestinal tract will decrease and the secretion of digestive juice will be inhibited, which will affect the digestion and absorption of food. Therefore, there has long been a saying in our country that "if you don't wash, you will be hungry."

2. The water temperature should not be too high or too low: the temperature of the bath water exceeds the normal body temperature, that is, 37℃, which is called hot water bath; The temperature lower than the human body and higher than the skin, that is, 33℃, is called warm water bath. The water temperature is 34℃-36℃, which is beneficial to decontamination and itching relief; 37℃-39℃, which is beneficial to eliminate fatigue; 40℃-45℃ can relax muscles and tendons, promote blood circulation, sweat and relieve pain. The temperature of the bath water can be adjusted according to the time. For example, you can choose to take a hot bath in winter and a warm bath in summer. If the bath water is too hot and the temperature is too high, it will not only damage the skin, but also dilate the blood vessels on the skin surface, increase the blood flow on the body surface, reduce the blood supply to the heart and brain, and often lead to the danger of hypoxia and fainting.

In summer, some people, especially teenagers, like to take a cold bath when they just stop activities or exercise and are sweating all over. Actually, it's easy to catch a cold and get prickly heat. We advocate taking a warm bath in summer, because warm water will not cause skin blood vessels to contract, and sweat glands can be kept unobstructed.

3. Bathing time: Bathing time should not be too long, especially for children. Generally, it should not exceed half an hour. Soaking for too long will aggravate fatigue and cause dizziness.

4. Choice of bathing methods: Bathing methods are divided into shower, tub bath and pool bath. And the shower is the most sanitary, especially for women. When men take a bath in the bathroom pool, they should not soak in the bath for too long. After cleaning, it should be washed with clean warm water. You can use soap or medicated soap when taking a bath, avoid using laundry soap or washing powder, and finally rinse your skin with clear water. Don't leave soap bubbles on your skin.

When taking a bath, use soap and shower gel in the palm of your hand and rub the whole body skin from bottom to top, which is called friction bath. Bottom-up reverse friction can play the role of massage and health care, which can not only remove dirt on the skin surface, but also help the skin and muscles to relieve fatigue, promote blood circulation of the skin, enhance the respiratory function of the skin, and relieve and delay wrinkles caused by downward relaxation of the skin. Don't rub too hard in the shower, the skin surface is slightly red. Avoid rubbing the skin with hard towels and other items to avoid scratching the epidermis.
