Is it better to wash your face with cold water or take a bath with hot water? To put it simply, taking a cold bath has three advantages. First, it increases the adaptability of human body to temperature, especially to cold air, and it is not easy to catch a cold. Second, it is good exercise for human blood vessels. When taking a cold bath, the blood vessels contract rapidly, and a large amount of blood flows to the inside of the body and then to the body surface. In the long run, blood vessels can be prevented. Can exercise people's will. It's pleasant to take a bath in summer, but it takes perseverance to take a cold bath in winter. Disadvantages: Different personal constitutions will lead to different diseases. Precautions for taking a cold bath ... In summer, many people take a bath every day, often taking a cold bath to save trouble, and some people take a cold bath for health and fitness. Cold water bath has many functions. For the panel, it can make the blood vessels contract first and then expand, improve the efficiency of blood circulation, enhance the nutrition of the panel, make the subcutaneous tissue accumulate a certain amount of fat, and make the panel look young and elastic, so that panel diseases are not easy to occur. Cold water bath can exercise the temperature-sensitive nerve receptors on the panel and eliminate abnormal sweating. For the whole body, cold water bath can improve the body's rapid adaptability to cold, and it is not easy to suffer from cold-induced diseases such as cold, bronchitis, tonsillitis, pneumonia and allergic rhinitis. Cold water bath promotes blood circulation between viscera of panel. The expansion and contraction of blood vessels exercise the elasticity of blood vessels, which can prevent arteriosclerosis and its diseases, such as coronary heart disease and hypertension. Cold water bath increases the blood flow of visceral blood vessels, including digestive tract blood vessels, thus strengthening the function of digestive system. When cooling with a cold water bath, it is not advisable to suddenly immerse in cold water at first. It is best to splash some cold water on your body with your hands or shower head, or wet your hands and feet with cold water first, and then wet your chest and back with a towel. Rub your body for a while, cold water will soak you through and dry quickly until your skin turns red, which means the effect is good. If you feel cold, you should shorten the shower time or raise the water temperature. The following kinds of people should not take a cold bath. (1) Hypertensive patients: When the panel touches cold water, the blood vessels contract sharply, and a large amount of blood rushes back to the internal organs, making the already high blood pressure higher. In severe cases, it can cause cerebrovascular rupture, bleeding, stroke, coma and even death. People with slightly elevated blood pressure can take a cold bath, but only slowly, that is, sprinkle some cold water first and rub some parts of the body instead of "cold treatment" at once. (2) Patients with sciatica and arthritis: After the nerves catch cold, the condition will be more serious. (3) People who are allergic to cold, such as patients with cold urticaria and facial itching, should not take a cold bath during the onset. If you want to exercise the panel when you don't have an attack, it is feasible to gradually cool down, that is, take a hot bath at first, gradually switch to a warm bath, and then gradually lower the water temperature until the water temperature is quite low but you don't get sick.

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 panel 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.

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 panel 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 temperature of the panel in winter is lower than that of the bath water, and the temperature of the bath water used 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; It is called warm water bath, which is lower than human body temperature and higher than panel temperature, that is, 33℃. 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 panel, but also dilate the blood vessels on the surface of the panel, increase the blood flow on the body surface and reduce the blood supply to the heart and brain, which often leads 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 vasoconstriction of the disk, 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. Do not use laundry detergent or washing powder. Finally, rinse the panel with clean water. Don't leave soap bubbles on the panel.
When taking a bath, put soap and shower gel in the palm of your hand and rub the whole body panel from bottom to top, which is called friction bath. Bottom-up reverse friction can play a health care role, which can not only remove the dirt on the surface of the panel, but also help the panel and muscles to relieve fatigue, promote the blood circulation of the panel, enhance the respiratory function of the panel, and alleviate and delay the wrinkles caused by the downward relaxation of the panel. Don't rub the shower too hard, the surface of the panel is slightly red. Avoid rubbing the panel with hard towels and other items to avoid scratching the epidermis.
