Everyone likes to take a hot bath in winter, especially some citizens often take a bath for dozens of minutes, but they don't know that this is not in line with the principle of health preservation. What is there to say about taking a bath? Listen to the opinions of experts. Bathing consumes bubble feet. Why does Wenyang consume Yang when taking a bath? Luo Hongyu, an acupuncturist at Guangxi People's Hospital, explained that bathing is a yang-consuming behavior for people who are weak and tired. For example, taking a hot bath will make you sweat a lot. Chinese medicine believes that sweat is the fluid of the heart, which belongs to the vaginal fluid in the human body and cannot be damaged at will. Excessive sweating can easily damage vaginal fluid, leading to the loss of body fluid, qi and blood and yang. Taking a cold bath will stimulate the human body to transmit the viscera yang to the skin to resist the cold, and it will also lead to the excessive use of the viscera yang and overdraw the human yang. If you feel the external wind at this time, it can also cause wind-cold and wind-heat syndrome. So the bath temperature should not be too high or too low, just close to the body temperature. Besides, don't wash it for too long. Soaking feet is an act of invigorating qi. Luo Hongyu suggested soaking feet often in winter and taking less baths. As long as you persist all the year round, you can make people less sick. When will the bath water be ready? Some people like to take a bath at noon, thinking that the temperature is warmer at noon. Some people like to take a bath before going to bed in the middle of the night, thinking that they can sleep after washing, which is very comfortable. However, these two methods are not suitable for some people. Luo Hongyu said that if the yang is too weak, the most unsuitable time for bathing is in the middle of the night, that is, midnight12; The most unsuitable time for too many people in Yin Qi to take a bath is noon when the sun is strong. These two hours are just the time for the transformation of yin and yang, and a slight fluctuation of yin and yang will have a great impact on the body. In addition, many people are used to going to bed immediately after taking a hot bath. Actually, this is an incorrect habit. It is best to take a bath 2 hours before going to bed. It is best to take a bath one or two hours after meals, or you can choose to take a bath when the sun is strong in the morning. It is not advisable to take a bath immediately after cupping for extended reading. Besides massage, you can't take a bath immediately after cupping, otherwise it will easily hurt your skin and even lead to a second cold. After cupping, the skin is in a damaged state, sensitive and fragile. At this time, bathing is very likely to cause skin damage and inflammation. If the bath water temperature is too low at this time, the skin with open pores will catch cold, so you must not take a bath immediately after cupping to avoid getting sick.
