In the late autumn season, many people have started a foot soaking health preservation mode, hoping to use it to recuperate their body. The reporter interviewed Wang Dong, a traditional Chinese medicine practitioner and deputy director of the Health Management Center of Jiangsu Second Traditional Chinese Medicine Hospital, and learned that soaking feet has many benefits such as dispelling cold and keeping warm, relieving fatigue, and improving sleep. However, it is not necessarily applicable to everyone. It's best to soak your feet 1-2 hours before bedtime and avoid excessive sweating... In Wang Dong's opinion, the "advice" given by these online bloggers is often only "half right". He explained that soaking feet, which seems to be a "pollution-free" way of maintaining health, also needs to be treated dialectically based on the different constitutions of different people. If a person has a Yin deficiency constitution, their Yin fluid is already relatively insufficient. These people are prone to dryness (such as dry skin, dry mouth, and dry tongue), and soaking their feet to sweat is undoubtedly harmful to Yin. However, if a person only has heavy moisture (such as white and greasy fur), soaking their feet to sweat is still beneficial. From the perspective of traditional Chinese medicine, the key to autumn and winter health preservation is to "hide", and soaking their feet does not need to blindly pursue fever and sweat, feeling comfortable. Generally speaking, healthy individuals can soak their feet in warm water, preferably with a slight sensation of warmth and sweating. The water used to soak their feet should reach the ankle and instep. But if you want to add various Chinese medicinal herbs to the water for soaking feet in order to prevent colds, relieve liver fire, warm yang and disperse cold, etc., you must consult a doctor's advice and not blindly 'add ingredients' on your own. In addition, patients with heart disease, heart failure, low blood pressure, frequent dizziness, and lower limb swelling are not recommended to soak feet because when soaking feet, the blood vessels in the feet expand and blood flow increases, Blood throughout the body will flow from important organs to the feet, causing ischemia and hypoxia in important organs such as the heart and brain, exacerbating corresponding symptoms. It is best not to soak your feet when you are hungry or full, to avoid affecting the blood supply to the stomach and causing discomfort, "Wang Dong added. (Reporter Xu Qianqian) (Xinhua News Agency)
