From the point of view of traditional Chinese medicine, red hands and sweating are manifestations of yin deficiency, so it is necessary to nourish yin to solve the problem of red hands and sweating. Cold hands and feet are due to spleen deficiency and qi deficiency, which can not promote blood circulation, and blood circulation in hands and feet is slow. This situation of yours is mostly due to spleen deficiency and qi deficiency caused by yin deficiency, so it is necessary to nourish yin and clear heat, supplemented by invigorating spleen and benefiting qi, so as to gradually solve the problem. Don't eat cold and spicy food in your diet, so as not to hurt your spleen, qi and yin. In the afternoon, you can eat watermelon to nourish yin and reduce fever, which will gradually solve your problem of yin deficiency. Eat cooked yam, coix seed, peanuts, potatoes, sweet potatoes and other foods that strengthen the spleen and replenish qi on weekdays, so that your hands and feet are not easy to catch cold. Then drink Ophiopogon japonicus water (Radix Rehmanniae 15g, Ophiopogon japonicus 15g) every day to solve the problem of yin deficiency, and your hands will not sweat. However, I suggest you find a good Chinese medicine doctor to adjust carefully. After all, a little detail can reflect the imbalance of the human body. I suggest you find a good Chinese medicine practitioner to carefully demonstrate the adjustment. This is my answer to your question. Thank you.
