The common cause of hot hands and feet in summer, especially the heart of the hands and feet, may be a normal physiological response to the hot weather, but also may be caused by summer heat injury to the yin. 1. In summer, the weather is hot, the external environment temperature is high, the appearance of hands and feet fever is a normal physiological reaction, such as no other symptoms, can not do special treatment. 2. The climate in summer is characterized by high summer heat and sweating, which can easily injure fluids and deplete vital energy. Those who do not have enough yin fluid are prone to yin deficiency, which is manifested by symptoms such as heat in the hands and feet, heartburn and hot flashes, and dry mouth. In summer, if there is excessive sweating, heat in the hands and feet, low-grade fever, or night sweating (abnormal sweating after going to sleep, but sweating stops after waking up), Sheng Wei Drink can be used to astringe yin to stop sweating (astringing yin fluids to minimize sweating), and to benefit qi to generate body fluid (promoting the production of body fluid by tonifying qi). This formula contains three herbs: ginseng, maitake, and schizandra. Ginseng promotes the production of fluid and vital energy, maitake replenishes yin fluid, and schizandra restrains sweating, making it a common formula for health care in the summer. However, this formula is not suitable for spleen and stomach deficiency and various solid cold cases. In summer, if there is any discomfort in the hands and feet, if you need to use Chinese medicine to regulate, it is recommended to use it under the guidance of a professional Chinese medicine practitioner, and do not use the medication at will on your own.
