“Fire” is not a medical concept, but is related to the heat syndrome in Chinese medicine, which may be related to dietary factors, emotional and emotional disorders, irregular work and rest, and spleen deficiency in spring. Such as long food, spicy food may lead to gastric fire (stomach fire and heat of the evil exuberance), mouth and tongue sores, thirst and dry mouth and so on. 1. Dietary factors: If you eat for a long time, eat spicy food, or take pungent and warm medicines for a long time, it may lead to exuberant fire in the stomach, sores on the mouth and tongue, thirst and dryness of the mouth, and a preference for cold drinks. 2. Emotional disorders: Chinese medicine believes that spring corresponds to the liver. It is easy to have liver problems, such as emotional upset, leading to stagnation of qi, depression and fire, the liver and gallbladder fire, head swelling and pain, burning pain in the ribs and abdomen. 3. Irregular work and rest: If you stay up late for a long time and overwork, you can damage the yin and fluids in your body or have yin deficiency, resulting in yin deficiency, leading to deficiency heat, which can lead to heat in the hands and feet, hot flashes (a burst of heat), night sweats (abnormal sweating after going to sleep, and sweating stops after waking up), and so on. 4. Spleen deficiency: If the spleen qi is insufficient and cannot transport water and dampness, it can lead to the prevalence of dampness and heat, resulting in dampness and heat, leading to heavy limbs, constipated or sticky stools, dry mouth, etc. If there is heat in spring, it is recommended to ask the doctor about the symptoms of dampness and heat. If heat evidence appears in spring, it is recommended to ask the doctor and make a clear diagnosis under the doctor’s guidance and in combination with systemic symptoms.
