Heat is a very important concept in traditional Chinese medicine, which refers to various physiological and pathological phenomena caused by the increase of body heat or hot substances in the body. Chinese medicine believes that heat is a disease. If there is too much heat in the body, it will lead to the occurrence and development of various physical discomfort and diseases. In the treatment of traditional Chinese medicine, many diseases will involve treatment methods such as clearing away heat and toxic materials and eliminating fire. This is because Chinese medicine believes that pathogenic factors and toxins can often be taken away in the process of clearing away heat.

Besides cold and heat, heat in TCM can also be divided into excess heat and deficiency heat. Excess heat refers to excessive heat in the body, such as fever and excessive internal heat. Deficiency heat is a symptom of deficiency heat caused by imbalance of yin and yang and general weakness of the body, such as deficiency fire and night sweats. When treating diseases, Chinese medicine needs to judge the nature of heat and excess according to the symptoms of patients, so as to determine the correct treatment method.

Chinese medicine believes that heat is not only related to diseases, but also related to health care. Chinese medicine believes that spring and summer belong to the season of strong yang, which is easy to cause people to get angry, thirsty and other uncomfortable symptoms. Therefore, we should pay attention to the balance of yin and yang this season, such as drinking more green tea and eating more cold food to relieve the summer heat. At the same time, there are many cooking methods such as "moderate", "scattered", "stew" and "boil" in TCM health preservation theory, and each cooking method has its specific purpose and effect, so we should pay attention to prevent food from getting angry when cooking.
