From the perspective of Chinese medicine, this is a case of excessive body fire, usually due to hyperactivity of liver yang or deficiency of kidney qi, resulting in clinical symptoms of fear of heat. From the perspective of Western medicine, there are usually several factors: first, because of endocrine and metabolic diseases, usually due to excessive decomposition and metabolism of such diseases, such as hyperthyroidism, hyperadrenocorticism, will appear very hot clinical symptoms. Secondly, women with endocrine dysfunction and unbalanced secretion of estrogen and progesterone, such as during menopause or puberty, will also have symptoms of being afraid of heat. Third, when heat cramps, heat exhaustion and pyrexia occur during heat stroke, the clinical symptom of fear of heat will also appear.
