The main causes of internal heat are external evils entering the body and turning it into heat, cold evils turning it into heat, emotional disorders (emotional displeasure) turning it into heat (evils staying for too long are transformed into heat), and dietary disorders accumulating and turning it into heat.
Among them, most of them are accompanied by fever when the external evil enters the body and turns into heat. Fever is a contingent symptom of cold evils that turn into heat, of emotional disorders that turn into heat, and of dietary disorders that turn into heat. Yin deficiency internal heat is not accompanied by external sensations, usually no fever.
