“Hyperthermia” is derived from the Greek words “hyper” and “therme,” meaning “hyperpyrexia” or “overheating.” It is one of the physiotherapies that take various thermal sources as media to spread heat throughout a human body for therapeutic purposes. There are three common hyperthermia methods: highfrequency diathermy, radiant heat therapy, and conductive heat therapy. In traditional Chinese medicine (TCM), hyperthermia is a branch of external therapy of Chinese medicines, which includes stone needle, burning acupuncture, medical fumigation, medicated bath, hot wax therapy, moxibustion, etc. In modern medicine, hyperthermia makes use of not only various media to transfer heat to the human body through transmission modes such as conduction, convection, and radiation, but also the electromagnetism principle that allows the human body to absorb energy in the electromagnetic field and convert it into thermal energy.
