The condition of a temperature-regulating animal when the core temperature is more than one standard deviation above the mean core temperature of the species in resting conditions in a thermoneutral environment.
The therapeutic application of heat, either locally, regionally, or systemically, based on the belief that tumors have a lower tolerance to heat than do healthy tissues. Ultrasound, radio-, and microwaves are among the techniques used in this process.
"Hyperthermia is a treatment that uses several different methods for increasing the temperature of the area of the body containing cancer. The combination of radiation therapy and hyperthermia is more effective than radiation therapy alone in treating some types of cancers," Quote from American Cancer Society.
A type of treatment in which body tissue is exposed to high temperatures to damage and kill cancer cells or to make cancer cells more sensitive to the effects of radiation and certain anticancer drugs.
Overheating of the body. This may be due to extreme weather conditions. Unrelieved hyperthermia can lead to collapse and death, particularly in the elderly. Prevention via air conditioning, ventilation, and drinking extra water is the key for vulnerable persons. In emergency cases, injections of saline solution and rapid cooling of the body may be needed. Also known as heatstroke or heat prostration.
Hyperthermia (hyperpyrexia), in its advanced state referred to as heat stroke or sunstroke, is an acute condition which occurs when the body produces or absorbs more heat than it can dissipate. It is usually due to excessive exposure to heat. The heat-regulating mechanisms of the body eventually become overwhelmed and unable to effectively deal with the heat, and body temperature climbs uncontrollably.
