Hyperthermia, also known simply as overheating, is a condition in which an individual's body temperature is elevated beyond normal due to failed thermoregulation. The person's body produces or absorbs more heat than it dissipates.
Hyperthermia therapy (or hyperthermia, or thermotherapy) is a type of medical treatment in which body tissue is exposed to temperatures above body temperature, in the region of 40–45 °C (104–113 °F). Hyperthermia is usually applied as an adjuvant to radiotherapy or chemotherapy, to which it works as a sensitizer, in an effort to treat cancer.
In humans, hyperthermia is defined as a temperature greater than 37.5–38.3 °C (99.5–100.9 °F), depending on the reference used, that occurs without a change in the body's temperature set point.
Core temperature is normally maintained within a narrow range so that essential enzymatic reactions can occur. Significant core temperature elevation (hyperthermia) or depression (hypothermia) over more than a brief period of time is fatal.
As temperatures start to drop around the country, some people are using space heaters to help warm up their houses. ... "Hyperthermia can result in death," she adds.
Hyperthermia can set in when the core body temperature rises above 37.5–38.3 °C (99.5–100.9 °F). [3] [4] Humans have adapted to living in climates where hypothermia and hyperthermia were common primarily through culture and technology, such as the use of clothing and shelter. [5]
Hyperthermia and other heat-related illnesses can often prove fatal, especially for older adults, ... Heat stroke occurs when someone’s body temperature increases significantly (generally above ...
Hyperthermia, also known as heat stroke, becomes commonplace during periods of sustained high temperature and humidity. [9] Older adults, very young children, and those who are sick or overweight are at a higher risk for heat-related illness. [10]
