Medical Definition of Heat-related illness Heat-related illness: A person with symptoms including headache, nausea, and fatigue after exposure to heat probably has some measure of a heat-related illness. It is important to recognize the difference between the very serious condition known as heat stroke and other heat-related illnesses. Persons experiencing any of these symptoms should consult a doctor. The heat-related illnesses include: Heat stress occurs when a strain is placed on the body as a result of hot weather. Sudden dizziness or fainting experienced after exercising in the heat. The skin appears pale and sweaty but is generally moist and cool. The pulse may be weakened, and the heart rate is usually rapid.

heat heat. 1. the sensation of an increase in temperature. 2. the energy producing such a sensation; it exists in the form of molecular or atomic vibration and may be transferred, as a result of a gradient in temperature. Symbol Q or q. 3. to become, or to cause to become, warmer or hotter.. a rise in temperature. 4. to cause to increase in temperature. Heat is associated with molecular motion, and is generated in various ways, including combustion, friction, chemical action, and radiation. The total absence of heat is absolute zero, at which all molecular activity ceases.

Heat stress â preventing heatstroke Heat stress occurs when the body becomes dehydrated and is unable to cool itself enough to maintain a healthy temperature. If left untreated, this can lead to heatstroke, which is a life-threatening medical emergency. Prevention is the best way to avoid heatstroke.

Heat-Related Illness Heat stroke is the most severe form of heat related illness. Heat stroke is severe injury from high body temperatures that causes damage to many organs, particularly the central nervous system, which include the brain and spinal cord. Heat stroke is a life-threatening emergency. Without proper care, heat stroke victims will most likely die.

Heat stroke Heat stroke, also known as sun stroke, is a severe heat illness, defined as hyperthermia with a body temperature greater than 40.6 °C (105.1 °F) because of environmental heat exposure with lack of thermoregulation. This is distinct from a fever, where there is a physiological increase in the temperature set point of the body.

Translations for heat stroke U.S. National Library of Medicine(0.00 / 0 votes)Rate this definition: Heat Stroke. A condition caused by the failure of body to dissipate heat in an excessively hot environment or during PHYSICAL EXERTION in a hot environment. Contrast to HEAT EXHAUSTION, the body temperature in heat stroke patient is dangerously high with red, hot skin accompanied by DELUSIONS; CONVULSIONS; or COMA. It can be a life-threatening emergency and is most common in infants and the elderly.

Heat Stress in the Workplace Heat Stress in the Workplace. Heat stress includes a series of conditions where the body is under stress from overheating. Heat-related illnesses include heat cramps, heat exhaustion, heat rash, or heat stroke, each with its own symptoms and treatments. Symptoms can range from profuse sweating to dizziness, cessation of sweating, and collapse.

Heat capacity Heat capacity or thermal capacity is a measurable physical quantity equal to the ratio of the heat added to (or removed from) an object to the resulting temperature change. The SI unit of heat capacity is joule per kelvin J K {\displaystyle \mathrm {\tfrac {J}{K}} } and the dimensional form is L2MT−2θ−1.

Hyperthermia (Redirected from Heat stress). Hyperthermia is elevated body temperature due to failed thermoregulation that occurs when a body produces or absorbs more heat than it dissipates. Extreme temperature elevation then becomes a medical emergency requiring immediate treatment to prevent disability or death.
