What is Hyperthermia? Hyperthermia occurs when an individual's body temperature rises above normal (98.6 degrees F) and remains there for an extended time. This usually occurs from over exertion during peak summer heat, but can also be caused by adverse effects of medication or medical conditions. Heat Stroke and Heat Prostration are common names associated with hyperthermia.

Signs/Symptoms Heat Exhaustion/ Stress Hyperthermia Early stage of Hyperthermia Heavy sweating, heat cramps, rapid breathing, fast but weak pulse Hyperthermia Hot/ dry skin, nausea, vomiting, headaches, faintness Severe Hyperthermia Confusion, hostility, intoxicated behavior, raised blood pressure, seizures, organ failure, unconsciousness, death

Causes Exertional Situational Significant physical exertion in hot conditions Insufficient water intake, consuming alcohol, lack of air conditioning Situational Mostly affects young and elderly Medications

Treatment Initial techniques for treating heat exhaustion include: Applying ice packs, spray bottle, drinking cool water, sitting in front of a fan, loosening tight clothing, moving the affected into AC Advanced Stages: Call 911

Prevention Take regular breaks when working during peak summer heat Stay hydrated Athletes should workout early morning or night if expecting hot days If traveling let yourself adjust to a new climate before exertion Avoid alcohol Consult doctor about medications which could increase risk of hyperthermia

Heat Cramp Painful contraction of voluntary muscles following vigorous exercise and profuse sweating in hot weather Core body temperature remains normal Results from loss of electrolytes via sweating Symptoms improve rapidly by replacement of water orally

Heat Syncope Syncope Temporary loss of consciousness and posture Fainting or passing out Usually occurs due to temporary insufficient blood flow to the brain

Heat Exhaustion One of the most common hyperthermic syndromes Happens with prolonged exertion in hot and humid weather, profuse sweating, and inadequate salt and water replacement Core temperature is elevated between 98.6 F to 104 F (37 C to 40 C) Symptoms will include dehydration, headache, fatigue, weakness, increasing heart rate, irritability, etc.

Heat Stroke A life threatening condition Occurs in high temperatures, high humidity, and with exertion of physical activity Core body temperature rises to more than 104 F (40 C) Pooling of blood and effected circulating blood volume is reduced

Thermotherapy Induced hyperthermia used for cancer treatment Body tissue is exposed to temperatures of 113 degrees F High temperatures damage or kill cancer cells with minimal damage to normal cells Most often used within and hour of radiation or chemotherapy
