3. 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.

4. 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

5. 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

6. 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

7. 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

9. 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

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

11. 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.

12. 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

Experienced hyperthermia symptoms
Heat stroke in Mankato, MN
Multiple organ failure and body temperature of 108

14. 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
