Heat stroke is a form of hyperthermia, not to be confused with hypothermia. While both conditions are a system failure to control the body’s internal temperature, hyperthermia has to do with an increase in temperature, 104 degrees Fahrenheit or more. Heat-related illnesses, such as heat stroke, do have similarities to hypothermia in that they are often accompanied by changes in the nervous system and involuntary physical symptoms. Unlike other heat-related illnesses, however, heat stroke is a medical emergency that requires immediate intervention.

Through normal bodily functions, you are typically able to dissipate excess heat through the radiation of heat through the skin. Unfortunately, on hot days or under extreme circumstances, your body cannot eliminate excess heat fast enough, which can result in a temperature in excess of 104 degrees Fahrenheit. When this happens, your body begins exhibiting potentially dangerous signs and symptoms. It is necessary to know those symptoms so you are prepared if you or someone around you experiences this condition.

1. Increased Body Temperature

The major sign of heat stroke is an increased body temperature. The average body temperature typically fluctuates between 97.7 and 99.5 degrees Fahrenheit. However, during hot, humid days, that temperature can steadily increase, especially if you are out in the sun for prolonged periods. Typically, people should get concerned about their temperature when it reaches between 99.5 and 100.9 degrees Fahrenheit, because that indicates a fever.

People who are suffering heat stroke can have a temperature of greater than 104 degrees Fahrenheit. Temperatures of that range are considered severe hyperthermia, and once the body reaches this temperature, it is critical for the patient to seek medical attention. Heat stroke is more severe than other heat-related illnesses; it is dangerous and can be deadly if left untreated, so beware and understand that your body has temperature limits.
