THERMOREGULATION, preservation of the normal body temperature, is well developed in humans, and monitoring the body temperature has been useful since the development of thermometers.
Indirect measurement by Infrared detectors is being widely used today to detect FEVER as a sign of Covid in gatherings such as schools. Reactive increase of body temperature in a cool environment is a body defense mechanism that I have discussed earlier. Contrary to general practice, Fever, in my opinion, should be left untreated unless excessive, such as above 103 degrees F., or even 104 degrees.
Excessive environmental temperature, such as in a closed car, Jacuzzi, or heat wave can defeat the body’s ability to defend the normal temperature. Children, with their high body surface to mass ratio, are particularly at risk, as periodic newspaper articles testify. HEAT STROKE is the most serious of heat-related illnesses, leading to high and increasing body temperature, mental symptoms, even convulsions, and is a MEDICAL EMERGENCY.
The treatment is to call 911, and to lower the body temperature by removing insulating clothing, and immersing in cold water. There are a variety of other conditions based on excessive exertion, water or salt loss.
These include HEAT EXHAUSTION. Older Workers are particularly susceptible, and medical clinic attention may be needed for fluid and electrolyte replacement. MUSCLE CRAMPS and even damage( Rhabdomyolysis), FAINTING (this has been discussed before) and Heat Rash can result from too hot an environment. Furry Animals Pant instinctively to get their highly vascular Tongue to “air condition” their bodies. Humans should dress and exercise appropriately when the environment requires it.
