The Heat Is On!!

What is Heat Exhaustion?

Heat exhaustion occurs when your body gets too hot. The hypothalamus,the part of the brain that controls thirst and hunger, also controls the body’s core temperature. Normally, the body cools itself by sweating. But if you are exposed to high temperatures for a long time (working outdoors in the summer, for
example) and don’t replace the fluids you lose, the body systems

that regulate temperature become overwhelmed. As a result, your body
produces more heat than it can release. Heat exhaustion requires
immediate attention because it can progress to heat stroke, a
life-threatening illness.

What causes Heat Exhaustion?

Heat exhaustion occurs most often when you are exposed to high

temperatures and become dehydrated, usually from not drinking
enough fluids. It also can happen when large volumes of sweat are
replaced with fluids that don’t contain enough salt.

The warning signs of heat exhaustion include:

  • heavy sweating
  • paleness
  • muscle cramps
  • tiredness
  • weakness
  • dizziness
  • headache
  • nausea or vomiting
  • fainting

If body temperature goes above 104°F, or if coma or seizure occurs, the
patient may have heat stroke. Heat stroke can quickly lead to heart
attack and death if not treated.

How do you treat Heat Exhaustion?

Cooling measures that may be effective include:

  • cool, non-alcoholic beverages, as directed by your physician
  • rest
  • cool shower, bath, or sponge bath
  • an air-conditioned environment
  • Lightweight clothing
The skin may be cool and moist. The victim’s pulse rate will be fast and
weak, and breathing will be fast and shallow.

    Heat stroke can kill or cause damage to the brain and other internal organs. Although heat stroke mainly affects people over age 50, it also takes a toll on healthy young athletes.*’*:
