Heat Stress Is a Leading Cause of Summer Illness


Heat stress is a signal that says the body is having difficulty maintaining its narrow temperature range.  The heart pumps faster, blood is diverted from internal organs to the skin, breathing rate increases, and sweating increases, all in an attempt to transfer more heat to the outside air and cool the skin by the evaporation of sweat.  If the body cannot keep up, then the person suffers effects ranging from heat cramps to heat exhaustion, and finally to heat stroke.  The next stage is most often fainting and even death if the person is not cooled down.  The major heat stress injuries and illnesses range from heat rash, heat cramps, heat exhaustion, and then heat stroke.

The most serious heat-related problem is heat stroke, which is life threatening.  Heat stroke occurs when the core temperature rises so high that the body’s normal cooling mechanism ceases to function.  In effect, the brain gives up and stops doing the things it normally does to maintain body temperature at a constant level.
Heat exhaustion occurs most often when you are exposed to high temperatures and become dehydrated, usually from not drinking enough fluids. It can also happen when you replace large volumes of sweat with fluids that do not contain enough salt.

Are There Supplements That Can Help?

Supplements are not a cure for heat stroke, but there are many medical professionals who have identified supplements that can help.  Always drink plenty of water.
