ZAMST Presents: Heat Illness and Steps to Avoid It

 
With the increasing intensity of competitive sports these days, it is important to recognize the different types of heat illness, their signs and symptoms, and preventative measures that can be taken. In doing this as an athlete, teacher, coach, or sports medicine professional, you are one step up ahead of the very serious effects that heat illnesses can bring.
 

When an athlete is working out, his or her body’s temperature increases, and sweating is the way the body can cool itself down. But as the athlete sweats, they’re loosing essential body fluid and electrolytes. If they don’t replenish these fluids and electrolytes, dehydration can occur causing an increased risk for any of the following heat illnesses.

 

Heat Rash – a.k.a. prickly heat. A benign skin rash or irritation as a result from excess sweating without evaporation.

Heat Cramps – muscle pains or spasms during excess exertion due to dehydration and loss of electrolytes.

Heat Syncope – a.k.a. fainting. When the athlete is performing rapid, physical activities during over exposure to heat. Typically occurs due to pooling of blood in the extremities.

Heat Exhaustion – an illness that precedes a heatstroke; symptoms include heavy sweating, pale skin, rapid breathing, a fast and weak pulse with a core temperature is typically around 102°F.

Heat Stroke – a life-threatening illness in which body temperature may rise above 106°F. Symptoms include shallow breathing, dry and hot/flushed skin, a rapid & strong pulse, and dizziness sometimes leading to unconsciousness or death.
