Checkups: Fighting heat illness when school sports kick off and summer is still sweltering

CINCINNATI - Students who play sports are on the field, powering through pushups, running around the track and scrimmaging on the field--usually wearing pads or protective gear.

The Centers for Disease Control and Prevention (CDC) says that heat illness during practice or competition is a leading cause of death and disability among U.S. high school athletes.

Perry Denehy, M.Ed., the lead athletic trainer for Sycamore High School, cautions young athletes and their coaches to be aware of the effect of heat on the body.

“As an athletic trainer, what I’m watching for in the athlete is those that are showing some type of fatigue," he said. "Their energy level is down, and, of course, anything like vomiting or excessive sweating.”

Denehy has worked as a trainer for over 30 years and is now employed by TriHealth.

He says the first sign of heat stress is muscle cramping, possibly in the calf or stomach. If players don’t rest and cool down at this point, they could develop heat exhaustion or heat stroke.

“Heat exhaustion is when the body systems start to fail. Fatigue, dizziness, maybe loss of consciousness will occur,” says Denehy. “Heat stroke is where the body has run out of all cooling mechanisms and the core body temperature can exceed 110 degrees.”

The signs of heat illness (CDC):

Heat Exhaustion:
heavy sweating
weakness
cold, pale, clammy skin
fast, weak pulse
nausea, vomiting or fainting

Heat Stroke
high body temperature (above 103 degrees F)
hot, red skin
dry or moist skin, without sweating
rapid pulse
mental confusion
possible unconsciousness

Denehy says heat stroke is a life-threatening situation.

“That needs to be treated as a medical emergency, calling 911, cooling the body as quickly as possible.”

Stop activity, move to a shaded area, and try to cool the body by removing some clothing and applying ice packs until emergency crews arrive.

To help prevent heat illness and ensure safety, coaches can check conditions on the playing field before practices and games, using a heat index monitor. The heat index is what the temperature feels like to the human body when relative humidity is combined with air temperature, according to the National Weather Service.The body feels warmer during humid conditions.

“When the heat index climbs too high, it’s going to be an alert to those staff to get the athletes indoors,” says Denehy.

“The Ohio High School Athletic Association recommends that any time the heat index is above 100, we have players move indoors,” says Denehy. “Below 100, we take extra precautions; recommend more frequent water breaks; and take off additional equipment if possible.”

Doctors say those water breaks are crucial. The American Academy of Pediatrics offers these tips:

  1. Start hydrating before practices and sporting events.
  2. Drink 4-8 ounces of water every 15 to 20 minutes during activity. (An athlete may become dehydrated before he or she feels thirsty.)
  3. Plain water is the best drink for most athletes.
  4. Sports drinks may be helpful only during prolonged, vigorous physical activity when there is a need for rapid replenishment of carbohydrates or electrolytes.
