Heat Stroke Signs & Symptoms

Heat Stroke Warning Signs

Every summer, more than 2000 people go to the emergency room in Phoenix and receive IV fluids for heat-related illness like dehydration and heat stroke. Most assume the highest risk patients are the elderly and young children - and those populations do have the highest hospitalization rates.

But surprisingly, the most common heat illness patients treated in the ER are males ages 15-34, and the most common reason for heat illness was participating in outdoor sports or exercise.

Exterional Heat Stroke

This kind of heat illness is know as Exertional Heat Stroke. It's a growing concern around the globe as cities grow and turn into urban heat islands - even the 2020 Tokyo Olympics is preparing strategies for dealing with exertional heat exhaustion in the world's top athletes.

In Tokyo, researchers are stressing the importance of becoming familiar with the signs & symptoms of heat stroke, all the way from muscle cramps and mild dehydration in Stage 1 to confusion and hyperventilation in Stage 4. Educating athletes, trainers and coaches on the symptoms of each should result in earlier treatment, and fewer cases of Stage 4 heat stroke.

Attention is also being focused on pre-treating athletes on-site who show the signs and symptoms of heat stroke, instead of transporting them to the hospital and treating them on arrival. Reducing time to treatment should reduce illness severity, and may result in fewer hospitalizations.

Heat Illness in Phoenix

Athletes in Phoenix - particularly young adults and their parents - also need to get familiar with the signs and symptoms of heat stroke. Youth sports and adult pick-up leagues don't pause for the triple digits here in Phoenix, and recognizing when yourself or a teammate is showing signs of heat illness is vital.
