As temperatures soar, so do the risks for athletes training and competing in the heat. From dehydration and heat cramps to potentially life-threatening heat stroke, extreme temperatures can turn even the fittest bodies into medical emergencies.

Whether you’re a student-athlete, weekend warrior, or professional competitor, understanding the risks—and how to prevent them—is essential for performance and health. In the above video, University Orthopedics Sports Medicine Surgeon Dr. Ramin Tabaddor has advice on staying safe when the heat is on.

🌡️ Understanding Heat-Related Illnesses

Before diving into prevention, it’s important to recognize the spectrum of heat-related conditions:

• Dehydration: Reduced fluid levels impair performance and lead to cramping, dizziness, and fatigue.

• Heat Cramps: Painful muscle spasms from electrolyte loss, typically in the legs or abdomen.

• Heat Exhaustion: A serious condition marked by heavy sweating, weakness, rapid pulse, nausea, and confusion.

• Heat Stroke: A medical emergency with symptoms like high body temperature (above 104°F), altered mental state, flushed skin, and possible unconsciousness. Immediate cooling and emergency care are critical.

✅ Do: Hydrate Early and Often

Hydration isn’t just a game-day concern. It starts well before you lace up your shoes.

• Pre-hydrate 2–3 hours before activity with 16–20 oz of water.

• During exercise, aim for 7–10 oz every 10–20 minutes.

• Afterward, rehydrate with electrolyte-enhanced beverages to restore what’s lost through sweat.

Avoid alcohol, energy drinks, and caffeine, which can accelerate dehydration.

❌ Don’t Push Through Warning Signs

Athletes are trained to push limits—but in extreme heat, ignoring symptoms can be dangerous.

Stop immediately if you experience:

• Dizziness or disorientation

• Throbbing headache

• Chills or goosebumps despite the heat

• Nausea or vomiting

• Weakness or inability to continue

Rest, rehydrate, and seek medical attention if symptoms persist—it’s better to miss a workout than risk a hospitalization.

✅ Do Adjust Training Plans

Athletic output needs to adapt to the environment. When the heat index climbs:

• Train early in the morning or after sunset when temperatures are lower.

• Shorten workouts and allow longer recovery times.

• Reduce intensity—build back up slowly over days or weeks as your body acclimates.

Coaches and trainers should modify drills and enforce scheduled hydration breaks.

❌ Don’t Rely on Sweat as a Sign of Cooling

Sweating is the body’s cooling system—but it’s also the primary way we lose fluids and salt.

• Profuse sweating does not mean you’re safe—it can quickly lead to dehydration and cramps.

• Dry skin in the heat can be a warning sign of heat stroke, indicating the body has stopped sweating.

Monitor not just how much you’re sweating, but how you’re feeling overall.

✅ Do Dress for the Heat

Proper gear makes a big difference in regulating body temperature:

• Wear lightweight, moisture-wicking, and light-colored clothing.

• Avoid dark colors or cotton, which retain heat and moisture.

• Use a wide-brim hat or cooling towel during breaks.

• Sunglasses and sunscreen (SPF 30 or higher) protect from UV exposure, especially for outdoor athletes.

❌ Don’t Forget That Everyone Responds Differently

Athletes with certain risk factors may overheat faster:

• Young athletes (under 18) and older adults

• Those with a history of heat illness

• Individuals on medications like diuretics or antihistamines

• Athletes with underlying cardiac or metabolic conditions

Heat illness doesn’t discriminate—but some bodies are more vulnerable than others. Personalized monitoring is key.

In Summary

Extreme heat doesn’t mean athletes have to stop training—but it does mean they need to train smarter. By staying aware, modifying routines, and respecting the body’s limits, athletes can thrive safely even when the thermometer climbs.

Stay cool, stay hydrated, and above all—listen to your body.
