Heat Safety: Preventing Heat Illness During Outdoor Activities

Heat-related illnesses are among the most common weather emergencies affecting athletes, workers, and outdoor event participants. High temperatures combined with humidity can overwhelm the body's ability to cool itself, increasing the risk of dehydration, heat exhaustion, and life-threatening heat stroke.

Why Heat Is Dangerous

The body cools itself primarily through sweating. When humidity is high, sweat evaporates more slowly, making it harder for the body to release heat.

Several environmental factors influence heat stress, including:

• Air temperature
• Relative humidity
• Solar radiation
• Wind speed
• Surface temperatures
• Activity level
• Protective equipment

Common Heat Illnesses

Heat Cramps

Early warning signs include painful muscle cramps caused by dehydration and electrolyte loss.

Heat Exhaustion

Symptoms include:

• Heavy sweating
• Weakness
• Dizziness
• Nausea
• Headache
• Rapid pulse

Heat Stroke

Heat stroke is a medical emergency. Symptoms include:

• Confusion
• Collapse
• Loss of consciousness
• Body temperature above 104°F
• Hot skin
• Seizures

Call 911 immediately.

Prevention

Reduce risk by:

• Drinking water frequently
• Scheduling rest breaks
• Wearing light-colored clothing
• Providing shade
• Gradually acclimating athletes to heat
• Monitoring environmental conditions

Why WBGT Matters

Unlike the Heat Index, Wet Bulb Globe Temperature (WBGT) considers:

• Air temperature
• Humidity
• Wind
• Sun angle
• Solar radiation

This makes WBGT the preferred measurement for athletic safety.

How CWP Weather Alerts Helps

The platform provides:

• Heat Index
• WBGT
• Hourly trends
• Weather alerts
• Real-time monitoring

These tools help coaches and organizers make informed decisions before conditions become dangerous.
