Whether you’re managing a team that works outdoors or simply spending more time outside during the summer months, heat-related illnesses are a serious risk that shouldn’t be overlooked. High temperatures and prolonged sun exposure can quickly become dangerous without the right precautions.
Understanding the warning signs of heat exhaustion and heat stroke, and knowing how to respond, can help keep you, your family, and your employees safe all summer long.
Recognizing Heat-Related Illness
Heat-related illness can range from mild symptoms to life-threatening emergencies. Watch for signs such as:
- Heavy sweating
- Headache, dizziness, or fainting
- Muscle cramps or weakness
- Nausea or vomiting
- Confusion or irritability
- Rapid breathing or pulse
- Hot, dry skin
- Loss of coordination or unconsciousness
Symptoms like heavy sweating, fatigue, and dizziness may point to heat exhaustion, while confusion, hot dry skin, or unconsciousness can signal heat stroke, which requires immediate medical attention.
Tips to Stay Safe in the Heat
Heat related illnesses kill many people every year and hospitalize thousands more. To keep yourself, your family, and your employees safe in the sun, remember these tips:
Plan ahead
Check the forecast and heat index before outdoor work or activities. If temperatures are especially high, adjust schedules when possible and make sure everyone knows the warning signs of heat-related illness.
Stay rested and hydrated
Drink water regularly and take frequent breaks in shaded or air-conditioned areas. Waiting until you feel overheated can be too late.
Dress for hot weather
Wear lightweight, loose-fitting clothing in lighter colors. Hats with a brim can also help protect against direct sun exposure.
Give Your Body Time to Adjust
It can take several days for the body to adapt to working or exercising in high heat. Ease into strenuous activity gradually and allow for additional breaks during hotter conditions.
What to Do in an Emergency
If someone appears to be suffering from heat stroke:
- Call 911 immediately
- Move them to a cool or shaded area
- Remove excess clothing
- Apply cool, wet towels or ice packs to the head, neck, armpits, and groin
- Use fans or ventilation to help cool the body while waiting for emergency responders
Heat-related illnesses can happen quickly, especially during outdoor work or physical activity. A little preparation, hydration, and awareness can go a long way toward helping everyone stay safer in the summer heat.
