Why it matters:
When you’re working hard out in the sun, your body’s working overtime. If you’re not careful, that heat
can sneak up on you, causing fatigue, confusion, or worse. Heat stress isn’t just uncomfortable; it can be
dangerous.
What is Heat Stress?
Heat stress happens when your body can’t cool down fast enough. You’re losing water and salt through
sweat, and if you don’t replace them, your system starts to shut down.
Types of Heat-Related Illnesses:
• Heat Rash: Red clusters of pimples or blisters, usually on the neck, chest, or underarms.
• Heat Cramps: Muscle spasms caused by loss of salt from heavy sweating.
• Heat Exhaustion: Heavy sweating, weakness, dizziness, nausea, headache. If untreated, it can
lead to…
• Heat Stroke (Medical Emergency): Confusion, fainting, seizure, high body temp. Call 911
immediately.
Prevention Tips:
• Drink water often — even if you’re not thirsty. One cup every 15–20 minutes.
• Wear lightweight, light-colored, loose-fitting clothes.
• Take breaks in the shade or in an air-conditioned space if available.
• Avoid heavy meals during breaks; they raise your internal temperature.
• Know the symptoms of heat stress and watch out for your coworkers.
What to Do if Someone Has Heat Stress:
1. Move the person to a cooler, shaded area.
2. Loosen tight or heavy clothing.
3. Use water, fans, or damp cloths to help cool them down.
4. If symptoms are severe or not improving, call for emergency help.
Final Reminder:
If you feel dizzy, weak, or just not right, speak up. Heat-related illnesses are preventable, but only if we
take them seriously. It’s not a sign of weakness to take care of yourself, it’s part of working smart.
