What is a simple way to prevent heat illness?

• A. Wearing PPE
• B. Hydration and breaks
• C. Running in the sun
• D. Skipping meals

Answer: (B)

Staying hydrated and taking regular breaks is the simplest, most effective way to prevent heat illness. When you work in hot conditions, your body loses fluids and electrolytes through sweat as it tries to cool you down. If you don’t replace those fluids and give your body a chance to reset, you’re more likely to experience heat cramps, heat exhaustion, or even heat stroke. Hydration helps maintain blood volume and supports ongoing sweating, while planned breaks in shade or cooler air let your core temperature drop and your system recover. Practical steps include drinking water consistently throughout the shift, using electrolyte drinks if you’re sweating a lot, and scheduling breaks—short rests every 15–20 minutes in very hot conditions and longer breaks as needed. Wear lightweight, breathable clothing, pace yourself, and watch for warning signs like dizziness or extreme fatigue. The other options either add heat load (PPE can trap heat), increase heat exposure (running in the sun), or don’t directly address heat management (skipping meals).
