Which statement is true about heat stress prevention methods?

• A. Hydration is unnecessary if you take breaks
• B. Wearing heavy clothing reduces heat stress
• C. Hydration and breaks are a primary method to prevent heat stress
• D. No measures are needed in cool weather

Answer: (C)

Staying hydrated and taking regular breaks are central ways to keep heat stress from developing. When you’re active in heat, your body relies on sweating to cool down and maintain blood volume. Adequate fluids help replace what's lost in sweat, support heart and kidney function, and keep your core temperature under control. Breaks give the body time to shed heat in a cooler environment, reduce strain on the heart, and provide a chance to rehydrate and recover before resuming work. While breaks alone can help, without hydration the risk of dehydration and heat illness remains, and simply wearing heavy clothing or working without breaks does not prevent heat buildup. In cool weather, the risk may be lower, but heat stress prevention still matters if you’re exerting yourself or in sunny or humid conditions.
