Name two signs of heat stress in workers.

• A. Coughing and sneezing.
• B. Cold chills and shivering.
• C. Dizziness and confusion; excessive sweating and headache.
• D. Hearing loss and improved concentration.

Answer: (C)

Recognizing heat-related illness comes from noticing signs that reflect how heat affects both the brain and the body. Dizziness and confusion are strong indicators because they show the brain is being stressed by heat, which can impair clarity and balance. Excessive sweating combined with a headache is another common sign, pointing to dehydration and the body's effort to cool down. The combination of these symptoms closely matches how heat stress presents in workers, making this option the best choice. The other options describe symptoms that don’t align with heat stress—coughing and sneezing point to respiratory issues, cold chills and shivering to cold exposure, and hearing loss or improved concentration aren’t typical signs of overheating. If you observe these signs, take steps to cool the worker and hydrate, and seek medical help if confusion, fainting, or other severe symptoms appear.
