Which of the following is a symptom of heat stress?

• A. Rash on skin
• B. Fatigue
• C. Hearing loss
• D. Increased blood pressure

Answer: (B)

Heat stress happens when the body can’t cool itself effectively in hot conditions, so energy and mental sharpness drop. Fatigue is a primary signal because overheating and dehydration reduce blood volume and impair energy, making you feel weak, tired, and less able to concentrate. This early tiredness warns you to take a break, drink water, and move to a cooler place before more serious heat illness develops. The other options aren’t typical signs of heat stress: a skin rash can come from other causes or be a different condition, hearing loss isn’t a common overheating symptom, and increased blood pressure isn’t a standard response to heat stress ( dehydration and heat exposure more often lead to dizziness or low blood pressure rather than a straightforward rise in blood pressure).
