Which heat-related condition presents with the symptom of no perspiration?

• A. Heat cramps
• B. Heat stroke
• C. Heat exhaustion
• D. Hypothermia

Answer: (B)

Lack of sweating points to heat stroke, because when the body's cooling system fails, the person can stop sweating even in hot conditions. This absence of perspiration signals a critical disruption in thermoregulation, making heat stroke a medical emergency. Heat cramps and heat exhaustion involve sweating and dehydration symptoms, so sweating is still present there. Hypothermia is a cold-related condition and isn’t defined by heat-induced sweating patterns. High body temperature with altered mental status and dry, hot skin (as sweating ceases) is a hallmark of heat stroke.
