Heat stroke is the result of dehydration thermoregulation failure, i.e., the body's inability to sweat. Which statement is true?

• A. It is always a minor condition.
• B. It occurs as a result of thermoregulation failure and requires medical attention.
• C. It is the same as heat cramps.
• D. It occurs only in cold climates.

Answer: (B)

Heat stroke happens when the body's cooling system fails, typically because dehydration prevents sweating. Without sweating to lose heat, core body temperature rises rapidly, which can impair brain function and damage organs. Because this is a medical emergency that demands prompt cooling and professional care, it requires medical attention. This is different from heat cramps, which are painful muscle spasms, and from milder heat-related conditions like heat exhaustion. It also isn’t limited to cold climates; heat stroke occurs in hot environments when the body's temperature regulation breaks down. So the true statement is that heat stroke results from thermoregulation failure and requires medical attention. If you suspect heat stroke, seek emergency help, move the person to a cooler place, remove excess clothing, and begin cooling.
