Heat cramps are defined by which symptom?

• A. Heat Exhaustion
• B. Heat Cramps
• C. Heat Stroke
• D. Mild Hypothermia

Answer: (B)

Heat cramps occur when muscles contract painfully during or after heavy sweating in a hot environment, due to dehydration and loss of electrolytes like sodium and potassium. This cramps-focused symptom is the defining feature of heat cramps, setting it apart from other heat-related illnesses that present with broader systemic signs. Heat exhaustion, for example, includes dizziness, fatigue, nausea, and rapid heartbeat, while heat stroke involves confusion or altered mental status with a very high body temperature. Mild hypothermia, on the other hand, is about low body temperature from cold exposure. So the best answer is the one that describes painful muscle cramps as the central symptom, reflecting the electrolyte-depletion mechanism behind heat cramps. If cramps persist or are accompanied by fainting, dizziness, or confusion, seek medical attention.
