Which of the following is a symptom of heat cramps?

Heat cramps are typically associated with an individual experiencing muscle spasms that occur during or after intense physical activity in a hot environment, often due to an imbalance of electrolytes and dehydration. Profuse sweating is a key symptom of heat cramps as the body attempts to cool itself down, leading to the loss of both water and essential salts, such as sodium and potassium. This excessive sweating can result in muscle cramping due to the loss of these vital electrolytes.

The presence of profuse sweating indicates that the body is under stress from high temperatures, which is closely related to the onset of heat cramps. In contrast, rapid heart rate, dilated pupils, and fever over 101°F are more indicative of other heat-related illnesses or medical conditions rather than specifically pointing to heat cramps alone. Understanding these symptoms is crucial for recognizing and addressing heat-related issues promptly.
