Which symptom is commonly associated with heat cramps?

Heat cramps are characterized by involuntary muscle contractions that typically occur in the larger muscle groups, such as the calves, thighs, and shoulders. These cramps happen as a result of prolonged exercise in high temperatures, leading to an imbalance of electrolytes, especially sodium and potassium. The cramping is a direct response to intense physical exertion combined with heat and can be a warning sign of heat-related illnesses.

While elevated body temperature, altered mental status, and nausea might be associated with heat-related conditions, they are not specific symptoms of heat cramps. Elevated body temperature is more related to heat exhaustion or heat stroke. Altered mental status can occur with severe heat illnesses, while nausea and vomiting are also more commonly seen in conditions like heat exhaustion. Thus, the symptom most specifically linked to heat cramps is the cramping of the larger muscles.
