Which symptom is commonly associated with heat exhaustion?

Nausea is a common symptom associated with heat exhaustion because it typically occurs as the body struggles to cope with excessive heat. When the body overheats, it can lead to dehydration and electrolyte imbalances. These changes often trigger nausea as a protective response, signaling that the body is under stress.

In the context of heat exhaustion, other symptoms can include excessive sweating, weakness, dizziness, and muscle cramps. While severe headache and rapid heartbeat can occur as well, they are not as specifically linked to heat exhaustion as nausea. Persistent hiccups are generally not a symptom associated with this condition. Recognizing nausea as a key indicator allows individuals to take proactive steps to cool down and hydrate, which are critical in preventing the progression to more severe heat-related illnesses.
