Which symptoms might indicate a person is experiencing heat exhaustion?

Heat exhaustion is a heat-related illness that can occur when a person becomes dehydrated and overheated, often due to prolonged exposure to high temperatures or strenuous activity in hot weather. Recognizing the symptoms is crucial for timely intervention and treatment.

The symptoms associated with heat exhaustion include profuse sweating and dizziness. Profuse sweating occurs as the body attempts to cool itself down through evaporation, which is an essential mechanism for thermoregulation. Dizziness can arise from the loss of fluids and electrolytes, leading to low blood pressure and inadequate blood flow to the brain. When both symptoms are present, they strongly indicate that the individual is experiencing heat exhaustion and needs to be cooled down and rehydrated as soon as possible.

Other potential symptoms of heat exhaustion may include weakness, nausea, headache, and elevated body temperature, which further emphasize the need for immediate care in such situations.
