Which of the following is NOT a symptom of heat exhaustion?

Heat exhaustion is a heat-related condition that occurs when the body loses excessive amounts of water and salts, primarily through sweating. Symptoms associated with heat exhaustion typically include profuse sweating, weakness, dizziness, headache, faintness, and nausea. Skin may appear pale, cool, and clammy due to vasodilation and increased perspiration as the body attempts to cool itself.

Seizures are not a characteristic symptom of heat exhaustion but may be associated with more severe heat-related illnesses like heat stroke or could result from other underlying medical conditions. Heat stroke occurs when the body's temperature regulation fails, leading to a core temperature of 104°F (40°C) or higher, which can result in neurological dysfunction, including seizures. Thus, among the options given, seizures distinctly do not align with the typical manifestations of heat exhaustion.
