In brief: Heat stroke
Heat stroke can present with high temperature (104f), inability to sweat, flushing, strange behavior, high heart rate, abnormal breathing, seizures, and even coma or death.
It may or may not follow heat exhaustion characterized by nausea, vomiting, malaise, dizziness, cramping. Heat stroke is a medical emergency. Hydration and avoiding exertion in hot temperatures may prevent it.
