Which of these requires a 911 call for immediate medical attention?

Heat stroke is a severe medical emergency that requires immediate intervention, which is why a 911 call for medical attention is necessary. It occurs when the body overheats, typically due to prolonged exposure to high temperatures, often combined with dehydration. During heat stroke, the body's temperature regulation fails, and core body temperature can rise to dangerous levels, often exceeding 104°F (40°C). Symptoms may include confusion, altered mental state, loss of consciousness, seizures, and even organ failure if not treated swiftly.

In contrast, heat exhaustion, while still serious and needing attention, can usually be managed with prompt cooling measures and hydration. Symptoms may include heavy sweating, weakness, dizziness, and nausea, but they do not typically escalate to the critical life-threatening levels presented in heat stroke. Understanding this distinction is crucial for responding appropriately in emergencies involving heat-related illnesses.
