What distinguishes heat exhaustion from heat stroke?

Heat exhaustion is characterized as a milder form of heat-related illness that can be effectively managed with appropriate interventions, such as hydration and cooling strategies. Symptoms of heat exhaustion may include heavy sweating, weakness, dizziness, nausea, and headache but typically do not include the severe systemic dysfunction seen in heat stroke.

On the other hand, heat stroke represents a critical medical emergency that arises when the body's temperature regulation fails, leading to a core body temperature of 104°F (40°C) or higher. This condition can result in serious complications, including organ failure, neurological damage, and even death if not treated promptly.

Understanding the distinction between these two conditions is crucial for effective diagnosis and management. This difference in severity and the required response underscores why the correct choice emphasizes that heat exhaustion is milder and manageable while heat stroke represents a serious medical crisis.
