Which type of heat injury is characterized by heavy sweating and fatigue?

Heat exhaustion is characterized by heavy sweating and fatigue due to prolonged exposure to high temperatures, often combined with physical exertion. This condition results from the body’s fluid and electrolyte imbalance as it loses large amounts of salt and water through sweat. As the body works harder to cool itself, symptoms such as weakness, dizziness, nausea, and muscle cramps can also occur, indicating that the individual may be on the verge of a more serious heat-related illness if not managed properly. Recognizing these signs early is crucial for effective treatment and preventing progression to conditions like heat stroke, which presents with more severe symptoms and medical complications.
