Extreme heat is increasingly becoming a prominent consequence of climate change, posing direct threats to human health. One of the first impacts individuals may experience is heat exhaustion, a condition resulting from excessive fluid and electrolyte loss through sweating. This occurs when the body struggles to regulate its temperature in high temperatures. Preventing heat exhaustion involves staying hydrated by drinking plenty of fluids, even before feeling thirsty, and replenishing electrolytes lost through sweat. Recognizing the early signs of heat exhaustion—such as dizziness, nausea, and headache—is crucial for prompt intervention. As climate change intensifies, understanding and combating the risks associated with extreme heat is essential for public safety and well-being. Addressing the root causes of climate change remains the most effective long-term solution.
