Heat exhaustion is a condition that arises when the body overheats and can’t cool itself efficiently. It’s common during outdoor work, sports, or even long commutes on hot days. While mild, it can quickly worsen into heat stroke if ignored, making early recognition essential.
Symptoms range from fatigue and dizziness to nausea, headache, and excessive sweating. Many people mistake these signs for dehydration or a simple heat‑related illness, delaying proper care. Identifying the exact pattern helps trigger timely intervention and reduces risk.
