What are signs of heat exhaustion?

Heat exhaustion is a condition caused by excessive heat exposure, often accompanied by dehydration. The signs of heat exhaustion include cool or clammy skin along with symptoms such as headache and drowsiness. The body attempts to cool itself by increasing blood flow to the skin, which can lead to a drop in temperature despite the heat stress. This cooling process can cause the skin to feel cool and moist, and the lack of sufficient blood flow to vital organs may result in confusion or lethargic behavior.

Recognizing these early symptoms is crucial because heat exhaustion can progress to heat stroke if not addressed promptly. Understanding these signs allows individuals to take the necessary steps to cool down and rehydrate before the situation worsens. When identifying the signs of heat exhaustion, it's essential to focus on both the skin condition and accompanying cognitive or fatigue-related symptoms, as they provide a clear picture of the body's struggle with heat regulation.
