What usually happens to the skin in classic heat stroke cases?

In classic heat stroke cases, the skin typically becomes hot, dry, and flushed due to the body's inability to dissipate heat effectively. This condition occurs when the body overheats, often as a result of prolonged exposure to high temperatures or strenuous physical activity in a hot environment. Normal thermoregulation processes, such as sweating, become impaired, leading to a lack of moisture on the skin's surface. This characteristic presentation is crucial for identifying heat stroke and differentiating it from other heat illnesses, such as heat exhaustion, where the skin may still be moist and cool as the body attempts to cool itself. The flushed appearance occurs as blood vessels dilate in an effort to release heat through the skin, further highlighting the severity of the body's hyperthermic state.
