Which symptom might indicate heat stroke?

The presence of flushed (red), hot, and dry skin is a classic symptom of heat stroke. This condition occurs when the body's temperature regulation fails due to excessive heat exposure, leading to an inability to sweat. The skin's appearance reflects the body’s internal temperature rising significantly, often above 104 degrees Fahrenheit.

In contrast, symptoms like pale, cool, and clammy skin more typically relate to heat exhaustion rather than heat stroke, where the body is still able to sweat, causing moisture on the skin. Normal body temperature is not indicative of heat stroke, as this condition typically involves an elevated body temperature. While vomiting can occur in cases of heat-related illnesses, it is not as definitive a symptom as the specific changes in skin temperature and condition that characterize heat stroke. Recognizing these signs is vital for taking immediate action and ensuring the safety of individuals experiencing this dangerous condition.
