What are signs of heat stroke?

Heat stroke is a severe condition caused by prolonged exposure to high temperatures, often in combination with dehydration. The correct indicators of heat stroke include red, hot, usually dry skin and altered mental status.

In heat stroke, the body's ability to regulate its temperature fails, leading to a rapid increase in body temperature, often exceeding 104°F (40°C). The skin typically appears flushed and is very hot to the touch, but it may also be dry due to the body’s inability to sweat effectively at this stage. This lack of sweating, in conjunction with the hot skin, distinguishes heat stroke from other heat-related illnesses such as heat exhaustion, which typically presents with cooler, clammy skin.

Altered mental status is another critical sign of heat stroke, as the high core temperature can impair brain function, resulting in confusion, disorientation, or even unconsciousness. These symptoms highlight the urgency of recognizing heat stroke, as it can lead to serious complications, including death, if not treated promptly. Recognizing these signs is essential for initiating appropriate first aid measures and seeking medical assistance immediately.
