- Confusion, altered mental status, slurred speech.
- Loss of consciousness (coma)
- Hot, dry skin or profuse sweating.
- Seizures.

- Fatal if treatment delayed.
How long does it take to get heat stroke?
Heat stroke can set in quickly over the course of 10-15 minutes, or slowly, developing over several hours or days. It’s important to monitor someone for signs of heat exhaustion or heat stroke for a few days after extreme heat exposure.
