- Very rapid or dramatically slowed heartbeat
- Rapid rise in body temperature that reaches 104 to 106 degrees Fahrenheit
- Either drenching sweats accompanied by cold, clammy skin (which may indicate heat exhaustion); or a marked decrease in sweating accompanied by hot, flushed, dry skin (which may indicate heat stroke)
