Heatstroke is clinically defined as when a person's temperature exceeds 104 degrees F and their thermoregulatory mechanism is overwhelmed.

- Symptoms include : dizziness, disorientation, agitation, confusion, sluggishness, seizure, hot dry skin that is flushed but not sweaty, loss of consciousness, rapid heart beat, hallucinations.

When a core body temperature of 107 degrees F or greater is reached then cells are damaged and internal organs begin to shut down. This cascade of events can rapidly lead to death.

Children's thermoregulatory systems are not as efficient as an adult's and their body temperatures warm at a rate 3 to 5 times faster than an adult’s.
