Heatstroke refers to the most severe form of heat-related illness that occurs when the body's system for temperature regulation has failed. It is more severe than heat exhaustion or dehydration.
Signs and symptoms begin with symptoms of heat exhaustion and include
- headache,
- dizziness and confusion,
- loss of appetite and feeling sick,
- excessive sweating and pale, clammy skin,
- cramps in the arms, legs and stomach, and
- being very thirsty.
These symptoms and signs can progress to those of heatstroke, involving seizures, confusion, and lethargy. With heatstroke, the body temperature can exceed 106 F (41 C) and sweating stops. Heatstroke is a life-threatening condition that requires emergency medical attention.
