Hyperthermia occurs when the body's core temperature rises excessively and can be life-threatening when the core temperature exceeds 40˚ Celsius.
Three stages characterise hyperthermia - heat cramps, heat exhaustion, and heat stroke - the latter being the most serious.
Signs and symptoms of hyperthermia are:
- Coordination issues
- Trouble concentrating
- Rapid breathing
- Rapid pulse
The treatment for a person with hypothermia is as follows:
- Move the person to a cool, shaded, well‐ventilated area.
- Sit them down.
- Loosen or remove excess clothing such as a wetsuit.
- Give the person fluids such as a cold drink.
- Use cold water to cool the person down.
- Contact professional emergency services if the patient's condition does not rapidly improve.
