Hyperthermia

A dangerously overheated body, usually in response to prolonged hot, humid weather.

Overview

Hyperthermia happens when the body's heat-regulating mechanisms don't work effectively. Older age, some illnesses and some medicines increase the risk of developing hyperthermia.

Symptoms

A temperature of 104 degrees Fahrenheit (40 degrees Celsius) or higher is life-threatening. Confusion, nausea or vomiting, and rapid breathing are some symptoms.

Treatments

Take action right away to cool the person with hyperthermia while getting emergency help.

• Get the person into shade or indoors.
• Remove excess clothing.
• Cool the person with whatever means available, such as a cool tub of water or shower, cold, wet towels, or ice packs.
