Heat stroke is a serious condition that can occur when the body overheats, usually as a result of prolonged exposure to high temperatures or physical exertion in hot weather. The symptoms of heat stroke can include:
- High body temperature: A core body temperature of 104 F (40 C) or higher, obtained with a rectal thermometer, is the main sign of heat stroke.
- Altered mental state or behavior: Confusion, agitation, slurred speech, irritability, delirium, seizures, and coma can all result from heat stroke.
- Alteration in sweating: In heat stroke brought on by hot weather, your skin will feel hot and dry to the touch. However, in heat stroke brought on by strenuous exercise, your skin may feel dry or slightly moist.
- Nausea and vomiting: You may feel sick to your stomach or vomit.
- Flushed skin: Your skin may turn red as your body temperature increases.
- Rapid breathing: Your breathing may become rapid and shallow.
- Racing heart rate: Your pulse may significantly increase because heat stress places a tremendous burden on your heart to help cool your body.
- Headache: Your head may throb.
If you suspect that someone may be experiencing heat stroke, seek immediate medical help. Untreated heat stroke can quickly damage the brain, heart, kidneys, and muscles, and can even be fatal.
