Guide To Heat Stroke Symptoms

Heat stroke is a medical emergency that occurs when the body’s temperature regulation system fails, and the body overheats. This condition can be life-threatening if left untreated. 

When heat stroke occurs, the body temperature can rise to 106°F or higher within 10 to 15 minutes. Heat stroke can cause permanent disability or death if the person does not receive emergency treatment.

Heat stroke typically occurs during hot weather, prolonged exposure to high temperatures, and high levels of humidity. It’s important to recognize the symptoms of heat stroke to prevent serious complications.


The most common symptoms of heat stroke include high body temperature (above 103°F or 39.4°C), rapid heartbeat, and rapid breathing. Additionally, people with heat stroke may experience nausea, vomiting, headache, dizziness, confusion, seizures, and muscle cramps.

These symptoms can progress quickly, and in severe cases, can lead to unconsciousness, organ failure, and even death.

Here is a list of signs & symptoms of heat stroke to be alert for.

High Body Temperature


One of the primary symptoms of heat stroke is high body temperature. This is because the body’s thermoregulation system is unable to keep up with the external heat. When the body temperature rises above 103°F (39.4°C), it is considered a medical emergency, and immediate treatment is required. Body temperature can be measured using a thermometer, either orally or rectally, with a normal body temperature ranging from 97°F to 99°F (36.1°C to 37.2°C).

Another common symptom of heat stroke is a rapid heartbeat, also known as tachycardia. The heart beats faster to try to circulate more blood to the skin’s surface to promote heat loss through sweating. However, when the body overheats, sweating becomes ineffective, and the heart has to work harder to maintain blood pressure and circulation. A rapid heartbeat can also cause palpitations, chest pain, and shortness of breath.
