What is Heat Stroke?
Heat stroke is a serious medical emergency. It happens when your body overheats and cannot cool down. Often, this occurs during hot weather or after intense physical activity. In the United States, heat stroke is more common in summer. If not treated quickly, it can damage your brain, heart, and other organs. Therefore, knowing the signs and acting fast can save lives.

Recognizing heat stroke symptoms early is important. Some signs appear suddenly, while others develop over time. For example, you may notice:High body temperature (above 104°F or 40°C)Hot, dry skin or heavy sweatingConfusion or trouble speakingRapid heartbeatHeadacheDizziness or faintingNausea or vomitingMuscle cramps or weaknessSeizures
Sometimes, people may stop sweating even in the heat. This is a warning sign. If you see these symptoms, act quickly.

Additionally, people living in cities may face higher risks due to the “urban heat island” effect.
Diagnosis of Heat Stroke
Doctors diagnose heat stroke by checking your symptoms and body temperature. They may ask about recent activities and weather exposure. Sometimes, they order blood tests to check for organ damage. For example, tests may look at kidney or liver function. Quick diagnosis is key to preventing serious problems.
