Explore sunstroke, a severe heat-related illness. Understand its signs, dangers, and preventive measures in this concise overview

A core body temperature of 104°F (40°C) or higher is a hallmark sign of heat stroke

Confusion, agitation, slurred speech, irritability, delirium, or even coma can occur as the brain is affected by the heat. Heat stroke can impair cognitive function

The skin may become red, hot, and dry, as the body's ability to sweat and cool down becomes compromised. However, in some cases, the skin may still be moist

The body may attempt to cool down by increasing respiration rate. Rapid, shallow breathing is common in individuals experiencing heat stroke

Heat stroke can cause the heart to beat rapidly as it tries to pump blood to the skin's surface to facilitate cooling. This can lead to palpitations and an increased pulse rate

Heat stroke can upset the gastrointestinal system, leading to nausea, vomiting, and sometimes diarrhea. Dehydration and electrolyte imbalances exacerbate these symptoms
