A body temperature of 40 degrees Celsius (104 Fahrenheit) is a key sign of heatstroke, a potentially fatal medical emergency. Dr. Daniel López Rosetti recently explained the dangers of heatstroke and how to respond, emphasizing that the condition arises from a combination of intense heat exposure and physical exertion, disrupting the body’s ability to regulate fluids.
What is Heatstroke and What Are Its Risks?
Heatstroke isn’t just feeling overheated; it’s a serious breakdown in the body’s cooling system. According to Dr. López Rosetti, the condition develops when “exposure to a very hot condition in the sun, combined with physical activity, causes the body to lose its ability to regulate the amount of fluid.”
The symptoms are alarming and escalate quickly. “The person has a fever, but not a mild one—not 37.8, 38, or 39 degrees. They have a temperature of 40 degrees,” Dr. López Rosetti stated. Critically, the skin becomes hot and dry, indicating a severe lack of available fluids.
Beyond the fever, heatstroke manifests as neurological distress. Dr. López Rosetti described individuals experiencing the condition as “confused, delusional, and experiencing hallucinations.” He further noted that “seizures can occur, compromising consciousness and brain function. Breathing becomes rapid (tachypnea), the heart races (tachycardia), and blood pressure drops.”
What to Do If You Suspect Heatstroke
Children and the elderly are particularly vulnerable to heatstroke. If someone exhibits symptoms, immediate action is crucial. Dr. López Rosetti advises, “Get the person out of the heat, into the shade, and apply plenty of cool water. Remove as much clothing as possible and use a fan or running water to help lower their temperature through evaporation.” He stressed that hospitalization is essential.
Ultimately, prevention is paramount. “Avoid the heat wave, and stay hydrated,” Dr. López Rosetti emphasized. “When you feel hot, recognize that you may be approaching a heatstroke condition. In this case, prevention is clearly the key.”
