What is heatstroke?

Heatstroke is a severe heat-related illness that occurs when the body's temperature regulation system becomes overwhelmed, leading to a dangerous increase in body temperature. The condition is characterized by an elevated body temperature, usually above 104 degrees Fahrenheit, and can result in serious complications, including damage to internal organs and even death if not treated promptly.

One critical aspect of understanding heatstroke is its significant impact on vulnerable populations, particularly children. It is considered a leading cause of non-crash-related fatalities among children because their body temperature can rise much quicker than that of adults when subjected to high temperatures. Children often lack the ability to cool themselves through sweating as efficiently as adults, making them more susceptible to heat-related illnesses like heatstroke, especially if left in hot environments such as cars.

This understanding of heatstroke highlights its severity and the importance of preventative measures, particularly in caring for children in high-temperature situations. The other concepts, such as a mild heat-related illness or dehydration, do not capture the critical and life-threatening nature of heatstroke, distinguishing it as an emergency requiring immediate attention.
