Extreme heat can be dangerous for kids, experts warn

With more record-breaking temperatures in the forecast for parts of the country, public health experts are cautioning that children are more susceptible to heat illness than adults are — even more so when they're on the athletic field, living without air conditioning, or waiting in a parked car.

Cases of heat-related illness are rising with average air temperatures, and experts say almost half of those getting sick are children. The reason is twofold: Children's bodies have more trouble regulating temperature than those of adults, and they rely on adults to help protect them from overheating.

Parents, coaches, and other caretakers, who can experience the same heat very differently than kids do, may struggle to identify a dangerous situation or catch the early symptoms of heat-related illness in children.
