Galveston County Daily News (Internet / Print) 07/14/06 Weekly Column by Dr. Sally Robinson and Dr. Keith Bly: Every year there are new reports of children dying after being left in cars for hours in hot weather. In fact, every year an average of 25 children die after being left or getting trapped in hot vehicles. The inside of a car can heat up very quickly — even when the temperature outdoors is mild. On an especially hot day, the interior of a car can heat up to 122 F in less than 20 minutes, and within 40 minutes, it can get so hot that a child left inside a car for that length of time can die. Even leaving the window of the car open slightly does not do enough to keep the temperature safe for a child. Young children, especially infants, are more sensitive to heat than adults because their bodies do not regulate temperature as well as adults’ bodies. A child left in a hot car can suffer from heat stress, dehydration and shock.
