In this week’s Keeping Kids Healthy column by UTMB Drs. Sally Robinson and Keith Bly: Every year, there are new reports of children dying after being left in hot cars. 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 degrees in less than 20 minutes; within 40 minutes, it can get so hot that a child left inside a car for that length of time can die. Many parents think that leaving a window of the car open slightly will keep the temperature lower, but fail to realize it will still remain too hot in the car for the child.
