When children are in a hot environment, they can get heat-related illness. The most common problem is dehydration.
Young children have more body surface area per pound of body weight than older children and adults. They get hot more easily and lose water faster by sweating than older children and adults.
Overheating may make people very thirsty. Other signs of heat-related illness include feeling very tired, headaches, stomachaches, fever and breathing faster than usual.
Children can die when left in a vehicle. When the outside temperature is 80 degrees, the inside of a vehicle will reach nearly 110 degrees in 20 minutes. It will be hotter than 120 degrees in 60 minutes. These temperatures can kill children.
Make sure that vehicle cooling systems work well. Check every seat in the vehicle before leaving it. Be sure that no child is left behind.
