Keep your kids cool on the road. Tests have shown that the temperature in a car can rise 20 degrees in just 10 minutes on a 90-degree day. There are many ways to keep you and your child cool in the car, which include putting a sunshade in the rear window and windshield while parked to shade a child car seat, and bringing a towel to sit on if you’re wearing shorts and have leather or vinyl seats.
