Heatstroke is the leading cause of non-crash, vehicle-related deaths for children. According to SafeKids.org, children are at great risk for heatstroke because a child’s body heats up three to five times faster than an adult’s. When the internal body temperature reaches 104 degrees, children’s organs start to shut down. And when it reaches 107 degrees, the child can die. On average, a child dies every eight days from heatstroke in a vehicle. And a dog can die in a hot car in as little as ten minutes.
