Hot cars:With summer at its hottest, here's what to know about the danger of kids left in cars

15 children have died after being left in a hot car in 2023

Fifteen children have died after being left in a hot car this year, according to NoHeatStroke.org and Kids and Car Safety.

In the past 25 years, nearly 1,000 children have died while trapped inside hot cars, according to the the U.S. National Highway Traffic Safety Administration. 

In just 10 minutes, a car can heat up by 20 degrees, the NHTSA says on its website. Even if temperatures are in the 60s outside, the inside of a car can reach 110 degrees.

“A child's body temperature rises three to five times faster than an adult's,” the NHTSA said. “A child can die when their body temperature reaches 107 degrees.”
