Number of child hot-car deaths in 2016 reaches 23

Over the weekend, four children died while being left in hot cars, raising the total number of children who died from vehicular heatstroke in 2016 to 23, according to KidsAndCars.org.

On July 22, a 4-year-old in Williamsport, Pa., and a 3-year-old in Navarre, Fla. died. On July 23, a 2-year-old boy in Rocky Comfort, Mo., and on July 24, a 3-year-old in Dallas, Tex., also died.

According to KidsAndCars.org, since 2010, 241 children have died from vehicular heatstroke. Since 1998, an average of 37 children die each year.

On a sunny day, the temperature inside a car can rise 40 degrees within an hour, according to a Stanford University study. When it's 90 degrees outside, the temperature inside a car can soar to over 160 degrees, according to AccuWeather.

KidsAndCars.org recommends setting up reminders to prevent leaving children in hot cars. One idea is to buckle a stuffed animal in a child's car seat when parked, placing it in the front passenger seat while driving.
