(WEAU)--Child advocacy groups have declared Wednesday "Heat Stroke Prevention Day".
The National Highway Traffic Safety Administration says already this year, 23 children nationwide have died in hot cars. The day helps raise awareness and educate parents and caregivers about ways to prevent children from unknowingly being left alone in a hot vehicle.
KidsAndCars.org says a parked car can reach 125 degrees in minutes, even when the windows are partially open. Children are especially vulnerable to heat stroke, as their body temperatures rise three to five times faster than an adult's.
