Think of your car as a dry sauna. Even on a COOL day, with temperatures in the 60s, the car’s interior can climb to deadly temperatures in minutes. So heatstroke is NOT just a summer danger.
FACT: Keeping the windows slightly open does not significantly slow the rate of temperature rise. Nor does it significantly change the maximum temperature reached inside the vehicle.
FACT: The color of the car has little impact on how rapidly the temperature climbs.
FACT: The temperature rises quickly the first 25 minutes, and then continues rising.
A child’s core temperature climbs faster than an adult’s core temperature.
A child in a car will go into heat stress, then heat exhaustion, very quickly.
Hyperthermia/heatstroke follows and is deadly.
