- A higher metabolic rate, reduced capacity for sweating, greater thermolability, and a larger body surface-to-volume ratio make infants and young children more susceptible to hyperthermia.
- Temperatures can rise rapidly within enclosed vehicles, reaching maximum temperatures within 5 minutes. In an open area with an ambient temp of 98 F (36.8 C), interior temperatures reach 124-152 F (51 to 67 C) within 15 minutes of closing the car doors.
- Texas leads the country in the numbers of pediatric heatstroke fatalities due to unattended children left in cars, followed by Florida and California.
- Most heatstroke victims (78.2%) were unknowingly left in vehicles by their caregivers.
- Most organizations interested in child safety issues recommend placing a phone, briefcase, or handbag in the back seat when traveling with a child as one way to prevent heatstroke fatalities.
