According to Safe Kids Worldwide, a child dies from heatstroke in a vehicle about every 10 days. In more than half of these deaths, the caregiver forgot the child was in the car. Pediatric critical care physician Jason Peck, M.D., pediatric intensivist at Palmetto Health Children’s Hospital, has seen the tragic results of children being inadvertently left in hot cars.
With high temperatures across much of the south, Peck reminds people that children have died from heatstroke in a vehicle with outside temperatures as low as 57 degrees Fahrenheit (F). "A child’s body heats up three to five times faster than an adult’s body. The temperature inside a vehicle can reach life-threatening temperatures rapidly," said Peck.
The number of heat stroke deaths of children left unattended in vehicles in the United States has been steadily trending upward. Between 2003 and 2012, there were 384 heat-related deaths due to children being left unattended in cars. Almost one-third of those deaths occurred at temperatures of less than 90 degrees. In addition to these deaths, it is estimated that hundreds of children annually will experience heat-related illness due to being left unattended in cars. Results of heat illness can be severe and permanent.
Temperatures less than 70 degrees have been associated with internal temperature in cars reaching over 105 degrees. Leaving the window open does not affect how fast the temperature rises. On hot days, the maximum temperature that a car will reach occurs within 15 minutes, and can reach temperature of 120-150 degrees.
In just 10 minutes, a car’s interior temperature can rise by 19 degrees. Between one and two hours, it can rise 45–50 degrees. "Leaving the windows cracked does not make a significant difference, so it is not an acceptable compromise," said Peck.
Hyperthermia (heatstroke) is the leading cause of non-crash vehicle deaths for children under the age of fourteen. Heatstroke can occur when a person’s temperature exceeds 104 degrees F and their body’s temperature regulating system is overwhelmed.
Symptoms of hyperthermia include:
"Everyone thinks it couldn’t happen to them, but a parent who is distracted might inadvertently leave a child in the car," Peck said. "A caregiver who is not the person usually responsible for the child can forget that there is a child in the car, especially if the child is quiet or sleeping."
A core body temperature of 107 degrees F can be lethal, as cells may be damaged and internal organs shut down. Cases of death from hyperthermia in vehicles have happened to children from newborn to age 14. More than half of these deaths have occurred in children under the age of two.
Tips from Safe Kids USA and the National Highway Traffic Safety Administration include:
Take steps to remember not to leave a child in a vehicle, such as:
Call 911 immediately if you see a child left alone in a hot vehicle. When children are in distress due to heat, get them out of the vehicle as quickly as possible.
