Summer Heatwaves Elevate Risk of Child Fatalities in Hot Vehicles

As early summer heatwaves sweep across the East Coast of the United States, child safety advocates are raising urgent awareness about the dangers of leaving children inside vehicles during extreme temperatures. Recent data highlights a troubling increase in hot car-related deaths, with nine children losing their lives in various states such as California, Florida, Louisiana, Maryland, New Mexico, New Jersey, and North Carolina in 2025. Notably, five of these fatalities occurred in June alone.

The threat posed by hot cars is severe and can occur regardless of the season. Climate change-induced temperature fluctuations contribute to these risks, with the inside of a vehicle rapidly becoming dangerously hot. According to Kathy Wall, director of Safe Kids Palm Beach County, the interior of a parked car can heat up by as much as 20 degrees Fahrenheit in just 20 minutes. For example, on what seems like a mild day of 80°F, the temperature inside a vehicle can exceed 100°F within ten minutes.

Historically, every U.S. state except Alaska has reported at least one hot car death since 1998. Data from the National Safety Council reveals that during 2018 and 2019, record numbers of 53 children died after being left in hot cars. Research indicates that roughly 80% of the temperature increase occurs within the first 30 minutes, with maximum temperatures potentially hitting over 150°F (65°C). Children are especially vulnerable because their bodies heat up three to five times faster than adults due to lower sweating capacity and smaller size.

Despite efforts to raise awareness, hot car fatalities can affect anyone, including caregivers and professionals. Distraction, forgetfulness, or routine changes can lead to tragic oversights. Kathy Wall emphasizes the importance of routines that serve as reminders, such as the ACT acronym: Avoid leaving children unattended, Create a personal reminder to check the backseat, and Take immediate action if a child is discovered in a vehicle.

Modern vehicles often come equipped with safety alerts, but establishing habitual checks remains crucial. Healthcare and fire safety officials encourage caregivers to develop habits like looking in the backseat before locking the car, similarly to checking mirrors. Such routines are vital to prevent heatstroke—the leading cause of non-traffic fatalities among children.

Ultimately, awareness and proactive measures are key to preventing these preventable tragedies. Creating consistent reminders, staying vigilant, and understanding the rapid rise in vehicle temperatures can save lives. Recognizing that anyone can make this mistake underscores the importance of vigilance and preventive strategies.
