Vehicular heatstroke. Hyperthermia. The devastating effects of a child being left in a hot car. It’s every parent’s unfathomable nightmare, yet it happens several times a year.

The tragedy can happen almost anywhere, and while hotter months are always the riskiest, the circumstances surrounding child vehicular heatstroke are varied.

Hot car deaths are a consistent problem

According to the safety organization Kids and Cars, an average of 37 children die each year in hot cars. These include instances where a child has been forgotten in a car, accidentally locks themselves in a car or trunk, or, in a small number of cases, when a child has been intentionally left in a car.

NoHeatStroke.org, a data site run by a meteorology and litigation expert, has been collecting data on these incidents since 1998. Since that time, the highest number of deaths per year was in 2010, with 49 deaths. 2015 had the lowest rate of incidents, with 24.

It can happen anywhere

It seems obvious that states with the highest temperatures are usually where the most deaths by vehicular heatstroke happen, but there have been instances recorded in nearly every state.

According to NoHeatStroke.org, Texas had the most such deaths from 1998 to 2015, with 100. Florida had 72 deaths, California had 44, Arizona had 30 and North Carolina had 24.

It should be noted that these figures do not adjust for population, so a larger state such as Texas or California may, statistically, have more deaths regardless of climate.

Summer always brings an onslaught of deaths

The hottest months inevitably bring the highest numbers of hypothermia incidents, so summer, late spring and early fall are the most treacherous times. Sadly, this summer has been particularly brutal. As of July 31, 29 children have died of hot car- related heatstroke, more than at this point in all previous years since 2010.

On July 18th, a 3-year-old boy in Houston died when he was left in a bus after a day care field trip. Records from the day care show the boy had erroneously been accounted for as the group reassembled after the trip. By the time the deadly oversight was realized, he had been in the bus for at least three and a half hours. When police arrived, the temperature in the bus was 113 degrees.

One of the most recent cases involves a 4-month-old Oklahoma girl who was found dead in her grandmother’s SUV after the grandmother forgot to drop the baby off at daycare. This sort of situation – where a parent or guardian forgets a child because of a lapse in temporal memory, is very common.

Younger children are more at risk

The death of a 5-year-old boy this June is an extremely unusual case, statistically speaking. A vast majority (87%) of vehicular heatstroke victims are 3 or younger. More than half (55%) are 1 or younger. According to police, the boy was found dead in a booster seat, and may have been asleep when the van arrived at the day care lot.

Laws governing the circumstances vary

While leaving a child in a hot car can certainly bring about serious legal charges, only 19 states have concrete laws on the books that make it illegal to leave a child alone in a car in the first place.

Most of these laws refer to either “leaving a child unattended” or, more broadly, “endangering a child.”

Kids and Cars reports 15 other states have proposed similar laws.

However, most organizations that combay child vehicular heatstroke argue that such laws aren’t what prevent hot car deaths, since they are almost always accidental. Kids and Cars supports several initiatives to encourage awareness and communication among drivers and caregivers.

It’s important to note many states have Good Samaritan laws that protect citizens if they intervene, reasonably, in an emergency or life-threatening situation.

Some states have outlawed leaving kids in cars alone

There are some physiological differences that make children especially susceptible to heat stroke. Here are some important facts to illustrate why vehicular heatstroke is such a problem:

Kids aren’t built for heat: Children’s body temperatures rise 3-5 times faster than adults.

Seconds count: The temperature of a car can climb 20 degrees in 20 minutes.

It doesn’t have to be hot: Heatstroke can occur in the shade, with the windows down, and even at temperatures as low as 57 degrees.
