Every summer, heartbreaking and preventable deaths occur when children are unintentionally left alone in hot cars.

All types of parents.”Earlier this year a Colorado mother – Heather Jensen – was sentenced to 10 years in prison for the death of her sons. Jensen was found guilty of child abuse after she left her sons in her car to have sex with her boyfriend.According to KidsAndCars.org, nearly 400 children in the United States have died in hot cars in the last decade.The summer heat and humidity can also spell trouble for children who spend time outdoors, since a child’s body heats up much faster than an adult’s.Dr. Eric Kirkendall at Cincinnati Children’s Hospital Medical Center says that makes children more susceptible to heat exhaustion, heat cramps and heatstroke.“And that includes hot, flushed skin typically associated with high fevers, over 104 degrees,” he explains. “And that’s when kids will also start to have altered mental states.“So, they’ll start getting really confused, and in some of the worst cases can have seizures.”Kirkendall says to protect against heat-related illnesses, parents need to make sure their children stay hydrated and that their exposure to the sun is limited.
