When it's hot outside, the inside of your car is a lot hotter. Especially when it's sitting in the sun.

This is why REMSA is warning against people leaving their children and pets inside their cars, even if it's just for a minute.

They're reminding you to always check your backseat before leaving your car, otherwise the consequences could be deadly to children and pets left behind.

"We understand that life can get hectic and a parent may think that they need to leave their child in a car, but we want them to understand that this can result in a true emergency," said Jennifer Walters, director of education.

According to Climate Central, Reno is the fastest warming city in the U.S.

Walters says REMSA has already responded to 36 heat-related emergencies since May.

She tells us even with the windows cracked open temperatures can rise in a car up to 20 degrees in just ten minutes. And a child is a lot more sensitive to heat than an adult.

"Children's temperatures rise faster than adults, three to five times faster, and they are less able to regulate their body temperature," she said.

She says this means children are more likely to suffer any type of heat related illnesses such as sweating, nausea, getting fussy, and eventually suffering heat stroke.

"Where the child then is unable to try and regulate their body temperature, so the sweating may cease, they might not sweat anymore, their skin will remain hot and red, they can become unconscious, have seizures, and this can even result in death," Walters explains.

If you see a child or pet stuck in a hot car with no parents in sight, immediately call 911.
