With weather warming up quickly in the Northern Hemisphere, the U.S. Department of Health and Human Services is issuing an important reminder not to leave children or pets in hot cars, even just for a minute. According to HHS.gov, temperatures inside a car can rise 20 degrees in just 10 minutes; so if it's 90 degrees outside, the interior of a car could reach well over 100 degrees in a short period of time. Leaving a window cracked or open will not be enough to combat this drastic rise in temperature. Head over to the CDC website to learn more about how to spot heat-related illnesses in children, as well as travel tips for travelling with kids and pets in hot weather.
