Intense heat can quickly become dangerous. Keep an eye on vulnerable groups including newborns, infants, children and the elderly.

“Heat is one of the leading weather-related killers in the United States, resulting in hundreds of fatalities each year,” the National Weather Service says.

To stay safe in the heat, stay hydrated and opt for water and sports drinks over sugary beverages. Take shade breaks. Know the signs of heat-related illness. Avoid strenuous outdoor activities, or move them to the cooler morning hours.

Never leave a pet or kids alone in a parked car. Temperatures in cars can rise to lethal levels within minutes, even with the windows cracked, according to KidsandCars.org.

Wearing loose, light-colored clothing can also help you stay cool.
