As the heat index climbs into the triple digits, the state health department is urging Oklahomans to stay in air conditioned locations.
Laswanique Gray provides tips to anyone who needs to go outside.
"Wear a hat to cover your head and loose-fitting, light-colored clothing, sunscreen is a must and sunglasses if you can. Drink plenty of water. Take plenty of breaks."
To avoid hyperthermia or overheating, Laswanique recommends drinking two to four glasses of water an hour.
