TULSA, Oklahoma - Friday was the hottest day in Oklahoma in six years and the heat can be tough for anyone who spends a lot of time outdoors.

In every part of the city, you can find people outside in the heat, doing what they can to stay cool.

Caleb Allen with EMSA says early symptoms you're getting sick from the heat include muscle cramps, nausea, vomiting, and dizziness. Those who aren't exposed to heat as much can be more vulnerable if they suddenly spend too much time outside.

"What we're seeing is more younger adults that are being more active in this heat who haven't yet adjusted or who haven't taken into account how bad the heat is," said Allen

Like many others, Andrea Dillard and her kids are taking any chance they can to escape the heat.

Friday, a splash pad was their escape.

"You just have to be kind of strategic about it. So, you have to find a place that has water or shade and limit the time that you're out," said Dillard

And triple digit days like Friday have a lot of people finding alternatives plans to keep them out of the heat.

"We have plans to do indoor activities science museums stuff like that so you try to get in the air conditioning at some point during the day," said Dillard.

If you're out in the summer heat, EMSA says to make sure you bring lots of water and sunscreen. EMSA says despite all that time you spend in the water you can still get dehydrated or have heat exhaustion.
