It’s expected to be one of the hottest weekends Central Ohio has seen since 2012.

And with high heat comes high risk – the most common being dehydration.MORE: Fan donations needed for people at risk of heat illness

“Many people think that the normal intake of water okay, but when we’re outside and moving around, we may be sweating and not even realize it,” says Dr. Ryan Squier of Riverside Methodist Hospital.

As adults monitor their own activity, Dr. Squier says it’s crucial they also keep track of children.

“Kids outside are definitely different. You have to understand, they’re more active when they’re outside and they’re also not aware of their need to take in water, so they go until they drop,” Squier added.

Gillian Miller was keeping her children cool and making sure they had plenty of water and sunscreen at Bicentennial Park in Columbus.

“It’s hard to keep them in line,” Miller said. “But someone’s got to do it. If the mom’s not doing it, no one else is.”

Squier said the type of beverages children consume is also crucial, as juice and soda could actually do more harm than good – he recommends sticking to water.
