Rising temperatures have people looking for ways to beat the heat.
Each year, hundreds of people in the U.S. die from heat-related incidents. Heat is one of the leading weather-related killers in the U.S. according to the National Weather Service.
Some of the symptoms of heat illnesses come on gradually but can quickly get dangerous.
Spending a day at a water park is a way to cool down while taking advantage of the Central Valley heat.
While outdoors in the sun, it's important to keep safe from the potentially harmful effects of the sun.
"People think because they're in the water that they're not going to become dehydrated," says Bob Martin, general manager at Wild Water Adventure Park in Clovis.
About 70 lifeguards and three EMTs were on duty Thursday looking for signs of anyone affected by the heat.
"They see people that get light headed, dizzy, all day long going in and out of the (first aid) office," Martin says.
"They're looking for the kids that are kind of not moving as fast any more, sitting down, holding their head, anything like that," says Melissa Henry, aquatics manager at Wild Water Adventure Park.
About 3,000 children from local schools visited the water park Thursday.
Parents say while looking out for any signs of heat exhaustion in their children, they're also taking precautions so it doesn't get to that point.
"Ask them to stay hydrated and drink a lot of water," says Yahira Chacon, a parent chaperone.
"I look out for them that they're well fed before they go run around because they can get dizzy without having the right nutrition," says Adan Covarrubias, a parent who brought his three children to the water park.
If you're out in the sun, drink water every few minutes even if you're not thirsty, take plenty of rests in the shade, and look out for others who may be experiencing the symptoms of heat illnesses.
