LOUISVILLE, Ky. (WDRB) -- It's only mid-July, and this has already been a cruel summer. But what's been uncomfortable will soon turn dangerous.

"Especially for people like me with asthma," Karen Fox of Louisville said.

Heat indices and humidity levels will soon go sky high. The worst is yet to come, and the toll it could take might be severe.

"The natural body's cooling system stops working as efficiently as it should," said a representative from the National Weather Service. "So when you get hot and sweat, you don't necessarily cool off."

The Health Department, EMS, United Way and Nation Weather Service are getting in front of it.  On Thursday, they held a news conference announcing they're opening cooling centers and that pools will be cheaper to get into because of the heat.

"They're making admission only $1 for children, $2 for adults," said Dr. Sarah Moyer, Director of Louisville Metro Department of Public Health and Wellness. "They're also reviewing the possibility of keeping the pools open longer."

Tips to beat the heat may seem obvious, but still often go unheard. Officials recommend you stay cool and hydrated, and watch out for others.

"Make sure you are checking on all friends and family, especially those who are at risk of heat exhaustion and of heat stroke," Moyer said. "This is the elderly, those that are working outside, those that have high blood pressure."

A headache, dizziness and a strong pulse are all signs of heat stroke. If you don't have anywhere to go, there are five shelters open, including Wayside Christian Mission. 

The dog days of summer can be tough, but a lot of people will take the heat over the sub-zero temps and snow of winter.
