Doctors say there are some simple things you can do this summer to keep from having to pay them a visit.
Most people stay out of tight spots like attics, but for Matt Slott of Conway Services, it's where he works.
"If you've ever been in a sauna before, it's pretty much exactly what it is."
Slott installs AC units for a living. He and his co-workers work in stagnate air. Some of the Mid-South attics they work in reach up to 140 degrees.
John Conway of Conway Services says, "We do a lot of training for them to be aware of the problems and be aware of the heat and to make sure they don't put themselves in harm's way."
But you don't have to work in a hot environment to put yourself at risk of getting sick.
"You deplete your hydration with day after day after day of exposure," explains Dr. Mary Ellen McIntire, Doctors Express. She also says the cumulative days of heat can cause nausea, headaches, cramping. "You feel like you can't get a deep breath."
The heat is keeping the urgent care busy. She advises everyone to take care of themselves so they won't feel the impact of the extreme heat.
"Listen to your body. Seek shade. Seek fluids, rest. You must drink enough fluids until your urine is clear."
If you aren't a fan of water, sports drinks are always good. They restore the nutrients you've lost. Something Slott knows first hand. Slott explains, "All this dead air, and, as you can see, you'll get sweaty."
