HUNTSVILLE, Ala. (WHNT) - The owner of Cryotherapy North Alabama, Joan Funk, found the industry the same way most of her clients do.

"I had aches and pains, and I wasn't finding relief," Funk tells us.

She went to a treatment facility in Birmingham, then decided Huntsville needed its own.

Now there are limits to the treatment. Funk notes, "If you're pregnant, this is not for you right now. Come see us after you've had the baby. If you have some heart problems, it's not recommended."

If you want to give it a try, they'll cool the pod with nitrogen gas. Then they get you in there with a robe, gloves, and socks.

After that, they drop the temp.

"We start people out at the warmest of the cold," Funk tells us, "Which is below -100 degrees F."

They keep you moving in there, fanning you, talking to you, making sure you stay alert.

They say it's cold, but not as cold as an ice bath.

When you get out after two to three minutes, Funk says, "I feel good, and I don't mean just physically. There are some studies that show that it helps with things like depression and anxiety. You feel better."
