DALLAS — It’s been a week since a Nevada spa manager was found frozen to death in a cryochamber. Turns out, Chelsea Ake-Salvacion got into the chamber alone after closing. She was inside for about 10 hours before someone found her.

With this horrible accident putting the spotlight on cryotherapy, local directors at CryoUSA are saying if used properly, it is safe.

“Number one, you never run yourself through the machine. It’s not set up to do that. We have certified operators that will come in with you,” Managing Director Eric Rauscher explained.  “During the session, it’s only three minutes long. The client’s head is completely up above the chamber. The technician is in here the entire time making eye contact, talking.”

For a lot of folks, it’s an alternative to an ice bath to get rid of aches and pains.

“In an ice bath, you’re sitting in cold water,” Rauscher said. “This is completely dry, cold air that’s flowing over the skin. It’s going half the thickness of a penny deep, so the cold goes deep enough to pick up the cold sensors.”

This chamber gets around negative 240 degrees. It was so cool, even our NewsFix crew had to give it a try.

And get this, Dallas-based CryoUSA was the first to bring this to the U.S.

“We work with a lot of runners, a lot of tennis players, soccer moms, professional athletes, we have a lot of NBA teams that swear by it. We’re working with pro football now,” Rauscher explained. “We’re not making any medical claims here, but a lot of people say that it has helped them in their recovery.”
