The cryotherapy center in Henderson, Nevada, where a woman died last week after trying to give herself a cold-air therapy session, was shut down Tuesday by Nevada officials.
The state Division of Industrial Relations determined that the company did not have proof of a workers' compensation insurance policy, which is required by state law. "They could open as soon as proof of an adequate compensation policy is provided," said Teri Williams, a spokeswoman for the division.
The center, called Rejuvenice, offers a treatment called cryotherapy that involves spending several minutes in a tank full of air at subzero temperatures, as low as minus 240 degrees Fahrenheit. The center promises to help clients burn calories and reduce pain, but came under scrutiny when an employee was found dead in a tank on Oct. 20.
The state also found this week that the center was acting without a cosmetology license, which is required for some of the services the studio offered.
A spokeswoman for Rejuvenice, Sara Ryan, said in an email: "The company is working with the overseeing agencies to correct this issue immediately."
The woman, Chelsea Ake-Salvacion, 24, entered the tank alone after work hours. In interviews, her colleagues said it was common for employees to use the tanks, but not by themselves.
Cryotherapy is a growing industry, but it is not regulated by any one body, and medical experts dispute its benefits.
