A woman who worked in a cryotherapy salon and lauded the benefits of the treatment has died in her own salon’s chamber.

Chelsea Ake-Salvacion, 24, had recently given a quote to the Las Vegas Review-Journal on the benefits of cryotherapy, which puts clients in temperatures of about -240 degrees Fahrenheit, the Washington Post reports. But on Tuesday, two days before the piece was published, she entered the machine alone after hours and perished. She was found 10 hours later, but authorities say she died within minutes of entering the chamber.

Cryotherapy has gained popularity in recent years as athletes like LeBron James have talked about using it to treat pain. But the technology has not been evaluated by the FDA, and many experts question its efficacy.
