Cryotherapy is taking the United States by storm, with many using the method to freeze body fat away.
The process is said to burn up to 800 calories in just three minutes.
For the treatment, a person stands in a liquid nitrogen filled chamber that ranges from -184 and -264 degrees Fahrenheit.
Results are said to last up to 8 hours after the treatment.
But cryotherapy has been drawing negative attention recently with the death of a 24-year-old woman in Nevada.
Chelsea Ake-Salvacion, a cryotherapy technician, reportedly got trapped while receiving the treatment alone and was found dead the next day.
A coroner ruled Tuesday that her death was as a result of suffocation.
Cryotherapy was designed 30 years ago in Japan to reduce inflammation and pain in the body.
Over the years, researchers have found additional benefits.
The therapy is not FDA approved and cost $90 a session at KryoLife in Manhattan, New York.
