Police in Paris are investigating the suffocation death of a 29-year-old gym employee during a cryotherapy session, following a nitrogen leak from a recently repaired cold chamber. A second woman, 34, is in intensive care after suffering cardiorespiratory arrest, prompting the evacuation of 150 people from the On Air gym. The Paris prosecutor’s office is conducting autopsies and toxicology analyses to determine the cause of the incidents, amid concerns about the safety of cryotherapy practices highlighted by previous warnings about the risks of nitrogen exposure.
