Dozens of people on social networks have challenged themselves to take an ice bath (between 0°C and 10°C) every day. These men and women who film themselves on their terrace or in their garden extol the merits of these daily immersions in a trash can.
An American woman followed by more than a million people has continued to take ice baths since announcing her pregnancy. Icespiration, a French brand that sells portable ice baths, even tells its subscribers that it helps you lose weight.
