‘We’re talking ice baths, in which they sit in a single-person tub of ice water that’s between 48 and 52 degrees. You think that’s cold?

Ultra-violet light therapy. Intravenous infusions. Acupuncture. Platelet-rich plasma injections. Stem-cell therapy. Cupping therapy. Electrical stimulation. And on and on.’
