For a growing number of holistic-leaning celebrities, hyperbaric oxygen therapy (HBOT) has become as de rigueur as cold plunges and fitness trackers. Mayim Bialik posts selfies from her at-home chamber, which she uses to address “inflammation and autoimmune issues.” LeAnn Rimes has said that HBOT led to “a significant reduction of anxiety and depression,” and Lebron James reportedly relies on the method to reduce swelling and increase circulation.
The treatment is increasingly popping up among longevity chasing biohackers—including Bryan Johnson, who just announced on X that he had moved his office into his personal hyperbaric chamber—and at many health clubs, spas and wellness residences, including the wellness club from Whole Foods founder John Mackey.
