French divemaster Vincent Meurice developed an underwater mindfulness protocol after finding that scuba diving helped his panic attacks. This led him to develop an underwater protocol to improve mental health. The practice involves slow, deep breathing, which can have a calming effect on the body and mind. A 2020 study from Spain found patients with high levels of anxiety improved significantly compared to a control group. Meuric's work is part of emerging research that supports the restorative powers of water, particularly when we immerse ourselves in it. In 2011, he teamed up with Johns Hopkins University of Medicine and the International Center of Medicine to conduct a study on post-traumatic stress disorder, which could help veterans with physical stress disorder.
