LOS ALAMITOS, Calif. – With a mission to serve disabled veterans by helping them experience the camaraderie of scuba diving and the wonders of the underwater world, a handful of volunteer staff of the Disabled Veterans SCUBA Project have started training disabled veterans to become certified scuba divers since Jan. 17, as part of a VA-approved adaptive recreational therapy program. The training is held at the Joint Forces Training Base swimming pool nearly every week, usually on Sunday evenings.
When immersed in water, paralyzed Veterans often report being able to feel areas of their bodies and a reduction of or complete lack of pain. Post Traumatic Stress Disorder Veterans state the high-focus nature of SCUBA diving helps relieve anxiety and stress. The Veterans Administration hospital is currently planning to conduct a medical study of the physical and psychological benefit of SCUBA diving on disabled veterans.
