Scuba diving can be an exotic and enriching activity, but for many, it can also be a therapeutic one. The weightlessness of a water environment allows individuals with a range of injuries or disabilities to exercise, relax, have fun, and gain confidence. Children and adults with challenges including traumatic brain injuries, amputation, spinal cord injuries, cerebral palsy, and blindness can enjoy the physical and psychological benefits of scuba diving. Diveheart, a non-profit organization founded in 2001, trains thousands of volunteers and works with injured and disabled individuals across the world, in areas including the United States. Mexico, UK, Malaysia, Israel. Philippines and the Caribbean. As Darrell Young, a Vietnam veteran who is paraplegic as the result of a spinal cord injury, explains in a testimonial on the Diveheart website, 'Diving gives me a high expectancy of myself. It gives me a goal to accomplish knowing that when it comes to the finish line it doesn’t matter how I finish my dive, but the feeling of strength I gain from diving,’ he says. Diveheart relies on volunteers and donations to help provide adaptive diving and scuba therapy experiences at no cost to the participants.
