A Florida man who spent an astonishing **100 consecutive days living underwater** says the experience has not only transformed his body and mind — but actually made him **20 years biologically younger**. According to The New York Times, retired Navy officer and biomedical science professor Joseph Dituri, known online as “Dr. Deep Sea,” made the extraordinary claim after medical tests revealed dramatic changes to his health following his record-breaking stay beneath the ocean’s surface.
Dituri, 56, lived in a pressurized habitat 30 feet below the Florida Keys for more than three months, setting the world record for the longest time spent underwater by a human. As Reuters reported, the mission was originally meant to study the effects of long-term underwater living on the human body. But when he resurfaced, doctors were stunned — his biological age markers had reversed, suggesting that the extreme environment had actually **slowed his aging process**.

Speaking to CNN, Dituri explained that doctors measured everything from telomere length — a key indicator of aging — to blood pressure, cholesterol, and sleep quality before and after his mission. “My inflammation markers dropped, my cholesterol fell, and my sleep quality improved dramatically,” he said. “It’s as if my body hit a reset button.” He also noted improved cognitive performance and energy levels, which researchers are still studying to understand how such conditions may have triggered regenerative effects.
The findings have sparked global fascination — and skepticism. As The Guardian pointed out, Dituri’s claim of “reversing aging” is not yet scientifically proven, but experts agree that his case provides a rare look into how environmental pressure, isolation, and oxygen concentration might affect human biology. The higher atmospheric pressure underwater, for example, mimics some aspects of **hyperbaric oxygen therapy**, a medical treatment known to promote tissue repair and slow cellular aging.

Social media erupted after Dituri shared photos comparing his appearance before and after the mission. His skin appeared smoother, his posture improved, and his face noticeably slimmer. As The Washington Post reported, commenters flooded his pages with disbelief and awe. “He looks like he aged backwards,” one user wrote, while another joked, “Forget Botox — I’m going scuba diving.”
However, not everyone is convinced. Some scientists cautioned that the improvements may be due to lifestyle factors rather than any miraculous underwater effect. As The Los Angeles Times noted, Dituri’s diet, exercise routine, and lack of stress while submerged could have contributed to his rejuvenation. “It’s an extraordinary experiment,” one medical researcher said, “but correlation isn’t causation.”
International outlets like BBC News reported that Dituri’s findings could reshape how scientists view human adaptation to extreme environments. NASA officials have even expressed interest in studying his results, suggesting they could help inform long-duration space missions where pressure and oxygen levels are manipulated to sustain human health.

Despite the buzz, Dituri insists his mission was never about chasing youth — but about discovery. “The point was to push human limits and see how we adapt,” he told Rolling Stone. “If aging is a disease of cellular decay, maybe we just found a way to slow it down.” He now plans to publish his full medical data and collaborate with scientists studying aging and hyperbaric medicine.
As the world debates whether he’s a scientific pioneer or simply an anomaly, one thing is undeniable — Dituri’s underwater odyssey has forced the medical community to confront a profound question: Could the key to longevity be hidden beneath the surface of the sea? “I didn’t come out younger,” he laughed in one interview, “I just came out better.”
