Imagine spending over three months submerged in the ocean and coming out 10 years younger. Retired naval officer Joseph Dituri did just that after living in a compact pod in the depths of the Atlantic Ocean for 93 days. His extraordinary feat wasn't just an adventure – it was a groundbreaking study into what the effects were of living underwater in a pressurised envrionment on the human body.

Dituri emerged from his 100-square-foot pod with extraordinary results. Not only did he shatter the previous world record for underwater habitation, which was 73 days, but he had also turned back the ageing clock, emerging from his pod 10 years younger. After returning to dry land, medical assessments revealed that Dituri's telomeres, the DNA caps at the ends of chromosomes that typically shrink with age, were 20 per cent longer than before his dive.

His stem cell count had also skyrocketed, and his overall health metrics had undergone a remarkable transformation.

Dituri experienced a significant improvement in sleep quality, with 60 to 66 per cent of his nights now spent in deep REM sleep.

His cholesterol levels plummeted by 72 points, and his inflammatory markers had been slashed in half. These transformations were attributed to the underwater pressure, which is known to have numerous positive effects on the .
