A man who spent 100 days living underwater off the coast of the Florida Keys got some surprising results after undergoing tests on dry land to find out what the experience had done to his body.

Doctor Joseph Dituri, who has earned the nickname Dr Deep, for obvious reasons, spent more than three months 30 feet under water at a Key Largo lagoon inside a special pod. 

His impressive feat, which took place in 2023, earned him a place in the Guinness World Records for the longest time spent living in an underwater fixed habitat. 

Once back on land, Dituri was tested to see what sort of impact his time underwater had on his body and it was striking.

The incredible experiment set a new world record

Dituri smashed the old world record of  73 days, two hours and 34 minutes by more than two weeks, but he has since lost the title to someone who managed 120 days. 

However, for Dr Deep it wasn’t about gaining records and titles. 

“It was never about the record,” Dituri told CBS News

“It was about extending human tolerance for the underwater world and for an isolated, confined, extreme environment.”

Unlike a submarine, the pod Dituri stayed in was designed to have the same pressure found outside the pod. 

He wanted to know how living in a pressurized environment for so long would affect the human body, and said the results could help both ocean researchers and astronauts planning manned-missions to Mars, a little like the experiment NASA recently launched.

Inside the pod Dituri had everything he needed to keep going, including a full-sized bed, bathroom, food, water, and books – he even brought along resistance bands so he could work out. 

But that’s not to say that being back on land didn’t have its challenges. 

Speaking shortly after he set the record, Dituri said he experienced ‘sensory stimulation overload’ when trying to drive home.

He was tested after 100 days living underwater, with surprising results

However, it’s the impact on his body that makes Dituri’s experiment so interesting. 

Living underwater in the pressurized environment resulted in a ‘life glitch’, which Dituri said actually de-aged him, with his cells appearing younger than when he had gone in. 

Speaking to NBC News he revealed he’d taken a raft of tests after exiting the underwater pod and found that he had decreased cholesterol, reduced inflammation in his body, and now had a better ability to focus on tasks. 

He also said he was sleeping better, and thanks to his workout he managed to maintain his body mass. 

It’s just a shame it’s not the most practical way to get fit and healthy…
