Underwater Experiment: 100 Days of Life at Depth (4 photos + 1 video)
It's nice to be a scientist, sitting in your office and wondering what would happen to a person if they decided to live in the depths of the ocean, about 9 meters below the surface, for three and a half months. And then you go and conduct this fascinating experiment. All in the name of science, of course. 
University of South Florida scientist Joseph Dituri spent 100 days at the Jules' Undersea Lodge, located at a depth of 9 meters in Key Largo Lagoon, Florida.
The aim of the study was to investigate the effects of prolonged underwater exposure on human health, which has implications for future space missions and marine exploration. 
The habitation module was a sealed structure approximately nine square meters in area. The airlock room, known as the "moon well," maintained pressure to prevent water penetration. Divers used this well to deliver food in containers. Two cylindrical compartments extended from the room: one served as a bedroom with a bunk and monitors, the other as a kitchen/living room with minimal appliances. Conditions included oxygen-enhanced ventilation and internet access for online activities. 
Dituri studied changes in the body under hyperbaric pressure. The experiment showed that staying underwater at elevated pressure depths slowed the aging process at a biological level; his cells functioned like those of a younger person. 
The participant's immunity increased by 65%, and his gut microbiome adapted to the conditions. However, side effects were observed: a half-centimeter compression of the body, joint pain, and accelerated hair growth. The researcher also collected data on 114 marine species for ecological research.

The experiment was successful. Dituri, who has experience in the Navy and over 28 years of diving, noted the value of the data obtained for medicine and oceanography. The results are of interest for hyperbaric therapy and preparation for long-term spaceflight.
In short, if you're fed up with everything on the surface, you can go underwater, but only for a short time.
