A professor is going to live in an underwater hotel for 100 days – here's what it might do to his body

Joe Dituri, a former US navy diver and expert in biomedical engineering has been living in a 55 square meter space 30 feet below the surface of the Florida Keys since March 1, and plans to stay for 100 days..

Dituri conducts research into the effects of hyperbaric pressure when air pressure is greater than it would be at sea level on the human body..

But Dituris underwater habitat wont have any solid hatches or air locks between the ocean and the dry living space, as a submarine does..

A pocket of air will still exist at the top of Dituri's living space, with a pool of water in the floor of one room that comes from the ocean outside.. This means that the air inside his habitat is squeezed by the ocean's weight, increasing the air pressure around him..

While Dituri's underwater habitat will be different from a submarine, the amount of time he's spending there is not altogether different from what many submarine crews endure..
