A professor is going to live in an underwater hotel for 100 days: Here’s what it might do to his body

As nightmares go, being trapped in a small box deep underwater is probably high on many peoples’ lists. But one US professor is doing this on purpose. 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. If he manages this, he will break a record for most time spent in a habitat beneath the surface of the ocean.
