An American professor, Joseph Dituri, has made history by breaking the record for the longest time living underwater without depressurization.

He achieved this incredible feat at the Florida Keys Lodge, a scuba divers' haven.

For an impressive 74 days, Joseph Dituri resided in Jules' Undersea Lodge, situated at the bottom of a 30-foot-deep lagoon.

His purpose for living under the sea was to conduct research, and in doing so, he surpassed the previous record for the longest time living underwater.

Taking to Twitter, Joseph Dituri proudly shared his achievement, stating, "Today I broke the world record for living underwater. The curiosity for discovery has led me here. My goal from day one has been to inspire generations to come, interview scientists who study life undersea, and learn how the human body functions in extreme environments."

While already holding the record of 74 days underwater, Joseph Dituri is determined to reach a new milestone of 100 days. His plan is to continue his stay at the lodge until June 9, during which he will also undertake an underwater mission known as Project Neptune 100.

This mission combines medical and ocean research, as well as educational outreach, and is organized by the Marine Resources Development Foundation, the owner of the underwater habitat.

To sustain himself during this remarkable endeavor, Joseph Dituri consumes protein-rich meals prepared using a microwave, consisting of eggs and salmon.

He engages in exercises using resistance bands, conducts daily experiments in physiology to monitor the body's response to long-term exposure to extreme pressure, and takes an hour-long nap underwater.

While Dituri acknowledges the significance of his record-breaking achievement, he emphasizes that there is still more scientific work to be done. His ultimate vision is to promote the exploration and conservation of the world's oceans, living within them and treating them with utmost care.

This incredible underwater journey has not been without its challenges, and although Joseph Dituri enjoys living beneath the ocean's surface, he admits missing the warmth of the sun.

The previous record of 73 days, two hours, and 34 minutes was set in 2014 by two Tennessee professors, Bruce Cantrell and Jessica Fain, at the same location.

Joseph Dituri has now surpassed their feat and continues to push the boundaries of human exploration and scientific research in the underwater realm.
