Joe Dettori, a former US Navy diver and expert in biomedical engineering, has been living 30 feet below the ocean’s surface since March 1, and plans to stay for 100 days. According to the site "Science Alert"If he does, he will break the record for most time spent by any human being below the surface of the ocean.
Dettori researches the effects of high pressure, when air pressure is greater than it would be at sea level, on the human body, and spends below the surface examining the impact of living in such a high-pressure environment on his health.
The suffering of the American scientist Dettori does not use an underwater submarine, and relies on a living room that a pocket of air enters at the top, but this air shrinks due to the weight of the ocean, which increases the air pressure around it. At a depth of 30 feet, the air pressure is twice what it used to be. him on the ground.
High pressure poses a real threat to humans. Nitrogen in the air is pushed through the thin walls of our lungs into our blood. This can cause a range of harmful effects. From about 30 meters below sea level and beyond, it can lead to behavior similar to toxins.
Also, Dettori would still be exposed to only half the amount of sunlight that Earth has, and that could cause problems with its circadian rhythm – "the hour" The internal organs that control many of the body’s functions, including the sleep-wake cycle – which depends on daylight, and this could mean disrupted sleep.
Another challenge for Dettori is getting enough vitamin D, and the skin must receive exposure to ultraviolet light to make this vitamin, and this usually comes from the sun, and it is possible that Dettori will not be exposed to enough vitamin D while living in its underwater environment.
