Q. How deep can a human go underwater before being crushed?
How Deep Can a Human Dive Before Being Crushed? There is no fixed depth where we can say for sure that a diver will be crushed once they cross a certain depth. Most recreational divers don’t generally go beyond 130 feet, but commercial divers manage to reach depths of 2,000 feet with the help of atmospheric suits.

Q. At what depth is the ocean dark?
It is sometimes referred to as the midnight zone or the dark zone. This zone extends from 1,000 meters (3,281 feet) down to 4,000 meters (13,124 feet). Here the only visible light is that produced by the creatures themselves. The water pressure at this depth is immense, reaching 5,850 pounds per square inch.
Q. What happen if human go deep underwater?
The pressure from the water would push in on the person’s body, causing any space that’s filled with air to collapse. (The air would be compressed.) So, the lungs would collapse. The nitrogen would bind to the parts of the body that need to use oxygen, and the person would literally suffocate from the inside out.
Q. What happens to humans in deep sea?
If you’re already dead and drift down slowly from the surface, pressure in your body will likely equilibrate with sea pressure as you’re on your way down. So you end up at the bottom in largely your current size and shape – just sort of dead. And the deep-sea worms are still happy. Yay!
