Is there any power to dive to the depth of 1000m?

The pressure under water is very high. If it is pure water, the pressure at the underwater 1000m position is about 96.75 atmospheres. The higher the density of seawater, the higher the pressure will be.

In other words, a place as big as a normal person's fingernail will have a pressure of about 100 kg. At this time, even if you want to breathe in the chest, you can't open it, not to mention the oxygen in the oxygen bottle will rush out and enter the mouth and lungs at 97 times atmospheric pressure.

Generally speaking, human dive will not exceed 100 m (which varies from person to person). If it exceeds 100 m, excessive external pressure will cause a series of problems. People have to go through a slow process to get out of the water under great pressure. If this process is too fast, you will be dizzy and die.
