That means that most people can dive up to a maximum of 60 feet safely. For most swimmers, a depth of 20 feet (6.09 metres) is the most they will free dive. Experienced divers can safely dive to a depth of 40 feet (12.19 metres) when exploring underwater reefs.
How deep can a human go underwater before being crushed?
Human bone crushes at about 11159 kg per square inch. This means we’d have to dive to about 35.5 km depth before bone crushes. This is three times as deep as the deepest point in our ocean.

If one descends to a depth of 100 feet (about 30 metres), the lung shrinks to about one-fourth its size at the surface. Excessive compression of the lungs in this manner causes tightness and pain in the thoracic cavity.
What happens if you swim straight up in the ocean?
Decompression sickness: Often called “the bends,” decompression sickness happens when a scuba diver ascends too quickly. Divers breathe compressed air that contains nitrogen. At higher pressure under water, the nitrogen gas goes into the body’s tissues. This can cause tissue and nerve damage.

Can water pressure kill you?
The answer is water pressure. The pressure of the water on a deep-diver’s body can crush him. Coming up from the extreme pressure of deep water to the much lower pressure at the surface is especially dangerous. Ascending too quickly can cause a fatal condition called “the bends.”
Can you dive 1000 feet?
Setting a new Guinness World Record for the deepest scuba dive, the man dove more than 1,000 feet (305 meters) below the surface of the Red Sea. Most recreational scuba divers only dive as deep as 130 feet (40 meters), according to the Professional Association of Diving Instructors.
