Answer 1

Yes, yes it can cause pressure damage like empty soda cans.

So air is less dense that water and in order to function, you as a person have air in your lungs and oxygen dissolved in your blood stream. So you are less dense than water which is why you can float on water.

If you descend too deep or too fast the pressure can make your lungs cave in or the dissolved oxygen in your blood could form bubbles which can kill you.
It’s why divers have to descend and ascend slowly so their bodies can acclimatise slowly.
