What happens to your lungs when you scuba dive?
As you ascend,
water pressure decreases, and the air in your lungs expands
. This can make the air sacs in your lungs rupture and make it hard for you to breathe. … Divers breathe compressed air that contains nitrogen. At higher pressure under water, the nitrogen gas goes into the body’s tissues.
Why can’t divers go too deep?

that you can become confused and act as though you’ve been drinking alcohol. You might make poor decisions, such as taking out your regulator because you think you can breathe underwater.
Is scuba diving hard on your body?
