What happens to your body when diving?
Breathing air under increased pressure, as you do when scuba diving, also affects your heart and circulatory system. Increased levels of oxygen cause vasoconstriction, increase your blood pressure and reduce your heart rate and heart output.
What happens if you dive for too long?
This is possible if you hold your breath for too long when you’re under water or if you surface from the water too quickly. These actions can cause the air sacs in your lungs, called alveoli, to rupture. When the alveoli rupture, air may move to your arteries, resulting in an air embolism.

Why can’t humans go deep underwater?
Since the water down at those depths is still liquid and not solid, there is not enough depth in our ocean to solidify water simply with pressure. Water remains a liquid at even 1101 bar or pressure. The human body would therefore not solidify under that pressure.
Does scuba diving shorten your life?
