Lower depths require the ability of the body or the submarine to withstand higher pressures. When doing SCUBA diving, the higher pressure on the blood in the body forces the absorption of more nitrogen into the blood, assuming that an oxygen/nitrogen mixture is being breathed. 

Now as the diver starts ascending towards lower depths, these dissolved gases start coming out in the form of bubbles and can create a fatal condition called as "Bends"
