An immediate obstacle to human activity under water is the fact that human lungs cannot naturally function in water environment. So, scuba diving is affected by two conditions: the pressure underwater and the air divers breathe. The pressure underwater while diving will create a problem for any air-filled spaces like the mouth, ears, para-nasal sinuses and lungs. This is because the air in those spaces is reduced in volume when under pressure.
