Scuba (self-contained underwater breathing apparatus) diving is true underwater freedom. Stay underwater far longer than snorkelers and free-divers and explore fish, coral and the wonders of the deep.
For a technical explanation of what actually goes on with breathing underwater, a quick survey of the principles of pressure is needed. Unlike people on land who experience normal atmostpheric pressure, scuba divers must also withstand increasing (with depth) water pressure too.
This means the pressure of inhaled breath must equal the surrounding (ambient) pressure to sufficiently inflate the diver’s lungs. It is the job of the demand valve regulators that achieve this task, allowing natural breathing for the diver at any depth.
Divers cannot breathe in through their noses because of the design of the divers mask (with the exception of full face masks) but this is something divers become quickly accustomed to.
Divers can take advantage of scuba dive training and certification agencies in order to progress in the world of diving. If you’ve dreamed of becoming a dive instructor and traveling the world, there are many diving organizations out there for you.
