Breathing is for buoyancy, it keeps you alive as an added benefit.

Holding your breath in scuba diving won't necessarily kill you, watch this video and learn why.

!!!!!!!! HOLDING YOUR BREATH WHILE ASCENDING TOWARDS THE SURFACE WILL HARM YOUR LUNGS AND CAN BE LIFETHREATHENING!!! KEEP YOUR AIRWAYS OPEN DURING AN ASCENT !!!!!!!!

Be careful and seek out a UTD instructor for more training.
