When diving, I've read it's good to control your depth by breathing - for example, if I am swimming a wreck and want to lift a meter to drop into a doorway or window, I can breath in and I'll rise, drop in and continue.
I then read this is a *dangerous practice at any depth* due to the physics of air expansion and potential lung damage?
Can anyone offer advice here please?
Thank you!
