Why Is It Dangerous To Hold Your Breath When Scuba Diving?
I just finished my scuba certification, and they told us the number one rule of scuba diving is to *never* to hold your breath. Even when you’ve lost your regulator, you’re supposed to breath out a small stream of bubbles.
Is this only because of the overcompression injuries you can get if you hold your breath and rise (which allows the air to expand/decompress, potentially rupturing a lung, etc.) or are there other reasons?
