Red face Why does packing lungs cause dizziness?
permalink
Is it recommended that we pack our lungs with air before diving?By packing I am referring to sucking in extra gulps of air after taking a full deep breath for a static apnea breath hold.

I tried doing this this and noticed that I can get momentarily really dizzy for a few seconds around the 5th pack. After a few seconds the dizziness passes away and I'm ok.

Q1. Is this similar to hyperventilating?

Q2. Why does packing the lungs with extra air cause dizziness?

Mahalo,
Peter
