Breathing method(s) after finishing a long dive to rest.

[Johnniecy]

Greetings to all.

I was wondering what's the best method to desaturate your body of the excess cO2 that was accumulated and get enough oxygen after a long dive.

1. Start exhaling while ascending, a feet from the surface and continue to exhale until my head is out of the water, and then start breathing up ?

2. Ascend, and when and only when my head is out of the water exhale forcefully all air, then inhale, pause for a second or two, and then start breathe up ?

Thank you for your time.

Ps. Both methods breathe up takes 2x time of dive, to rest.

A big breath as soon as you surface is not a good habit, better to hook breathe. Look up 'hook breathing'. Besides your hook breaths, try not to think about it so much during recovery period. While we can exert conscious control over our breathing, your body has been engineered by mother nature to do its thing just fine on its own.

As far as exhaling before surfacing, some people exhale a little bit just before they surface for comfort, so that as soon as they break the surface they can grab a sip of air/hook breathe. If you watch video of some advanced deep divers you may see them exhale quite a bit as they ascend, but this is likely because before the dive they packed their lungs to well past normal vital capacity, and on a ascent they need to release some of the air for their own safety. You can look up packing but it is an advanced technique and not something you need to mess with until you're diving 50M+.
