If it took you somewhere between 25 and 40, maybe 45 seconds to expel all your air, that is, you could control that exhale for about 45 seconds or 30 seconds, then you have a moderate level of carbon dioxide tolerance.

The evidence is convergent. Multiple independent sources reach the same conclusion, the underlying mechanism is well-characterized, and even the field's most cautious voices treat it as worth doing.

Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.
Would love a "what would change this verdict" RSS feed. Sign me up if it exists.
if it took you 20 seconds or less to expel all your air, that is, you couldn't extend that exhale longer than 20 seconds, in a kind of back of the envelope way, we can say that have a relatively brief or low carbon dioxide tolerance.
And if, for instance, you were able to go 50 seconds or longer for that discard until
co2 retention simultaneous oxygen and co2 retention based on the Bohr effect allows for better oxygen dissociation into tissue right in the way that you would achieve that would be to as I was talking about earlier simply take very relaxed and long exhales along with full inhale so that's oxygen and carbon dioxide tolerance
there's a gal who in november was at 25 for her exhale test 25 seconds 25 seconds and today she posted 52 seconds she more than doubled her ability to tolerate what we understand is stress
