12 Second Breath Hold Challenge - Video

Four seconds in. Twelve seconds held. Eight seconds out.

Comment how long you can hold your breath for.

The hold is the challenge. Twelve seconds is long enough to be uncomfortable and
short enough to be sensible, and the urge to breathe you feel near the end isn't
a lack of oxygen. It's carbon dioxide building up. Your body is far more
sensitive to that than to running low on air, which is why the feeling arrives
long before there's any real problem.

Training that tolerance is the whole exercise. Your lungs don't get bigger. The
alarm gets quieter.

One thing this channel will never do: tell you to breathe rapidly before a hold.
Over-breathing first flushes out carbon dioxide, which removes the warning while
oxygen keeps dropping. That's how people black out without noticing it coming.
Every hold here starts from normal breathing for that reason.

Two rounds. Loop it if you want more.

Sit down before you start. If you feel dizzy or your vision narrows, breathe
normally and stop.

More breathing patterns and short movement breaks on the channel.
