These are an arcane subset of the "sport", called "free divers". THink of the pearl divers of Japan etc for antecedents. With proper training, one can hold one's breath underwater foramazing lengths of time. I think the record is around 20 minutes...

One reason is the diving reflex, an evolutionary adaptation that enables seals and dolphins to dive deep and stay underwater for extended periods by slowing and/or shutting down some physiological functions. As scientists have discovered, even though humans evolved on land, we've retained a trace of that reflex, too. Freedivers have learned to push self-induced apnea -- the scientific term for going without breathing -- to new extremes through sophisticated mind-body control techniques similar to those employed by meditating yogis and martial artists. |
As for the filming, they did it is several sessions over several days, so no, not all in one take. |
