Do free divers use oxygen?
Freediving is the sport of taking deep dives with no oxygen, and one of the most crucial disciplines in freediving is static apnea (breath-holding). It is the reason behind the odd fact that we can survive without oxygen for longer when we're underwater than we can on dry land. But we can still only last for so long.

Likewise, people ask, how do free divers regulate their breathing?
Most people can hold their breath for a minute without much strain, then for another minute while fighting away the urge to breathe. Freedivers train themselves to not give into that feeling and to ignore the rising carbon dioxide in their body during a dive.

Breath-hold divers who hyperventilate before a dive increase their risk of drowning. Note that the urge to breathe is triggered by rising carbon dioxide levels in the blood and not by the reduction of oxygen. The body can actually detect low levels of oxygen but this is not normally perceptible prior to blackout.How deep can freedivers go?
