How do divers hold their breath for so long?
With training, people can hold their breath much longer than most realize, allowing us to dive to remarkable depths underwater. The “mammalian dive response” causes physiological changes to the body, enabling humans to function with very low blood oxygen levels during deep dives. Air Consumption and Breathing Maintaining a slow yet deep breathing pattern results in lower air consumption which means more time underwater! By breathing deeply and drawing air down into your lungs before slowly releasing it, you are giving your body the best delivery of the oxygen it needs to function.
