[00:00:00]A swimmer takes a deep breath before diving underwater in a quiet pool. He assumes he can easily hold his breath for a comfortable long time. Carbon dioxide starts building up in his blood triggering strong discomfort. His brain begins sending urgent signals demanding immediate oxygen intake. Diaphragm muscles start involuntarily contracting forcing urge to breathe. Vision begins to blur slightly as oxygen levels continue dropping. Heart rate increases rapidly trying to compensate for low oxygen supply. Body enters panic response overriding conscious control of breath holding. He involuntarily inhales water or air causing sudden forced recovery reaction. Body resets breathing automatically once oxygen flow is restored safely.
