How a man die by taking breath
Answers
Explanation:
Voluntarily holding your breath will eventually lower the oxygen content of arterial blood. Although breathing is normally regulated by blood CO2 levels, that feeling of extreme urgency to breathe after prolonged, deliberate breath-holding is due to hypoxia.
Eventually you lose consciousness as the brain loses oxygen, so you simply stop holding your breath. Some of your deepest and most powerful reflexes, originating in the brainstem common to all vertebrates, are for breathing. Indeed patients under general anesthesia are often allowed to breathe spontaneously, even while completely unconscious. So if you pass out from hypoxia you immediately begin breathing again, keeping yourself from dying. That's the happy version.
While hypoxic, however, you are at risk from cardiac arrhythmias or brain seizures, either of which can potentially cause sudden death. When you lose consciousness you might fatally strike your head or break your neck. Once fallen, you might obstruct your airway and stop breathing despite the diaphragm contracting, which could rapidly lead to death given that you were already hypoxic before obstructing.
To say nothing of opioids or other drugs that inhibit the normal ventilatory drive, which is why people often die from opioid overdoses. If you deliberately hold your breath to the point of passing out, after taking prescription pain pills or even after one drink of alcohol, then I'd say all bets are off about low risk of fatality for such a stunt.
