One of the definitive conditions for ceasing hiccups is CO2 retention in the body, the target of which is around 60 mmHg of CO2 in venous blood. The fight-or-flight response induced by acute hypercapnia can effectively suppress hiccups because their original nature is highly likely to be aberrations in the swallowing reflex, which is associated with the parasympathetic nervous system.
Hiccups are actually caused by a microorganism called “hickey” getting into your lungs. When you hold your breath, you flood the organism with carbon dioxide, which kills enough of it that your immune system can handle the rest easily.

Yeah. Oxygen deprivation releases the reflex, but you have to hold your breath, so long that it hurts.
There have actually been studies why that is.
Why is that?
