[Breeze] Why can the "Fright Method" stop hiccups?
Hiccups are mostly caused by eating too fast, swallowing cold air, mood changes, etc. When these stimuli are transmitted to the brain, the brain will issue instructions, so that the diaphragm appears spasmodic contraction, air is quickly sucked into the lungs, and the fissure between the two vocal cords suddenly narrows, which will cause hiccups.
As a strong emotional stimulus, fright can be transmitted through the cortex to the subcutaneous center, inhibiting diaphragm spasm. Therefore, the "scare method" can really stop burping. Similarly, holding your breath, taking a few sips of warm water, and exhaling into a paper bag can all help.
But for people who originally have cardiovascular and cerebrovascular underlying diseases, do not choose the method of sudden fright.
