Hiccup

Hiccup is a physiologically common phenomenon, commonly known as snoring. Snoring is caused by diaphragmatic spasm contractions. In fact, the diaphragm is not a membrane that separates the chest and abdominal cavity, but a large piece of muscle. Every time it steadily contracts, our lungs take a breath; since it is controlled by the brain's breathing center, the muscles of the diaphragm will move regularly, our breathing can operate completely autonomously, and we don't need to be constantly Remember how to breathe. When snoring, the transverse diaphragm involuntarily contracts, air is quickly drawn into the lungs, and the fissure in the two vocal cords suddenly narrows, causing strange noises. We don't know why the diaphragmatic muscle contracted uncontrollably. Although most of the snoring is transient, some people continue to snoring.
