Eating a lot of cold drinks in a short period of time will cause sudden stimulation to the stomach, which will cause the blood vessels to contract sharply and cause convulsions. So the speed of eating cold drinks must be slow. In addition, it is best to eat only one at a time, at most two. Jane Yiping said that eating a lot of cold drinks is the most likely cause of acute gastritis, which usually manifests as vomiting and diarrhea. If you eat a lot of cold drinks for a long time, it will also reduce the digestive ability of the stomach and the defense ability against bacteria and reduce the resistance of the human body.
