If the fan is blown for too long or too often, it will cause obvious abdominal pain, mainly due to the low temperature caused by the fan, resulting in spasmodic pain in the abdomen, which will lead to the strengthening of intestinal peristalsis and cause abdominal pain with corresponding symptoms such as nausea, vomiting, fever and even diarrhea when it causes gastrointestinal flu. Sometimes, appendicitis may also be triggered by simple spasmodic pain, so it is important to pay high attention to the symptoms that cause abdominal pain and go to the hospital in time to find out the exact cause through relevant auxiliary examinations, and then give symptomatic support treatment to relieve the symptoms of abdominal pain.
