Why does a child have a fever at night?

There may be many reasons why a child may have a fever at night. The following will analyze the possible reasons from a biological and medical perspective. 1. Biological explanation The human body\’s biological clock will affect changes in body temperature. Generally, the human body\’s body temperature will be lowest in the morning and highest at night. This is because the body\’s internal biological clock controls various physiological processes in the body, including changes in body temperature. Therefore, if a child has a fever at night, it may be because the body temperature is already relatively high at night, and the fever causes the body temperature to rise further. 2. Medical explanation In addition to biological factors, children\’s fever at night may also be caused by certain physical problems. Here are the possible causes: Infection Infection is one of the most common causes of fever. Infections can be caused by bacteria, viruses, or fungi. Children may get respiratory infections (such as colds, flu, pneumonia), urinary tract infections, gastrointestinal infections, etc., which may cause fever. If your child\’s fever is accompanied by other symptoms, such as cough, runny nose, diarrhea, etc., then infection is more likely. Allergies Allergies may also cause fever. If your child has allergy symptoms, such as rash, shortness of breath, headache, etc., then a fever is possible. Allergies may also cause fever because the body mounts an immune response to the allergen, causing the body temperature to rise. Autoimmune Diseases An autoimmune disease is a disease caused by the immune system attacking one\’s own tissues or organs. These diseases may cause fever, such as rheumatic fever, systemic lupus erythematosus, etc. The latest and most complete 2023 [Kindergarten, Junior High and High School] premium VIP course catalogs from famous teachers in various disciplines on the entire network, click to view now!
