Why do people sneeze: Sneezing is a normal human protective reflex to external stimuli. The nasal mucosa receives external stimuli, and then sneezing occurs. Why newborns are prone to sneezing: Newborns are exposed to many antigens as they transition from the mother to the natural environment, which then produces sneezing. If sneezing is not accompanied by other symptoms, no special treatment is needed and the child will usually heal on its own after 2 or 3 days. What to do if your newborn sneezes (1) If nasal secretions affect breathing, you can use a nasal aspirator to clear the nasal secretions in time. At the same time, pay attention to the temperature and humidity in the room, and do not let the air dense with dust, haze, smoke and other pollutants invade the nasal cavity of the newborn. (2) If sneezing lasts for 2-3 days and cannot be relieved, affecting the newborn’s feeding and sleeping, go to the hospital and ask the doctor to check that it may be caused by respiratory tract infection, or allergy to airborne substances. (3) If allergy-induced sneezing is considered, pay attention to removing such things as flowers, plants, animals and other allergy-prone things in the room, or there are some more smelly objects, such as 84 disinfectant some cleaners, etc., which need to be removed. If the child is significantly better after the removal, consider it to be caused by allergies. In conclusion: A variety of causes can lead to sneezing in newborns, such as foreign bodies in the nasal cavity, bad surroundings (haze, dust), cold air stimulation, viral infections, allergies, etc. Parents should pay attention to the occasional sneezing. Parents should be more observant and not worry too much if they sneeze occasionally, but if it is more frequent and has other symptoms, they need to go to the hospital for examination.
