Sneezing is a normal physiological response of the body to external irritants, to remove foreign bodies from the nasal cavity. When our nasal mucosa is stimulated by the cold air outside, especially in newborns, it is not only more sensitive but also more fragile. If you find that your newborn baby keeps sneezing without other cold symptoms, you need to pay attention to whether the room temperature is low and pay attention to raising the room temperature to keep your baby warm. When the temperature rises, the baby still sneezes easily. Observe whether the environment your newborn is in is dirty and messy. The air is dense with dust, smoke and other pollutants that can invade your newborn’s nasal cavity and make them start sneezing. Pay attention to timely cleaning and keep the room clean and not too dry. Sneezing is a normal physiological response to stimulation of the area between the human nasal mucosa and the throat. The nasal mucosa is very sensitive to external stimuli, especially for newborns. Therefore, sneezing in newborns is also a protective reaction. Don’t be nervous when it occurs, observe the causes of sneezing in your life and correct them in time, and don’t rush to give your baby oral cold medication, etc. Pay attention to other symptoms first, and if necessary, go to the hospital for examination and treatment.
