Rubbing alcohol in the nostrils is not recommended. Because alcohol has a strong irritant, it can not only kill bacteria can also damage the normal nasal mucosal cells, the mucous membrane in the nostrils caused by damage, thus weakening the barrier protective effect of the nasal mucosa. It affects the cilia movement of the nasal mucosa, leading to nasal secretion retention, and if it leads to damage to the nasal mucosa in the olfactory region, it will also cause a weakened sense of smell. If it is necessary to clean the nasal mucosa or deal with nasal secretions, saline can be used instead; if you want to disinfect the nasal mucosa, you can use iodophor and other disinfectants that are less irritating to the mucosa to disinfect the nasal mucosa. In addition, it is recommended that patients should have a light diet in their daily life, and go to the ear, nose and throat of regular hospitals in a timely manner when nasal discomfort occurs, so that professional doctors can give regular medication and treatment, and do not blindly deal with it on their own, so as not to cause serious consequences.
