Alcohol gas may lead to retarded brain cell development, allergic rhinitis and respiratory diseases such as asthma and cough. 1. Brain cell development retardation: wine gas has alcohol content, coupled with the relatively young age of infants, the body’s resistance to the outside world is relatively weak, this gas, if accompanied by infants for a long time, may lead to brain cell development retardation. 2. Allergic rhinitis: the respiratory tract of infants is not mature, so the mucous membrane of the airway and nasal cavity will be more sensitive, and if the contact with alcohol gas may lead to damage to the mucous membrane around the nasal cavity, which will cause allergic rhinitis in the long term. 3. Respiratory diseases: after exposure to alcohol vapor, the mucous membrane of the respiratory tract will be stimulated, and airway spasm may occur, causing respiratory diseases such as wheezing and coughing. There are other ways in which alcohol vapor can be harmful to babies, so it is recommended that babies should not be exposed to it after drinking alcohol.
