Secondhand smoke has become the "killer" of children's respiratory health. What diseases can long-term contact lead to?

Long-term exposure to secondhand smoke may cause harm to children's respiratory system and immune system. 1, respiratory diseases. If either parent smokes, the risk of children suffering from respiratory diseases, lower respiratory diseases and wheezing diseases is higher than that of children whose parents don't smoke, and the mother's smoking has a greater impact on children. 2, otitis media. According to the report of the American Health Director, the risk of children whose parents smoke is 1.0- 1.5 times higher than that of children whose parents don't smoke. If either parent smokes, the risk of children suffering from recurrent otitis media is higher than that of children whose parents don't smoke 1.37 times. 3, allergic diseases. As early as 198 1, the authoritative medical journal The Lancet first suggested that exposure to second-hand smoke might increase the body's allergic sensitization. 18606 a study of the international children's asthma and allergy research shows that children whose family members smoke more than 50 cigarettes at home every day have 2.90 times the risk of allergic rhinitis compared with children who do not smoke passively.
