In fact, a 1992 study by the Environmental Protection Agency says ETS causes 150,000 to 300,000 lower respiratory tract infections each year in infants and children under 18 months of age. These illnesses result in as many as 15,000 hospitalizations. Children of parents who smoke half a pack a day or more are at nearly double the risk of hospitalization for a respiratory illness. Inhaled smoke irritates the eustachian tube, which connects the back of the nose with the middle ear. This causes swelling and obstruction which interferes with pressure equalization in the middle ear, leading to pain, fluid and infection.
Ear infections are the most common cause of children's hearing loss.
When they do not respond to medical treatment, the surgical insertion of tubes into the ears is often required. Modest impairment in school performance and intellectual achievement have also been demonstrated. While these facts are quite alarming for everyone, you can stop your child's exposure to secondhand smoke right now. Stop smoking, if you do smoke. Consult your physician for help, if needed.
