An expert from Action on Smoking and Health (Ash) has reminded parents of the importance of protecting their children from second-hand smoke, after research suggested a possible link with hearing loss.
Martin Dockrell - director of research and policy at Ash - observed that numerous studies have pointed to a correlation between passive smoking and a wide range of health problems.
"There is already a lot of evidence about the harm caused to children, particularly younger children, from second-hand smoke," he said. "It is important to protect your kids."
Mr Dockrell added that while kicking the habit altogether is perhaps the best way of shielding youngsters from passive smoking, the most effective way of quitting successfully is to do so in tandem with a partner.
Earlier this month, a study published in the Archives of Otolaryngology - Head and Neck Surgery journal suggested the level of exposure to second-hand smoke appeared to be directly related to the extent of low-frequency deafness.
