Florida, one more proof that secondhand smoke increases risky similar to active smokers. Recent research has found that passive smokers at high risk of hearing loss Deaf.

Doctors and health experts have been widely known that smoking can cause hearing loss in active smokers. And a recent study in the journal Tobacco Control showed the same thing also happened on passive smoking.

In that study, researchers from the University of Miami and Florida International University tested more than 3,000 participants of non-smokers (active and former smokers had never smoked at all).

The results showed that passive smokers are also at risk of hearing loss hearing loss from exposure to the threat of cigarette smoke . even higher than the exposure to noise.

“We do not know exactly how much cigarette smoke that can increase the risk of hearing loss, but we know very low threshold.,” Said Dr. David Fabry, leader of the research.

According to Dr. Fabry, a safe level to eliminate risk completely exposed to smoke. Exposure to cigarette smoke and even increase the risk of hearing at all frequencies as much as threefold.

“We already know from our own research that active smoking regularly represents a significant risk factor causing hearing loss and the new study is important because it highlights the increasing risks posed by passive smoking as well.,” Said Dr Ralph Holme, biomedical research at the head of the RNID ( Royal National Institute for the Deaf).

Dr. Holme explains, cigarette smoke can cause disruption of blood flow in small blood vessels ear. This could lead to organs deprived of oxygen and increase the buildup of toxic substances, which eventually causes damage to the ear.

Dr Holme also said that the danger of hearing loss from cigarette smoke is different from hearing loss caused by noise exposure or due to aging.

“Hearing loss can often make people very frustrating and causes social isolation, if not treated quickly. Therefore, before you light a cigarette, you have to consider that the smoke can harm not only you but also friends and relatives,” concluded Dr. Holme .
