Another reason to quit smoking: Current smokers were up to 70 percent more likely to develop high-frequency hearing loss than non-smokers, according to a Japanese study. Published in the journal Nicotine & Tobacco Research, the study included more than 50,000 Japanese participants (ages 20–64) who did not have hearing loss at baseline.
As part of the Smoking, Smoking Cessation, and the Risk of Hearing Loss: Japan Epidemiology Collaboration on Occupational Health Study, researchers tracked the cohort for eight years, performing hearing testing annually.
The high-frequency hearing loss risk increased with the number of cigarettes smoked per day:
  • Up to 10 cigarettes a day equated to a 40-percent increased risk.

  • 11–20 cigarettes a day equated to a 60-percent increased risk.

  • More than 20 cigarettes a day equated to a 70-percent increased risk.

The high-frequency hearing loss risk increased with the number of cigarettes smoked per day.
“These results provide strong evidence to support that smoking is a causal factor for hearing loss and emphasize the need for tobacco control to prevent or delay the development of hearing loss,” says lead author Huanhuan Hu, a researcher at Japan’s National Center for Global Health and Medicine.
