  • There are many harmful effects of smoking
  • Smoking may also lead to a loss of hearing
  • For smokers, it can get difficult to listen to low-frequency sounds

Smokers beware. You may be at a higher risk of suffering hearing loss, as a new study suggests that smoking affects the ability to hear both high and low-frequency sounds.

“These results provide strong evidence to support that smoking is a causal factor for hearing loss and emphasise the need for tobacco control to prevent or delay the development of hearing loss,” said lead author Huanhuan Hu from the National Centre for Global Health and Medicine in Japan.

For the study, published in the journal Nicotine and Tobacco Research, researchers included 50,195 people, aged between 20 to 64 years and free of hearing loss.

The researchers analysed data from annual health checkups, which included audio testing performed by a technician and a health-related lifestyle questionnaire completed by each participant.

They examined the effects of smoking status (current, former and never smokers), the number of cigarettes smoked per day, and the duration of smoking cessation on the extent of hearing loss. The participants were followed up for a maximum of eight years.

Even after adjusting for factors including occupational noise exposure, researchers noted a 1.2 to 1.6 increased risk of hearing loss among current smokers compared with never smokers.

During follow-up, 3,532 individuals developed high-frequency hearing loss, and 1,575 developed low-frequency hearing loss. While the association between smoking and high-frequency hearing loss was stronger than that of low-frequency hearing loss, the risk of both high and low-frequency hearing loss increased with cigarette consumption, the researcher said.

The increased risk of hearing loss decreased within five years after quitting smoking, the researcher added. “With a large sample size, long follow-up period, and objective assessment of hearing loss, our study provides strong evidence that smoking is an independent risk factor of hearing loss,” Hu said.

Japan Bans Smoking Inside Public Facilities, Seen By Critics as Pointless

Japan on Wednesday approved its first national legislation banning smoking inside public facilities, but the watered-down measure excludes many restaurants and bars and is seen by critics as toothless.

The legislation aims to lower secondhand smoking risks ahead of the 2020 Tokyo Olympics amid international calls for a smoke-free event. But ruling party lawmakers with strong ties to the tobacco and restaurant industries opted for a weakened version.

The upper house approved and enacted the bill into law Wednesday after it was approved earlier by the lower house.

Last month, Tokyo separately enacted a stricter ordinance banning smoking at all eateries that have employees, to protect them from secondhand smoke. The ordinance will cover about 84 percent of Tokyo restaurants and bars.

But the law still allows many exceptions and the Tokyo Games may not be fully smoke-free.

Japan often has been called a smokers’ paradise. Until now it has had no binding law controlling secondhand smoke and ranked among the least protected countries by the World Health Organization. That has brought pressure from international Olympic officials.

The new national law bans indoor smoking at schools, hospitals and government offices. Smoking will be allowed at existing small eateries, including those with less than 100 square meters (1,076 square feet) of customer space, which includes more than half of Japanese establishments. Larger and new eateries must limit smoking to designated rooms.

Violators can face fines of up to 300,000 yen ($2,700) for smokers and up to 500,000 yen ($4,500) for facility managers.

The law will be implemented in phases through April 2020.

‘Too lenient’

The law allowing smoking at more than half of Japan’s restaurants as exceptions is inadequate, said Hiroyasu Muramatsu, a doctor serving on Tokyo’s anti-smoking committee. “The law is too lenient compared to international standards,” he told Japan’s NHK public television. “We need a full smoking ban.”

The health ministry’s initial draft bill called for stricter measures but faced opposition from lawmakers sympathetic to the restaurant industry. The government also was viewed as opposed to harsher measures because the former monopoly Japan Tobacco is still partly state-owned.

In Japan, almost a fifth of adults still smoke. The rate for men in their 30s to 50s is nearly twice as high, according to a government survey last year.

Most office workers now light up only in smoking rooms or outdoors, and cities are gradually imposing limits on outdoor smoking in public areas. But most restaurants and bars in Japan allow smoking, making them the most common public source of secondhand smoke.

“Secondhand smoking has been largely considered an issue of the manners, but it’s not,” Kazuo Hasegawa, 47, a nonsmoker who has developed lung cancer, told NHK. “It’s about health hazards. It harms people. And I don’t want younger generations to have to suffer like me.”

In Japan, about 15,000 people, mainly women and children, die annually as a result of secondhand smoke, according to government and WHO estimates. (VOA)
