Two of these factors, such as smoking and obesity can lead to hearing loss problems, scientists say. Scientists at the University of Antwerp believe that obesity and smoking hurt the flow of blood in the ears, resulting in deterioration of the hearing, but the highest risk factor is still a work in connection with the high noise level. Scientists have the study, which was attended by 4,000 men and women aged 53 to 67 years old. All participants tested the level of hearing and interviewed about their lifestyle. Experts have noted that the ability to hear high-pitched sounds in smokers and obese people was broken, but the largest proportion of hearing was with people whose work associated with high noise levels associated. According to researchers, hearing loss is proportional to the length of service smoking and body mass index. Hearing starts at an average of one year regular smoking worsens, experts say. But the problem is that if the hearing took place, the damage is irreversible.
