Here you are going to understand could noise be a risk factor for high blood pressure a Recent study investigated the relationship between occupational noise induced hearing loss and blood pressure The authors conclude that chronic the noise exposure increases the risk of hypertension According to the new paper Globally more than 600 million people have jobs that expose them to hazardous noise levels This high number makes noise exposure one of the most common workplace hazards In line with this occupational noise induced hearing loss is the most prevalent job-related condition in the United States Over recent years scientists have shown that noise exposure does not only affect hearing For instance studies have concluded that exposure to noise might negatively influence the cardiovascular health and even digestive health The authors of the recent study which features in PLoS ONE decided to focus on its effect on hypertension Noise exposure and blood pressure are currently more than 100 million adults in the u.s Have high blood pressure For this reason alone, it is important to understand any factors that might increase risk Earlier studies have investigated links between noise exposure and hypertension. But so far the findings have been inconsistent The authors of the current study believe that this is partly because it is difficult to quantify total noise exposure over decades To address this issue. The researchers used the hearing loss as a marker for noise exposure The authors explained several studies have reported that bilateral high-frequency hearing loss is associated with cumulative Occupational noise exposure and can serve as an early biomarker for the actual personal exposure to occupational noise The scientists had access to data from 20 1403 workers with occupational noise exposure in an average age of 40 years This information came from a survey of workers in Chengdu Sichuan Province in China as part of the survey the officials assess various health metrics using audiometric tests and measuring blood pressure a Significant association as expected the prevalence of hearing loss increased in tandem with the number of years that the participants had spent working with occupational noise exposure Overall the researchers found that workers with mild and high pH fhl had an increased hypertension risk of 34% and 281 percent respectively The present study suggested that occupational noise exposure was positively associated with blood pressure levels and hypertension risk They also report that a dose-response relationship between BH fhl and hypertension was found in both males and females in This study the authors found that the link between noise exposure and hypertension was most pronounced in men They believed that this might be because male workers are Usually exposed to higher noise intensity in their workplace compared with female workers similarly, the scientists used both VHF HL and duration of work to assess noise exposure The authors believe that this tandem approach might strengthen the effectiveness and credibility of the results by mutual confirmation However, there are certain shortfalls Firstly as the authors recognize because the study is Cross-sectional meaning that the team did not track the participants over the years. It is not possible to prove cause and effect Also, the authors note that their analysis could not account for some variables that affect hypertension risk These include body mass index BMI, the smoking status alcohol intake and psychological factors in addition The researchers did not visit workplaces to assess actual noise levels and they did not have any information on whether the participants used any defenders Although this study concludes that noise exposure effects blood pressure other studies have not found the same relationship Despite this study’s size scientists will need to carry out more work before noise exposure becomes an official risk factor for hypertension Hope you had enjoyed this session and getting the value for your time spend We are excited to have some suggestions from you and willing to see you again in our next video with a promise to bring more useful content Don’t forget to subscribe our channel if not subscribed yet and get the regular update for future videos Thanks for your time and wish you a healthy and wealthy life
