When it comes to chronic bronchitis, everyone seems to put the blame #1 on smoking (past or present).<\/p>\nWhen it comes to chronic bronchitis, everyone seems to put the blame #1 on smoking (past or present).<\/p>\n
Yeah, we all know smoking is bad for you.<\/p>\n
But your workplace carries almost 50% of the blame (whether you smoke or not), according to a new study in Occupational & Environmental Medicine<\/em>.<\/p>\n And you can heal it without changing your workplace\u2014or even without stopping smoking.<\/p>\n Most of us spend a third of our adult lives at work, breathing whatever is in the air around us.<\/p>\n For some occupations, this means regular exposure to chemical vapors, gases, dusts, and fumes (VGDF) that can irritate and damage our lungs over time.<\/p>\n Researchers wanted to understand just how much these workplace exposures might contribute to chronic bronchitis.<\/p>\n The research took place in Telemark County, a region in southern Norway.<\/p>\n It included over 20,000 people between the ages of 16 and 55. The scientists used a two-step process:<\/p>\n 2.\tThen, they matched participants\u2019 job titles with the Nordic Job Exposure Matrix (N-JEM) tool. This tool helps identify what substances people are likely exposed to in different occupations.\n<\/dd>\n<\/dl>\n Chronic bronchitis was defined in this study as a cough that brings up mucus and lasts for at least three months a year for two years in a row.<\/p>\n After collecting all this information, the researchers analyzed the data, accounting for important factors like age, sex, and smoking status that could affect the results.<\/p>\n Their findings were shocking:<\/p>\n 2.\tPeople who reported daily exposure to VGDF were 3.6 times more likely to have chronic bronchitis than those without exposure.<\/p>\n 3.\tEven occasional workplace exposure to VGDF increased the risk by 1.6 times.<\/p>\n 4.\tAmong people who had smoked at some point, the link between job-related irritants and bronchitis was particularly strong.<\/p>\n 5.\tUsing the job exposure matrix (rather than self-reports), chronic bronchitis was still clearly connected to irritants. But only among smokers.<\/p>\n 6.\tAccording to the job exposure matrix, among ever-smokers (current or former), those with workplace exposure to irritants were 1.4 times more likely to have chronic bronchitis.<\/p>\n 7.\tThe researchers estimated that workplace exposure was responsible for 41% of all chronic bronchitis cases \u2014 49% among people who had smoked and 37% among those who never smoked.\n<\/dd>\n<\/dl>\n If you work where you\u2019re regularly breathing in dust, gas, fumes, or chemical vapors (think construction, cleaning, manufacturing, or even hairdressing), you might want to wear a mask and campaign for better workplace ventilation.<\/p>\n Now that we know why you suffer from chronic bronchitis, let\u2019s look at how to heal it.<\/p>\n\n
