Your lungs work hard. Most adults take more than 20,000 breaths a day. But just how well your lungs do their job may be affected by the job you do.
Chemicals. Germs. Tobacco smoke and dirt. Fibers, dust, and even things you might not think are dangerous can damage your airway and threaten your lungs.
"The lungs are complex organs," says Philip Harber, MD, MPH, professor of public health at the University of Arizona in Tucson. "Occupational and environmental exposures can lead to scarring or fibrosis, asthma, COPD, and infection or cancer."
The good news: Many on-the-job lung dangers are preventable. Depending on your line of work, making certain changes can be key: Improve ventilation, wear protective equipment, change the way you do your work, and learn more about hazards, for examples.
Here are 10 jobs where precautions may help you avoid work-related lung damage.
Secondhand smoke has been linked to lung cancer. It remains a threat to workers in cities where smoking hasn't been banned in public places. Casino workers also can find themselves in a cloud of smoke.
No one's going to wear a respirator while serving martinis or dealing a blackjack game. Separating smokers from nonsmokers, cleaning the air, and ventilating buildings won't keep nonsmokers from being exposed.
Short of working to change policy, the best solution may be to find another job.
"Unfortunately, the individual worker has limited options," says Susanna Von Essen, MD. She's a University of Nebraska Medical Center professor of internal medicine in the division of pulmonary, critical care, sleep, and allergy.
2. Housekeeping and Cleaning
Some cleaning supplies, even so-called "green" or "natural" products, have harmful chemicals that have been linked with developing asthma.
"Cleaners are reactive chemicals, meaning that they react with dirt and also with your lung tissues," Von Essen says.
Some release volatile organic compounds, which can contribute to chronic respiratory problems and allergic reactions. Read labels and follow instructions.
Consider using "simple cleaning agents like vinegar and water or baking soda," Von Essen says. Open windows and doors to keep the area well ventilated, too.
3. Health Care
Doctors, nurses, and other people who work in hospitals, medical offices, or nursing homes are at increased risk for lung diseases such as tuberculosis, influenza, and severe acute respiratory syndrome (SARS).
