Farm life is bad for your lungs

For many, "life on the farm," represents a simpler, healthier life than a less natural, urban existence. But a recent study finds that, in fact, the truth is just the opposite.

Australian researchers found that farm workers have a higher risk of developing chronic obstructive pulmonary disease (COPD) -- a term given to a combination of lung conditions most commonly found in smokers.

No one knows for certain what aspect of farming might cause this correlation, but it isn't the first time the occupation has been linked to lung disease. Farmers have traditionally had a higher rates of asthma and lung cancer, for instance -- both of which may be caused by the inhalation of pesticides and other chemicals used in maintaining crops and livestock. There's also the "agricultural dusts" that farmers inhale. These organic materials from both animal and plant sources are known to cause inflammation in the airways.

It's hoped that with further research, doctors and scientists can understand exactly what's causing these health concerns.
