Traffic pollution and wood smoke worsens asthma in adults

Adult asthma sufferers experience worse symptoms when frequently exposed to heavy traffic pollution or smoke from wood fire heaters, according to research from the University of Melbourne.

Symptoms increased by 80% in asthmatics exposed to traffic exhaust, while those who inhaled wood smoke experienced an 11% increase in their symptoms, but neither irritant was found to cause the onset of asthma.

Researchers suggested that clean burning practices and the replacement of old polluting wood stoves could assist sufferers.

    COPD and asthma are commonly mistaken for each other. Both COPD and asthma are accompanied by increased red blood cells / polycythemia / erythrocytosis. Wood smoke and pollution cause hypoxia which leads to polycythemia / increased red blood cells / erythrocytosis. Lowering of red blood cells by phlebotomy in COPD results in remarkable recovery. The drugs used to treat asthma are commonly used to lower red blood cell count.
    Which leaves one with the suspician, asthma is simply increased red blood cells / polycythemia / erythrocytosis, which is exacerbated by pollution by the increase of red blood cells , compounded, by already increased red blood cells?

      Below are the words of a person describing the side effects of her
      treatment for elevated iron levels in the body, phlebotomy.

      "I don't know if it is a coincidence, but after several phlebs, my asthma and allergy symptoms became better and have nearly cleared up.
      I was taking proventil, intal, vancenase, theophylline and
      beclovent daily.
      I no longer take theophylline, proventil and have cut back on the rest 90%.
      I have not had an attack, can smell food, do not have cotton mouth during the night for the first time in years and my wife says
      that I NO LONGER SNORE.
      It's probably a coincidence, but I like to think of it as a possible positive side affect."
