Asthma, eczema and hay fever are all linked to one another. Having one badly can lead to either of the other two emerging too and all are stimulated by the environment and the allergens within it. All three conditions can be contracted very early in life or, less commonly later in life and all have been positively affected by the butterfly effect I mentioned.
Around six years ago in 2007 and in the United Kingdom the smoking ban was put into place. This prevented from smoking in certain places. Anywhere public was put off limits to smokers, this included airports, stations, bus stops, bars and eateries of all kinds and pubs. The English pub was long known for its heady, smoky atmosphere and this all changed very quickly!
This ban has decimated the number of admissions into ER’s for asthma related symptoms by kids. The total, which was on the rise until 2007, plummeted and has continued to plummet since then. Obviously the kids in question weren’t smoking themselves but by removing the chance of second hand smoke inhalation, or at least diminishing it we’ve actually destroyed one of the biggest allergens for asthma.
This benefit wasn’t expected, or at least it wasn’t to such an amazing extent. Scientists are monitoring the levels as they continue to decline.
