Hot Weather Means More Asthma

Posted on June 17, 2014

It’s getting hot here in Southern California and it’s going to get hotter. And it’s usually worse than the meteorologists predict.

Studies reported in the journal Nature, “have linked temperature increases to greater amounts of pollen and mold. These are some of the primary triggers of asthma. This is because asthma is triggered by an allergic reaction. When something such as pollen is inhaled, the person’s airwaves constrict. This makes breathing hard and an inhaler is required to ease the pressure.”

With higher temperatures worldwide comes higher humidity–damp–and what comes with damp? Growth of mold and bacteria. Mold spores and bacteria cause illness, allergies and asthma, which can be deadly.

As temperatures rise worldwide, the risks that come with them increase both in severity and area. It’s hot here, but what if our climate extended into Northern California and beyond, where temperatures are much lower even in the height of summer? What if it weren’t hot in the upper midwest only in August but for an extended period? And combined with humidity from the Great Lakes? They are already getting more snow because of increased moisture in the air in the winter due to climate change.

The Environmental Protection Agency has researched the connection between asthma and climate change and “concluded that more carbon dioxide in the atmosphere and increased rainfall had led to increased levels of pollination. This was driving the constant growth of people suffering from asthma.”

There is no doubt that asthma cases are growing in number in the US and all over the world. Higher levels of particle pollution, continued use of chemicals and cleaners which add volatile organic compounds to our air and our dependence on fossil fuels are certainly factors. But higher temperatures are a valid concern as well.
