Rain, Rain, Go Away

How does the rain affect your allergies?




Are you tired of all the rain we have had so far this summer? Clearly, the rain can ruin pool parties, summer picnics, and baseball games, but is rain good or bad for your allergies? Actually, it is a little bit of both.


When it is dry outside, trees can release more pollen. In addition, the lower the moisture in the air, the more lightweight the pollen is allowing the wind to carry it further. When there are light showers, the pollen can be washed away and is less likely to carry in the wind offering temporary relief. However, heavy storms can cause the grass and weed pollen clumps to burst apart into smaller particles. These particles can be quickly dispersed in the air worsening allergy and asthma symptoms. Also, remember that mold loves damp conditions and dust mites love humidity. If you are allergic to dust mites or mold, frequent rains and/or high humidity can worsen your symptoms.


If the shower is mild, grab your umbrella and be grateful for the temporary decrease in pollen counts. If heavy downpours occur, you might want to stay inside to avoid spikes in grass, weed, mold, and dust mite counts.
