How Are Weather and Seasonal Allergens Connected?

According to experts in allergy, asthma and immunology, weather can significantly affect the symptoms in people with seasonal allergies. Depending on the allergen causing a reaction, the best weather conditions for allergic people may differ.


Weather and Pollen Counts


In many cases, pollen allergy sufferers feel more comfortable on cool, rainy days or the days right after rain. The cooler the weather, the slower is the growth of plants.

Specialists say that for people with pollen allergy, the weather on rainy days in the best, since the rain helps to wash the pollen out of the air. However, this is only a temporary effect because it also helps plants grow.

The weather often gets dry and sunny several days after rain, which even increases the pollen counts in the air, making the symptoms of many allergy sufferers worse. Such a weather allows the plants, especially those in their peak season, to produce pollen.

When the weather is windy, the pollen can easily spread and reach the areas many miles away, which typically happens in the middle of a pollen season. On windy days, the levels of mold spores also increase.

Climate and Pollen Counts


Allergists suggest that places where the climate tends to be hot and dry provide more favorable conditions for people allergic to pollen. There is usually a lack of plants in such places, which means that the pollen levels are lower.

However, dry and hot climates are typically associated with dust that causes sneezing and runny nose, as well as red, itchy or watery eyes in people allergic to dust mites.

Peak Seasons for Different Types of Pollen Allergies


People with pollen allergies can be allergic to the pollen of particular plants, such as trees or weeds. Since trees, weeds and grasses produce pollen during different seasons, people with seasonal allergies may see an increase in their symptoms at different times.

Spring is often the worst time for those allergic to pollen, especially tree pollen. Tree pollen season usually starts in middle of the spring. In addition, grass pollen is a dominant throughout the summertime, while weeds tend to produce pollen during late summer and early fall.

The best times of the year for people with seasonal allergies are usually in winter, early spring or late fall. The allergy season normally ends in fall or winter, once the plants get frozen.

What About Allergens Like Mold and Dust Mites?


People affected by mold allergy or allergy to dust mites often experience worsening of their symptoms in humid and wet surroundings. Mold spores and dust mites are among the most common allergens, but dust mites are more likely to cause a reaction, as these are an indoor allergen. Unlike outdoor allergen like pollen, indoor allergens usually affect you more during the fall and winter, mainly because people spend more time inside.
