Have you ever wondered why sometimes your allergies flare on windy days, or your allergy symptoms get worse after it rains? The truth is that the weather can affect your allergies in different ways, depending on what you are allergic to.

How the Weather Affects Your Allergies

If you are allergic to dog or cat dander, your allergies might flare up more during the winter when most people tend to keep their pets indoors and spend less time outside. Most people also tend to turn on their heater at home, which causes some pets to shed more during the winter months.

If you are allergic to mold, rainy or humid days can make your allergies worse. Moisture helps mold grow both indoors and outdoors.

For those allergic to dust mites, humid days can also make their allergies flare up because dust mites thrive in humid environments.

For those with allergic asthma, the hot summer days can bring about asthma attacks because the ozone and smog is a serious trigger.

The weather can especially influence the allergic reactions for those allergic to pollen. Weather conditions can determine the amount of pollen production throughout the year. For example: a mild winter can signify an early Texas allergy season because the trees tend to start pollinating earlier than usual, while a long winter can delay pollen production.

While humidity can be good for pollen allergies because it weights down the pollen and keeps it on the ground, rainy days can actually mean worse allergy symptoms for those allergic to pollen. Rain tends to burst pollen particles, releasing them into the air at a much higher concentration.

Dry wind can wreak havoc for those allergic to pollen. The wind tends to blow the pollen particles into the air and spread them around more easily, sometimes causing chronic dry nose. If you have pollen allergies, shut the windows and stay indoors on windy days.

The weather is ever changing and it is sometimes hard to predict, which is why it is important to treat the root of your allergies in order to be able to enjoy your time in and outdoors no matter what the weather brings.
