The simple answer is, yes. There are three simple reasons.
3 reasons that drought makes your allergies worse
First, the lack of moisture leads to more dust and dirt in the air. You may notice this on your car or the windows of your house or office. This same dirt gets in your nose and sinuses and leads to irritation.
The second reason is that plants and weeds still produce pollen, even in a drought. Since there is little rain or moisture to knock this pollen to the ground, it tends to stay in the air and become an irritant, just like the dust and dirt.
