The nasal allergic condition is known as allergic rhinitis and it can be triggered by indoor or outdoor allergens. Some people have both, indoor and outdoor allergies. The common outdoor allergens include pollen from grass, trees, ragweed, weeds and mold spores. The indoor allergy triggers are mainly in the form of dust mites, pet dander, cockroaches and mold spores.

Short term rain is a blessing. The outdoor pollen usually settles down with rain and it spells relief for many allergy sufferers. Ongoing rain, followed by dry, warmer weather allows higher amount of pollen to circulate in the air which will increase allergy symptoms. If the moisture from the rain is allowed to affect the home or indoor environment, it can increase mold growth, exposure and allergy symptoms.

The mold and mildew needs dampness and gets worse in the basement, bathrooms and in the areas with the water leaks. Continued running of humidifiers despite the high moisture in the air during the rainy days, will add the possibility of mold growth. The dust mites found in the mattress, pillows and the carpet love humidity for their survival and growth. Ongoing high moisture will also increase dust mite exposure.

The tips to help reduce the allergy symptoms in rainy weather.

1, Manage humidity in the home environment. The aim is to bring the humidity around 40 to 50%.
Running dehumidifiers, especially in the basement, can be very helpful. This will reduce the mold growth.

2, Avoid carpet on the concrete or damp areas

3, Reduce clutter and do not store in the damp areas

4, Identify, repair and seal all the leaks to minimize dampness

5, If mold is present, get the professional help

6, If you need to handle stored items with visible mold growth, use a mask and protective gears

Some of the allergy sufferers also have non allergic rhinitis that gets worse with irritants. Some patients experience increased sinus pressure and nasal symptoms due to the high humidity, mainly due to associated non allergic rhinitis. Your allergy specialists can recommend the best options for you.
