In the fall, there is an increase of both indoor and outdoor allergens. The most common indoor irritant is mold spores.

People with asthma may be impacted by their seasonal allergies. Allergic asthma or allergy-induced asthma can flare up when you are exposed to substances to which you are sensitive.

People with eczema also can experience increased flare ups due to exposure.

Is it possible for a person’s
allergy symptoms to vary over time?
Yes, your allergies can fluctuate over time. Experiencing different environments while traveling may lead to allergy changes when you’re exposed to new allergens. Moving to a different region may cause an increase or decrease in symptoms depending on the mix of vegetation in your new home. Sometimes, it can take time for symptoms to develop. For example, pollen allergies usually take a few seasons to manifest because it takes exposure to become sensitized. Reactions to indoor allergens usually manifest sooner because the exposure is more consistent.

Are there ways to manage seasonal allergies without medication?
Allergies are your immune system’s inflammatory response to a foreign substance. They happen seasonally when your body overreacts to something airborne in the environment, usually pollen or mold. To avoid sneezing, congestion, a runny nose and other bothersome symptoms, there are simple steps you can take to manage your exposure to allergens.

How can I tell my allergies apart from a cold, the flu or COVID-19?
The common cold, seasonal allergies and COVID-19 can sometimes manifest in similar ways, especially now that vaccines and new variants are resulting in milder cases of COVID-19. Despite some indistinguishable symptoms, there are some key differences. Think about your history and consider what symptoms you’ve previously experienced in the fall. If you’re dealing with a fever, aches and pains, nausea or a sore throat, odds are it’s not your allergies making you sniffle and sneeze. Allergy symptoms also tend to last longer than the common cold.
