What Causes Allergies to Suddenly Get Worse?
Allergies can suddenly worsen due to increased allergen exposure, immune system changes, or environmental factors. Common triggers include higher pollen counts during peak seasons, new pets or dust mites in your home, and stress that weakens immune function. Hormonal changes during pregnancy or menopause can also amplify allergic reactions by up to 40%. Moving to a new location exposes you to different allergens your immune system hasn't encountered before. Age-related immune system shifts, typically starting around age 40, can cause previously mild allergies to become severe. Weather changes, air pollution levels exceeding 35 micrograms per cubic meter, and certain medications like ACE inhibitors can also trigger sudden allergy flare-ups.
