Environmental allergens are a well-documented common trigger for exacerbations in patients with eczema, also known as atopic dermatitis. Allergens such as dust mites, pollen, pet dander, and mold can provoke inflammatory responses leading to worsening of eczema symptoms. The immune system of individuals with eczema often overreacts to these substances, resulting in increased pruritus (itching), redness, and flare-ups of the skin condition.

In contrast, excessive moisturizing is typically a preventive measure in managing eczema rather than a trigger; it helps maintain skin hydration and barrier function. Complete sunlight exposure can have varying effects on eczema, with some patients experiencing improvement due to the anti-inflammatory properties of UV light, while others may find sunlight irritating. Infrequent bathing is also generally not a trigger; rather, regular, gentle cleansing can be beneficial. Proper bathing techniques, including the use of lukewarm water and applying moisturizer afterward, are crucial in eczema management.
