Detailed answer

Indoor pollutants such as dust, pet dander, mold, and volatile organic compounds (VOCs) can aggravate hand eczema. These pollutants can trigger allergic reactions or irritate the skin, leading to increased inflammation and itching. Additionally, poor indoor air quality, often caused by pollutants, can disrupt the skin's natural barrier function, making it more susceptible to irritants and allergens. To mitigate the impact of indoor pollutants on hand eczema, it is important to maintain a clean and dust-free environment, regularly ventilate the space, use air purifiers, and minimize exposure to known irritants and allergens.
