Dust and environmental allergens
There are a lot of reasons to want to keep a dust-free home. Dust is tough on the lungs as well as the skin. The National Eczema Society explains that it’s not dust mites but rather their droppings to which people can be allergic. If you are allergic to these and have eczema, you’ll see a flare-up in a dusty home. Other allergens in the home such as pollen or pet dander can also make eczema flare up. Unfortunately, the process of cleaning these away can cause the particles to land on the skin or get in the lungs, which is why it’s important to wear long rubber gloves and possibly a mask when dusting your home.
