Why is Eczema So Common in Singapore? Mold Might Be The Cause.
Eczema is often triggered by common environmental factors that irritate the skin. Besides the clothes that we wear or the toiletries that we use, investigating your home for environmental triggers could help you manage eczema more effectively.
MOLD → THE OFTEN INVISIBLE CULPRIT
Multiple research studies often speak about the doubled risk of childhood eczema when there are mold or damp stains in the children's room. Having composite wood, rich wood, or cement flooring at home tend to be significantly associated with childhood eczema. Why does this happen? These materials tend to have greater hygroscopicity (i.e. absorbs more moisture from the environment), which leads to invisible micro-mildew, especially in hot and humid cities. Fungi in the mildew could become allergens, stimulating the body to produce specific immunoglobulin E (IgE), thus causing allergic dermatitis e.g. eczema.
DOES YOUR HOME HAVE...
Laminate Flooring?
Mold often develops under the planks. Most laminate floors are installed over a wooden subfloor (though some are laid directly on concrete). Sometimes, there may be a problem with the concrete subfloor, such as water damage or uneven flooring. This can result in moisture building up under the laminate floor, causing mold growth beneath. Even if the concrete is properly installed, some laminate floors may contain hidden gaps, which can let moisture leak through.
Hardwood Flooring?
Mold may be growing beneath it if you notice dark stains or discolouration on the top of your hardwood floor. Warping or buckling floorboards are also a warning sign that moisture is trapped beneath. Or if your wooden floor is flaking or peeling, it's a sure sign that moisture from the mold is breaking down the adhesive bonds between your floors and their protective coating.
A History of Leaks?
Given Singapore's frequent wet weather, you might have experienced some form of leaks at home. Or maybe a problematic air-conditioning unit at home could have exposed your flooring to excess moisture. Whether it's condensation, steam, or high humidity, these all encourage mold to grow in our homes or offices. Certain types of mold, such as black mold produce chemicals called mycotoxins which are commonly associated with “Sick Building Syndrome”. Besides bedrooms, you also need to be careful about the mold growth in your bathrooms and kitchens -- often areas of high dampness. 
Does your family struggle with sinus infections, or does your child have childhood asthma or simply wake up sneezing each day? Beyond atopic dermatitis (a.k.a. eczema), allergic rhinitis (i.e. sinus problems) has also been significantly associated with mold. A study in South Korea confirmed this, especially since excessive moisture (dampness) and water damage in residential complex buildings often occur due to frequent heavy rain and typhoons.
As you manage your eczema or sensitive skin problems, don't forget to do thorough checks of your home. It may just be the missing factor in the mystery of why eczema is in your family.
