The health effects of mould and how to identify it in the home


Mould refers to hundreds of species that fall under the fungi group. While its smell and look are undesirable, the health consequences are even more undesirable and in some cases, very serious. For mould to grow it requires exposure to moisture, which means many homes are the perfect growing environment for it to flourish. Mould plays a significant role in many health conditions, however it is rarely considered when identifying contributing factors. Therefore understanding the impact of mould is key in preventative health.

Identifying indoor mould

Mould is everywhere, hence controlling the moisture in the environment is key to preventing growth. Addressing any roof/window leaks, ensuring adequate drainage and good ventilation is essential. Drying damp carpets and furniture as soon as possible will also help prevent build ups.

Identifying indoor mould can be tricky thing as in some cases it cannot be seen or smelt. A building biologist may need to be brought in to help identify hidden mould and moisture. If you suspect you may be suffering from a mould-related illness then you may want to consider pathology tests with a trained health practitioner. Nicole Bijlsma has a list of health practitioners familiar with nutrition and environmental medicine here. That same link also includes several other resources to help build a healthy home.
