What is mould?

Mould is a type of fungus found in both indoor and outdoor environments, capable of producing a number of metabolites some of which are harmful to human health. Certain moulds can produce secondary metabolites called mycotoxins, which are under continuous study for their potential impact on human and environmental health.

Each mould species can produce multiple mycotoxins, and hundreds have been identified to date. Indoor mycotoxin contamination is increasingly recognised as a public health concern, particularly in developing countries, areas with poor housing infrastructure or limited regulation.

Why is module so problematic?

Mould often goes undetected in homes and workplaces. It doesn’t always have a strong smell, nor is it always black or clearly visible, therefore, it can often remain unnoticed for years. Furthermore, mould often grows in hard to access or obscure locations such as underneath carpets, inside wall cavities and insulation, inside vents and air-conditioning units and under floorboards.

Mould eradication: fact vs. fiction

Popular remedies such as vinegar, clove oil, bleach, or baking soda may offer short-term relief from surface mould on non-porous materials. However, these options are generally ineffective for porous surfaces like wood, drywall, or carpet, where moisture is retained and mould can thrive below the surface.

To eradicate mould completely, it is essential to address mould and the underlying cause, usually moisture and poor ventilation. This often means removal of contaminated materials. In cases of severe mould growth, employing a building biologist who can identify areas of mould and ascertain why there is mould growth is recommended.

What is mould illness?

Mould illness refers to a collection of symptoms that can develop following exposure to mould and mycotoxins. Presentations vary between individuals and are often non-specific, making diagnosis challenging.

Reported symptoms may include:

• Headaches and brain fog
• Fatigue and poor concentration
• Muscle or joint pain
• Mood changes or emotional disturbance
• Respiratory issues or allergic-type responses
• Inflammation and fibromyalgia-like symptoms

While research into mould-related illness is still evolving, studies have shown that mycotoxins can trigger hypersensitive reactions, contribute to immune dysregulation, and exacerbate pre-existing immune conditions, even in individuals without known immune compromise.

What to do if you suspect you have mould illness

If you have or suspect you have mould illness, both your health and your environmental exposure need to be addressed.

Environmental considerations:

• Dry up any spills or wetness immediately
• Open windows and ventilate areas frequently, especially areas where water is used such as bathrooms and laundry
• Use a HEPA filter and / or a dehumidifier
• Keep windows closed during rainy or humid weather
• Consult a building biologist for professional assessment and remediation

Health support:

• Identify and record any potential symptoms to report to your healthcare practitioner
• Consume a wide range vegetables and fruits to support antioxidant status
• Consume protein with every meal to ensure adequate detoxification and energy levels
• Seek support from a practitioner experienced in mould-related illness and environmental health

Mould exposure can be subtle, persistent, and difficult to identify, but with the right support and strategies, both your home environment and your health can be brought back into balance.

If you suspect mould exposure may be affecting your health, it’s important to address both your environmental and health-related factors. Consider investigating mould as a possible contributor and reach out for professional support.
