Mould is often dismissed as a minor nuisance, something that can be wiped away with household cleaners. But beneath the surface, it poses serious health risks—especially when left untreated. Exposure to mould can trigger respiratory issues, allergic reactions, and long-term health complications, making it a hidden danger in many homes and workplaces.
Understanding the health effects of mould and how to prevent exposure is essential for maintaining a safe living environment.
How Mould Affects Your Health
Mould releases tiny spores into the air, which can be inhaled and cause a range of health issues. The severity of symptoms depends on factors such as the type of mould, duration of exposure, and individual sensitivity. While some people may only experience mild reactions, others—particularly children, the elderly, and those with pre-existing conditions—can suffer from more serious health problems.
Respiratory Issues
Mould spores irritate the respiratory system and can lead to:
Persistent coughing and wheezing
Shortness of breath
Sinus congestion and throat irritation
Increased risk of asthma attacks
People with asthma or chronic lung conditions are particularly vulnerable, as mould exposure can make symptoms worse or trigger severe respiratory distress.
Allergic Reactions
Mould is a common allergen, and prolonged exposure can lead to:
Sneezing and runny nose
Itchy eyes and skin rashes
Increased sensitivity to airborne allergens
Even those who have never experienced allergies before may develop sensitivities over time when living in a mould-affected environment.
Chronic Inflammatory Response Syndrome (CIRS)
Long-term mould exposure has been linked to Chronic Inflammatory Response Syndrome (CIRS), a condition where the immune system goes into overdrive, leading to widespread inflammation. Symptoms can include:
Fatigue and brain fog
Muscle pain and joint stiffness
Headaches and dizziness
Difficulty concentrating
CIRS is particularly concerning because it can persist even after the mould is removed, requiring ongoing medical treatment.
Compromised Immune System
For people with weakened immune systems—such as the elderly, young children, or those undergoing medical treatments like chemotherapy—mould exposure can increase the risk of serious infections. Some types of mould produce mycotoxins, which can suppress immune function and make the body more vulnerable to other illnesses.
Where Mould is Most Likely to Grow
Mould thrives in damp, poorly ventilated areas, often going unnoticed until the problem becomes severe. Common problem areas include:
Bathrooms – Mould can form around showers, sinks, and ceilings due to constant humidity.
Kitchens – Leaks under sinks and behind appliances create hidden moisture pockets.
Basements and crawl spaces – Poor ventilation and excess moisture make these areas ideal for mould growth.
Air conditioning systems – If not cleaned regularly, air conditioning units can spread mould spores throughout the home.
Walls and ceilings – Water damage from leaks or flooding can lead to mould inside walls and insulation.
Even small leaks or condensation buildup can create the perfect environment for mould to spread.
How to Reduce Mould Exposure
Preventing mould is key to reducing health risks. Here are some essential steps to limit mould growth in your home or workplace:
Control humidity levels – Keep indoor humidity below 50 percent with dehumidifiers or air conditioners.
Improve ventilation – Use exhaust fans in bathrooms and kitchens to reduce moisture buildup.
Fix leaks immediately – Water damage can lead to hidden mould growth behind walls and ceilings.
Clean and dry affected areas – If water spills or flooding occurs, dry the area within 24 to 48 hours to prevent mould from taking hold.
Use mould-resistant materials – In high-moisture areas, opt for mould-resistant paint, drywall, and insulation.
Regular inspections and maintenance can help catch early signs of mould before it becomes a health hazard.
