The Hidden Dangers of Poor Ventilation: Protecting Your Health from Damp and Mould

Everyday life generates moisture—cooking, showering, even breathing indoors adds water vapour to the air. In a well-ventilated home, this moist air is quickly removed. But in homes with poor ventilation, moisture lingers, seeps into walls and ceilings, and provides the perfect environment for mould and dust mites to thrive.

1. Breathing Problems and Respiratory Illness

The World Health Organization warns that exposure to indoor damp and mould significantly increases the risk of developing and worsening respiratory problems. This includes:

• Persistent coughing, wheezing, and breathlessness
• Triggering or worsening asthma (especially in children)
• Higher rates of bronchitis and other lung infections
• Sinus congestion and runny noses

For those already living with conditions like asthma, COPD, or allergies, mould is a powerful trigger, often leading to more frequent and severe attacks.

2. Allergic Reactions

Mould releases spores and irritants into the air. Even a mild mould problem can cause:

• Sneezing and runny or blocked noses
• Itchy or watery eyes
• Skin rashes
• Sore throats and headaches

These symptoms can affect anyone, but are especially pronounced in young children, the elderly, and those with weakened immune systems.

3. Long-term and Serious Consequences

Long-term exposure to mould has been linked to:

• The development of asthma in children who previously had no symptoms
• Chronic sinusitis and persistent upper respiratory irritation
• Worsening of underlying heart and lung conditions
• Increased risk of lung infections and, in very rare cases, life-threatening complications

The tragic case of Awaab Ishak—whose death led to the recent introduction of Awaab's Law—shows the very real dangers that can result from unchecked mould in the home.

• Children (infants and toddlers in particular)
• Pregnant women
• Elderly people
• Individuals with chronic lung diseases (asthma, COPD)
• Anyone with a weakened or suppressed immune system

Professional ventilation systems, such as MVHR, PIV, and MEV, are the most effective, long-term way to prevent mould and protect your health. Here's why:

• They continuously remove moist, stale air and replace it with clean, filtered air.
• Proper airflow keeps humidity low, making it difficult for mould to grow.
• State-of-the-art systems like MVHR help you achieve energy efficiency and healthy air quality in every room.
• Documented, maintained systems are your best proof of diligence under new regulations like Awaab's Law.

Don't wait for health issues or compliance deadlines to act. With the new legal landscape and the proven dangers of mould, investing in high-quality ventilation is an investment in your health, your property, and your peace of mind.
