Heart Conditions Due to Damp and Mould

Find out more about the way in which damp and mould can impact your heart health

Damp and mould, while often dismissed as mere nuisances, can significantly impact our health in ways we might not even realise. One of the lesser-known health risks associated with these unwelcome houseguests is the potential for heart conditions to develop or worsen. In this article, we’ll delve into the connections between dampness, mould, and heart health, exploring how these seemingly harmless issues can quietly wreak havoc on your cardiovascular system. We will also explore your best options when making a housing disrepair claim.

The Unseen Culprits: Dampness and Mould

Dampness and mould thrive in environments with excess moisture. In many regions, like the UK, where damp climates are common, homes can become breeding grounds for these unwelcome guests. The growth of mould in particular is not only unsightly but can also emit mycotoxins, which can pose health hazards when inhaled or touched.

Dampness often occurs due to leaks, inadequate ventilation, or poor insulation, creating conditions that encourage mould growth. As the moisture seeps into your home, it can lead to visible mould patches on walls, ceilings, and other surfaces. But what’s not visible are the hidden mould colonies within walls, floors, and ceiling cavities, which can persist unnoticed for prolonged periods.

Can Mould Exposure Cause Heart Problems?

You may be wondering how something as seemingly unrelated as mould and dampness could be linked to heart conditions. The truth is, it’s a connection that many people are unaware of. Scientific research has uncovered several pathways through which mould exposure can affect heart health.

Inflammatory Response

Mould spores contain allergenic proteins that can trigger an inflammatory response in the body. When inhaled, these spores may lead to respiratory symptoms like coughing, sneezing, and a runny nose. But the inflammation doesn’t stop there; it can also affect your cardiovascular system. Chronic inflammation has been linked to various heart conditions, including atherosclerosis and coronary artery disease.

Respiratory Issues

Exposure to mould can result in respiratory issues such as asthma or bronchitis. When your respiratory system is compromised, your heart has to work harder to provide oxygen to your body. Over time, this added strain can contribute to heart problems, especially in individuals with preexisting conditions.

Mycotoxins and Toxins

Mould produces mycotoxins that can be harmful when inhaled or ingested. Some of these mycotoxins are cytotoxic, meaning they can damage cells, including those in your heart. While research on the direct impact of mycotoxins on heart health is ongoing, there is growing evidence to suggest a possible connection between mycotoxin exposure and heart conditions.

What Illnesses Are Caused by Mould and Damp?

Now that we’ve established the potential links between mould, dampness, and heart health, let’s explore the broader range of health issues that can be caused by these household adversaries.

Respiratory Conditions

As mentioned earlier, respiratory issues like asthma, bronchitis, and allergic rhinitis are some of the most common health problems associated with mould and dampness. For individuals with these conditions, mould exposure can exacerbate symptoms and lead to more frequent and severe attacks.


Mould spores are notorious for triggering allergies. Sneezing, itching, and watery eyes are familiar symptoms of mould allergies. Allergic reactions can strain your cardiovascular system as well, increasing the risk of heart problems, particularly in those with pre existing heart conditions.


Mould can also cause infections, especially in individuals with weakened immune systems. These infections can sometimes spread to the heart, leading to serious complications such as endocarditis, an inflammation of the heart’s inner lining.

Cognitive and Neurological Issues

Recent research has suggested that mould exposure may be linked to cognitive and neurological problems, including memory impairment and mood disorders. These issues can indirectly affect heart health by contributing to chronic stress and lifestyle factors that increase the risk of heart disease.

Unmasking the Silent Threat

While the effects of dampness and mould on heart health are not yet fully understood, the potential risks are real and underscore the importance of addressing mould and damp problems promptly. Often, these issues remain hidden until they’ve already taken a toll on our health.

To unmask the silent threat, it’s crucial to recognize the signs of mould and dampness in your home:

Musty Odours

Dampness and mould often come with a distinct musty smell. If you notice this odour in your home, it’s a sign that you may have an issue to address.

Visible Mould

Visible mould patches on walls, ceilings, or other surfaces are a clear indication of a problem. However, remember that mould can also hide in less obvious places, like behind wallpaper or within wall cavities.

Water Stains

Water stains on ceilings or walls may indicate past or current leaks. These areas are prime spots for mould growth.


Excessive condensation on windows, walls, or other surfaces can create a breeding ground for mould. It’s a sign that humidity levels are too high in your home.

Preventing Heart Conditions Due to Damp and Mould

Preventing heart conditions due to damp and mould starts with effective prevention and mitigation strategies. Here are some key steps you can take to protect your heart and overall health:

Maintain Proper Ventilation

Good ventilation is crucial for reducing indoor humidity. Ensure that your home is well-ventilated, especially in areas prone to dampness, such as bathrooms, kitchens, and basements.

Address Water Leaks

Promptly address any water leaks in your home. Fixing leaks and addressing the source of the moisture is essential to prevent mould growth.

Keep Your Home Dry

Use dehumidifiers and air conditioning to control indoor humidity levels. Keeping your home dry is a significant step in preventing mould and dampness.

Clean and Insulate

Regularly clean and maintain your home, and insulate it properly. Insulation can help prevent moisture from seeping into walls and ceilings.

Use Mould-Resistant Products

When renovating or building, consider using mould-resistant building materials and paints. These products can be effective in preventing mould growth.

Regular Inspections

Regularly inspect your home for signs of mould and dampness. Catching the problem early can prevent it from causing health issues, including heart conditions.
