Mould is more than an unsightly nuisance. When it grows indoors, it can affect the health of everyone in the building, and some people are far more vulnerable than others. Here we look at the symptoms of mould exposure, who is most at risk, and what you can do to protect your household.
What Types of Mould Cause Health Problems?
Not every mould is equally harmful, but many common indoor varieties can affect your health. These include Alternaria, Aspergillus, Aureobasidium, Chaetomium, Cladosporium, Fusarium, Mucor, Penicillium, and Ulocladium. The effects they cause fall into three broad categories.
Allergenic Reactions
These are the most common and typically involve sneezing, a runny nose, itchy eyes, skin irritation, and worsened asthma. They mainly affect people who are already sensitive or allergic.
Pathogenic Reactions
Pathogenic moulds can cause infections, particularly in people whose immune systems are already compromised by illness or medical treatment.
Toxigenic Reactions
The most serious effects come from toxigenic moulds, which release mycotoxins. These can cause a range of symptoms throughout the body and require professional handling.
Symptoms of Mould Exposure
Common signs include persistent coughing and sneezing, a sore throat, watery or itchy eyes, headaches, skin rashes, fatigue, and difficulty breathing. Because these symptoms overlap with colds and allergies, mould exposure is often overlooked.
Long-Term Effects of Mould Exposure
Prolonged exposure can lead to chronic respiratory problems, ongoing sinus issues, and a weakened immune response. In severe cases, particularly with toxic moulds, it may contribute to more serious neurological and respiratory conditions.
Who Is Most at Risk?
Infants and children, the elderly, people with asthma or allergies, and anyone with a weakened immune system are the most vulnerable. For these groups, even limited exposure can trigger noticeable symptoms.
Can Mould Cause Asthma in Children?
Research suggests that early, ongoing exposure to mould can increase the likelihood of children developing asthma, and it can also worsen symptoms in children who already have it. Keeping a home dry and mould-free is an important protective step.
Signs of Black Mould Exposure
Black mould exposure can produce more intense symptoms, such as persistent coughing, chronic fatigue, headaches, dizziness, and breathing difficulties. If these appear alongside visible dark, slimy growth, professional testing is strongly recommended.
How Long Does It Take to Get Sick?
There is no single answer. Some people react within hours, while others may take days or longer depending on their sensitivity, the type of mould, and how much they are exposed to.
Mould Exposure Treatment
Treatment usually starts with removing the source of the mould and limiting further exposure. Medical care may involve managing allergy or respiratory symptoms, and anyone experiencing severe or persistent effects should see a doctor.
How to Keep Mould Out of Your Home
Control moisture by fixing leaks quickly, keeping humidity low, ventilating bathrooms and kitchens, and cleaning up water spills promptly. Good airflow and dryness are your best defences against mould.
