While mould is often associated with unsightly stains and unpleasant odours, its impact goes beyond cosmetic issues. Mould can pose serious health risks to you and your family, particularly if left unchecked. In this article, we'll explore why mould is dangerous, the potential health risks it presents, and the symptoms to watch out for.

 Understanding the Health Risks of Mould

  1. Respiratory issues: Mould spores can trigger respiratory problems such as coughing, wheezing, and shortness of breath, particularly in individuals with asthma or allergies.
  2. Allergic reactions: Mould can cause allergic reactions in susceptible individuals, leading to symptoms such as sneezing, runny or stuffy nose, itchy eyes, and skin irritation.
  3. Asthma exacerbation: Exposure to mould can worsen asthma symptoms and increase the frequency and severity of asthma attacks, especially in children and adults with pre-existing asthma.
  4. Irritation of mucous membranes: Mould exposure can irritate the eyes, nose, throat, and skin, leading to discomfort and inflammation in affected individuals.
  5. Fungal infections: In some cases, mould exposure can lead to fungal infections, particularly in individuals with weakened immune systems or underlying health conditions.

Symptoms to Watch Out For

  • Persistent coughing or wheezing
  • Nasal congestion or sinus problems
  • Sore throat or irritated throat
  • Itchy, watery eyes
  • Skin rash or irritation
  • Fatigue or headaches
  • Difficulty concentrating or memory problems.
  • Persistent flu-like symptoms

It's important to note that symptoms of mould-related health issues can vary depending on the individual and the extent of mould exposure. Some people may be more sensitive to mould than others and may experience more severe symptoms.


Mould is not just a cosmetic nuisance; it can have serious implications for your health and well-being. By understanding the health risks associated with mould exposure and being vigilant for symptoms, you can take steps to protect yourself and your family. If you suspect mould is present in your home, it's important to address the issue promptly and seek professional help if necessary.
