Mould in our homes and workplaces is more than just an eyesore – it can trigger serious health problems. Dr Wendy Christien explains how inhaling mould spores may cause coughing, wheezing, allergies, and worsen conditions such as asthma and autoimmune disorders. Prolonged exposure can lead to chronic fatigue, brain fog, skin irritation, and even long-term immune and nervous system issues. From damp bathrooms to office air vents, mould often goes unnoticed but poses a real risk. Learn how to spot the signs, understand the symptoms, and why tackling mould is essential for protecting both your health and your environment.
