Symptoms of mould toxicity can vary depending on individual sensitivity and the type of mould present. Common symptoms include respiratory issues like coughing and wheezing, sinus congestion, sore throat, skin irritation, headaches, fatigue, and worsening of asthma symptoms. In severe cases, exposure to mould toxins can lead to neurological symptoms such as difficulty concentrating, memory problems, and mood changes. If you suspect mould toxicity, it’s essential to consult with a healthcare professional for proper evaluation and treatment.
