A damp and humid home encourages mould growth. Mould can trigger COPD symptoms and increase the likelihood of a flare-up. To avoid mould growth, keep your home warm, dry and well-ventilated. You can reduce humidity by using a dehumidifier. Placing a dehumidifier in the bedroom may be particularly useful if your COPD symptoms worsen during the night.
