He said: “Placing furniture too close to radiators or heaters can block the warm air from circulating properly, causing both heat and moisture to become trapped behind items like sofas, beds, and wardrobes.
“This creates damp pockets that mould will thrive in, especially in rooms with poor ventilation.
“To avoid this, make sure there’s a small gap between furniture and radiators. This will help heat circulate evenly throughout the room and reduce the chance of condensation building up in hidden spots.
“If space is tight, consider using wall-mounted or slimline radiators to keep airflow optimal and minimise the risk of trapped moisture.”
A previous study conducted by the University of Manchester revealed that the increased temperatures and lower wind speeds, more common in the summer, appeared to drive increases in fungus levels.
Professor Andrew Jones, Consultant Physician and Director of the Manchester Adult Cystic Fibrosis Centre said: “This study demonstrates that Aspergillus spores in the air are more abundant during the summer months.
“Indoor counts were directly correlated to outdoor counts and were elevated in rooms that directly connected to the outdoors, via a window.
“The fungus, found in most homes and buildings, is not normally dangerous for people who are well. However, the findings could have implications for patients who are vulnerable to Aspergillus infection.”
