Washing dried indoors can pose a serious health threat for people with weakened immune systems or severe asthma, doctors have warned
Research shows clothes draped on drying frames or radiators can raise moisture levels in the home by up to 30 per cent, creating ideal breeding conditions for mould spores.
Experts are particularly concerned about aspergillus fumigatus spores, which can cause lung infections.
Craig Mather, a father of three from Bolton, contracted TB in 1997. The disease left his lungs weak and aggravated problems caused by childhood asthma.
Craig, 43, said: “I only started to recover when my consultant diagnosed chronic pulmonary aspergillosis and prescribed me special drugs to fight the fungal infection.
However, I noticed coughing fits and night sweats when I had washing drying on the warm bedroom radiator.”
Professor David Denning at the National Aspergillosis Centre in Manchester issued the warning after treating a growing number of patients.
He said: “My advice would be dry washing outside, in a tumble dryer or in a well-ventilated indoor space away from bedrooms and living areas to be safe rather than sorry.”
