With the tail end of the bad weather, scenes so dear to winter return: closed windows, radiators on and clothes scattered around the house like flags of domestic survival. It’s such a habitual gesture that no one really thinks about it. Throw a couple of sweaters on the radiator and off you go, problem solved. But no: right there, in that apparent normality, lies one of the most harmful habits for the home, for the environment and – what is always surprising – for our health.
The first uncomfortable truth is this: we transform the radiator into a perpetual iron, which however does not heat the room. The heat gets trapped in the wet clothes and the house stays cold. The heating system works more than necessary, consumes more and becomes tired. We hear it in the bill, but we don’t immediately understand where the surge comes from.
And then there is the other consequence, the one that is not immediately seen: humidity. A single washing machine contains almost two liters of water which evaporates in domestic environments. In a small room it’s like opening the humidity tap and forgetting it is open. The air becomes heavier, the windows fog up and the walls begin to change color. It is the perfect breeding ground for mold, which is not a simple aesthetic problem: it is organisms that we breathe. And it is precisely here that the “harmless” habit of indoor laundry stops being a domestic detail and becomes a health problem.
The alarm of the experts and Craig’s story
In recent years a group of doctors from the National Aspergillosis Center in Manchester has issued a clear warning: drying laundry at home, especially on radiators, can become a serious risk for those who suffer from asthma, for those who have low immune defenses or are being treated for serious illnesses. We are not talking about extreme scenarios: we are talking about spores that exist, live and thrive in the air of our homes when it is too humid.
The most feared is called Aspergillus fumigatus. Invisible, light, resistant: in the right conditions – constant humidity and heat – it proliferates with disarming speed. We breathe it without realizing it. Most people can manage it without difficulty, but in the body of those who are more fragile it can turn into a serious lung infection.
Craig Mather, a 43-year-old man, found this out the hard way. For years he hung out his clothes in his bedroom without imagining that that gesture could worsen the consequences of old tuberculosis and childhood asthma. His nights were a succession of coughs, sweats and shortness of breath. Doctors diagnosed him with a chronic form of aspergillosis. It was then that a simple and direct phrase changed his life: “Stop drying clothes at home.”
Craig did. And within twelve months his health improved significantly: fewer symptoms, no more heavy medications, a quality of life recovered step by step. Today she tells her story so that it does not remain confined between the pages of a medical record.
Professor David Denning, infectious disease specialist, summarizes everything in a sentence worth its weight in gold:
Better to be safe than regret it.
And it’s not about creating alarmism, but about recognizing that that daily gesture – which we make without thinking – can really change the air we breathe.
A new idea of domestic well-being
There is a thin thread that unites everything: sustainability, health and common sense. It’s not about demonizing indoor laundry, but about understanding when to avoid it. Winter brings with it the temptation of “I’ll do it first”, of “but yes, what do you want it to be”, but the truth is that it is enough to change habits to give a gift to the planet, to the house and above all to our lungs.
A well-ventilated room, a window open for a few minutes, a low-consumption tumble dryer, a balcony even in winter: these are small gestures that do not upset the routine, but prevent mold and spores from transforming our nest into a less healthy environment. And the radiator? Let’s leave him free to do his duty: keep us warm, not dry the laundry which – we know well by now – can wait for solutions that are more respectful of the air we breathe.
