Few people stop to consider what happens to the moisture in towels, clothes or other damp objects (pets) that are dried inside the house.
Many people dry clothes indoors during the winter, on the radiators, in front of the fire or just on racks. But drying clothes indoors increases the amount of moisture in the air by 30 percent or more. This creates ideal conditions for the growth of fungi, especially fungus Aspergillus fumigatus, which can easily be breathed in and thus introduced into the body.
When a damp towel is placed on a heated towel rail or even just spread out somewhere to dry, the moisture in that towel passes into the air. If the air in the house is warm it can hold a lot of moisture. The humidity in a house can be quite high – just like being in the tropics. Because the moisture in the warm air is invisible no-one wonders what happened to it.
As the air moves around in the home, it will arrive at cooler places and condense. If it hits a really cold surface like a window it becomes obvious as visible moisture. If it condenses into furnishings, carpets, drapes and other absorbent materials, it is unlikely to remain unnoticed until they become mouldy.
Drying laundry inside a home – on a rack or in a dryer that is not externally vented, is one of the greatest ways of increasing dampness in a home.
Obviously, people, pets, clothing etc that enters the home during wet weather needs to be dried. Just putting them in a warm place does not remove the moisture from the home. The only way to do that is by adequate ventilation. This can be as simple as opening the windows on a nice day. However, modern living makes open windows a rarity. The best solution is to install a home ventilation system.
