Mold mould -molds moulds allergy allergic rhinitus
Exposure to mould is widespread and non-seasonal, as moulds grow everywhere; both indoors, such as on window frames and rotting food, and outdoors, with mould on rotting leaves and fungi. Moulds release thousands of microscopic spores into the atmosphere, and it is these spores that cause the allergic reaction in people. Several well-known conditions, such as Farmer's lung and Sauna Taker's lung, are caused by mould allergy. Moulds favour damp musty conditions, such as kitchens and bathrooms, window frames, under wallpaper, on the soil of houseplants, piles of rotting leaves, grass cuttings and compost heaps.
