Mattresses are the perfect environment for dust mites. Mites thrive in temperatures of more than 20°C (70°F) with a relative humidity of 60-80%. These are the conditions found almost exclusively within the mattresses you and your family sleep on every night.
Bacteria infested flakes of dry skin from you and your pets offer mites a rich source of food. Their reproductive rate is very high. Natural enemies, such as predatory mites, are extinct. Up to 2,500 mites have been counted in one gram of dust. That means there are up to two million mites in one double size mattress! Each mite excretes approximately 20 pellets a day which contain allergens in the form of protease enzymes. These can attack the protective lining of the nose, throat and lungs. Moving around in bed makes the allergens airborne and easy to inhale. This stimulates the body's immune system, triggering the symptoms of asthma and rhinitis. |
