Dust Mites
The protein substances in the dust mite feces produces antibodies in allergic humans when the dust is inhaled or touches the skin. These antibodies trigger the release of histamines which cause nasal congestion, swelling and irritation of the upper respiratory passages.
Dust mites are very small creatures that live indoors in warm, moist places like the insides of pillows and mattresses and even carpets. These creatures are not the kind of bugs that you can spot, being invisible to the unaided eye. Their translucent bodies further hinder their visibility. Dust mites have no eyes or antennae, just eight legs and a mouth.
They feed off of dead skin cells that are shed from humans and pets, also called dander, they make their homes in mattresses, couches, and other frequently used furniture or carpeting. One square yard of your rug can contain as many as 100,000 dust mites. Your bed may be housing as many as 2 million. The dust mite favors a warm, almost moist surrounding, which is the condition of your mattress while you are sleeping on it.
They are microscopic and can not be seen without a microscopic lens. Unless you have an allergic reaction caused by the dust mite’s waste droppings, you’d probably never know they were there.
Though dust mites are not very dangerous, those with an allergic reaction to them will often experience itching, sneezing, and watering eyes. In severe cases they can trigger asthma attacks.
Many individuals who have indoor-allergies are actually allergic to the waste from dust mites. If you notice these symptoms, you should talk to your doctor or allergist.
Typical symptoms of an allergy to dust mites includes some or all of the following:
- Hay fever
- Watering eyes
- Runny nose
- Aching and ceasing muscles
- Asthma, difficulty breathing
- Infantile eczema
A doctor can use skin and blood tests to confirm a suspected dust mite allergy.
