Most people think they have a slight cold when they have a runny nose or watery eyes. When this continues for some time, they will likely go to the doctor to receive medication only to find that you may have dust mite allergies. However, dust mite allergies do cause the same symptoms. These mites are present in just about ball homes in the rugs, carpeting, sofas and especially in the beds. If you have never heard of these mites, they are miniscule eight-legged insects that like to live in layers of material in warm moist environments.
The main source of food for mites is the dead skin that comes off the human body when they move about on an object - such as when you are in bed. The female of the species can live up to ten weeks and lay hundreds of eggs. Your mattress could be alive with millions of these mites and you would never know if you do not know how to recognize the symptoms of a dust mite allergy. It is not the dust mite itself that people are allergic to, but the waste they excrete and leave behind.
Some of the symptoms of an allergy to dust mites are:
* Watery eyes
* Runny nose
* Itching skin
* Nasal congestion
* Puffiness under the eyes
* Postnasal drip
* Pain and pressure in the face
For those suffering from asthma, the presence of dust mites will exasperate the symptoms of the condition. They may have increased wheezing and coughing, difficulty breathing and even ling congestion. The symptoms may be worse at night, which is because of the dust mites in the mattress and pillow. The symptoms of an allergy can be very mild so that you would not have to seek medical help. However, they can also be very severe - so much so that person may feel that he/she is dying.
What cause allergies to dust mites? When you inhale the residue of the mites, your body reacts to this foreign substance invading the body. It produces an antibody called immunoglobulin. As soon as the body comes in contact with the dust mite excretion, the body launches an attack on the invading substance. Then this antibody triggers the release of histamine, which is what cause the nasal congestion, runny nose and watery eyes because of the swelling it causes in the mucous linings in the body.
Even though some people live happily enough never knowing that they have dust mites, there are certain risk factors involved. In some cases allergic reactions to these mites is inherited so if there is someone in your family with such an allergy, you can develop one as well. You are also at risk id there is a high level of mites and younger children are more at risk than adults. When you do contact your doctor about your symptoms, you will likely have to undergo allergy testing. This will tell you whether or not the mites are the reason you are not feeling well.
