Most people with dust allergies are actually allergic to proteins found in the waste produced by dust mites. Approximately 20 million Americans are allergic to the little bugs. The insects may be the most common cause of year-round allergic rhinitis and asthma symptoms, particularly in children. |
Life with dust allergies -- whether they're yours or a family member's -- comes with a load of questions. For instance, might a dust allergy explain your child's never-ending cold symptoms?
House mite allergy is a hypersensitive reaction to proteins in the excretion of dust mites. The protein attacks the respiratory passages causing hay fever and asthma. It will aggravate atopic dermatitis in people who have a tendency to this problem.
The excretion of the mites contains a number of protein substances. When these are inhaled or touch the skin, the body produces antibodies. These antibodies cause the release of a chemical called histamine that leads to swelling and irritation of the upper respiratory passages - typical asthma and hay fever symptoms. The predisposition for allergy is often hereditary.
Unlike pollen, dust mites are present all year round causing constant allergy - 'perennial' allergic rhinitis. The excretion from the mites dries out and can be launched into the air when someone walks over a rug, sits down in a chair, or shakes the bed clothes, giving allergic people immediate symptoms.
Symptoms of dust mites allergy include sneezing, runny nose, itchy nose and nasal congestion. If you have asthma, dust mites can cause you to wheeze more and need more asthma medicine. You may have more asthma symptoms at night, when you are laying in a bed infested with dust mites. Cutting down the number of dust mites in the home is an important step if you or someone in your family has allergies or asthma.
House dust mites are found in all homes. They are microscopic organisms that thrive in warm and humid houses with lots of food - human skin. The mites prefer to live in beds and, because we spend about a third of the day in bed, we inhale large quantities of dust mite allergens.
Dust mites are very common and are not usually seen, but they do exist. You can sometimes see the dust in the air through sunlight, and this is often the debris that they leave behind. They can cause allergies in asthma in some people. If you ever saw one up close, they are not pleasant to look at. If you keep up on your home and vacuüm regularly and run an air filter, you can decrease these nasty little critters from invading your home.
Dust mites love warm, humid areas filled with dust. Bed pillows, mattresses, carpets and furniture are great places for them to live. Cleaning each one of these places can make a real difference in the number of dust mites in your home. Be guided of the proper cleaning of carpet in this site: carpet cleaning auckland
Vacuuming your carpets and upholstery every week can help. Vacuums with high-efficiency filters pick up more dust mites, but even standard vacuums will help. Plastic or wood furniture that doesn't have much padding can also help keep down the number of dust mites in your home. Because dust mites love warm, humid places, keep the humidity in your home low by using a dehumidifier and running your air conditioner. Special air filters can also help reduce dust mites in the air.
Use a damp cloth or rag weekly to wipe surfaces where dust can collect. This includes countertops, shelves and windowsills. If your children have allergies, make sure to buy them stuffed animals that you can put in the washing machine.
