Dust mites are microscopic creatures that can live in your bedding and carpets and feed on this skin.It does explain why dust mite-proof pillow and mattress covers are your first line of defense against dust allergies! Facts About Dust Mites Dust mites are everywhere -- anywhere there are people or animals, warm temperatures, and high humidity. They like to be indoors, where they can get plenty of food like mold spores and dead skin cells from people and pets. If you are sensitive or allergic to them, you may have:
Runny or itchy nose and sneezing Sore throat or hoarse voice Coughing and other breathing problems Skin rash and itching Worsening of your asthma Dust mites settle down in carpet, draperies, stuffed animals, and upholstered furniture. Mattresses, pillows, and soft bedding are favorite hangouts. Dust mite covers really work. One study found that some kids with asthma need less asthma medicine when they used mattress and pillow covers. Tests of their mattresses showed that dust mites colonies there dwindled. But never decrease your asthma medicine unless instructed by your doctor. You can find dust mite covers for mattresses, pillows, and box springs at mattress and allergy supply stores and in a variety of materials. Plastic or vinyl covers with zippers help seal in allergens so you don't inhale them when sleeping. Plastic or vinyl covers are easier to keep clean than covers made of natural fibers. Many plastic covers have an outer layer of material like nylon to make them more comfortable.
If possible, cover your mattress and pillows when they are new. Put duct tape or electrical tape over cover zippers to double-block dust-mites from coming and going. More Ways to Minimize Dust Mites Use a bed with a wooden or metal frame. Wash bedding in hot water. Cold water does not kill dust mites. Wash sheets and pillowcases at least once a week. Wash comforters and bedspreads every one to two months. Consider using an electric blanket, which can reduce humidity on bed surfaces. Wash and dry stuffed animals often and keep them off beds. Clean mattresses in late winter and early spring. That will kill any dust mites that survived the winter and reduce their numbers in the summer months.THE other night my husband and I were having serious pillow talk. But not the kind you might think. Ours went something like this: Husband: Don’t we need new pillows? We’ve been sleeping on ours for, like, seven years. Me: They seem fine to me.
Husband: But they are probably full of dust mites and other gross stuff. A cool $400 later, I had bought eight new down pillows — two for each member of our family. I was about to investigate dust mite protection covers (an additional $100) when I stopped myself. Really, should I care this much about dust mites? I have mild allergies and so does my husband, but I’ve never felt that my pillow was making me sick. And these fluffy new pillows and covers were expensive. Dust mites are microscopic creatures, about 0.4 millimeters in length, that feast on flakes of human skin. Their feces contains a substance called DerP1, a very potent allergen. People who are allergic to dust mites may have asthmalike symptoms, eczema or chronic sinus problems. Many of us believe that bed linens, pillows and mattresses must be replaced regularly to prevent them from becoming home to vast colonies of these nasty creatures, lest their feces spread and cause allergic reactions in family members.
According to most experts, the truth is a bit more prosaic. People who have allergies to dust mites should indeed take measures to protect themselves. But everyone else can skip the expensive trips to Linens “R” Us. The trouble is, it’s not always clear whether you have a mite allergy. And even when you know you are allergic, there’s a lot of confusion about which strategies really work. Here’s how to decide if you should be worrying about your bedding and the dust mites that take up residence in them — along with expert advice on the most effective home interventions. AN ALLERGY TEST Mites proliferate in warm, humid climates. They are almost nonexistent in places like New Mexico but thrive in tropical areas like Florida. Here’s a mite test: “If your home is full of static electricity, you likely do not have mites at the moment,” said Dr. Thomas Platts-Mills, director of the Asthma and Allergic Disease Center at the University of Virginia. But if the temperature and humidity rise, watch out.
About one in four Americans has some type of allergy, and within that group about two-thirds are allergic to dust mites, said Dr. James Sublett, an allergist in Louisville, Ky., who is chairman of the Indoor Allergen Committee of the American College of Allergy, Asthma and Immunology. “Very few people are allergic to just one thing,” he said. If you’re not sure whether you have a sensitivity to dust mites, ask yourself these questions: Do I have persistent sniffles and sinus headaches? Do I often wake up with scratchy eyes? Do I sneeze repeatedly first thing in the morning? “Sometimes symptoms are obvious, but sometimes they are subtle,” said Dr. Diego Saporta, an otolaryngologist in Elizabeth, N.J., who specializes in allergy management. “Your only symptom might be chronic nasal congestion.” If you do have bothersome symptoms, consider seeing an allergist for testing. And don’t forget the children: Dust mite allergy is common among children and a risk factor for developing asthma, said Dr. Platts-Mills.
The sooner you intervene, the less likely your child’s symptoms will escalate into something more severe. Allergy tests take about an hour and most insurers cover the expense, which can range from $500 to $1,000, depending on where you live. At the end of your visit, you will know what you are allergic to and to what degree. THE SCIENTIFIC CONTROVERSY If you are allergic to dust mites, you will need to reduce your exposure to them. But first, you should know about a scientific dispute over bedding. Most researchers endorse protective bedding as a way to reduce exposure to dust mites. But a meta-analysis of 54 studies on interventions to control dust mites, published in 2008 by the nonprofit Cochrane Collaboration, concluded, “Chemical and physical methods aimed at reducing exposure to house dust mite allergens cannot be recommended.” Dr. Peter Gotzsche, lead author of the study and director of the Nordic Cochrane Center in Copenhagen, said in an e-mail, “The reduction in exposure to mites and mite allergens that can be obtained by encasings, chemicals, vacuum cleaning, etc., is far too small to have any effect.”
Most allergists and environmental health experts disagree. The American Academy of Allergy, Asthma and Immunology and the National Heart, Lung and Blood Institute, for example, tell allergic consumers to encase mattresses, box springs and pillows in special allergen-proof fabric covers. Though the research has been mixed, a study published in the New England Journal of Medicine in 2004 found that covering children’s mattresses and pillows with special mite-proof casings helped reduce asthma complications. A similar study, published by Dutch researchers in Clinical and Experimental Allergy in 2002, found that mattress encasings helped to reduce symptoms in asthmatic patients and concluded that “their use should be recommended.” APPROPRIATE STEPS Dr. Gotzsche’s views notwithstanding, most experts recommend a variety of interventions for those allergic to dust mites. Mites multiply quickly in high humidity and can take up residence in sheets and blankets in a matter of days.
Wash your bedding (including comforters and duvet covers) weekly in hot water and use a hot dryer. It is not necessary to replace them with new linens. But if you’d rather start fresh, spring for new pillows. It doesn’t matter what kind you buy; it matters more that you protect both your pillows and your mattress with special mite-proof covers, experts say. The new covers are made of old-fashioned typewriter ribbon material, which has a tight weave that does not allow mites to penetrate but is soft to the touch. Be sure you get covers from a reputable company, like Mission Allergy or National Allergy Supply. Covers cost $15 to $40 for pillows and $100 or more for mattresses. If your allergies are severe, your doctor may also suggest that you remove carpets from your home, or at least from your bedroom, and use Venetian blinds rather than fabric drapes. Dust mites take refuge in carpets but can’t live on hard surfaces like wood floors or plastic. If you aren’t allergic to dust mites, forget the urban horror stories about tumbleweeds of mite feces blowing through your home.
