Say Goodbye to Your Sneezing: Top Tips to Prevent Dust Mite Allergy

Learn how to avoid becoming a dust mite allergy sufferer with these tips.

You cleaned the house. All surfaces are cleaned. No dust is seen anywhere. But you still have a congested nose, swollen eyes and a runny nose when you get up in the morning, before you've even had your first cup of tea.

If that sound familiar, then chances are the dust that is visible is not the issue. These are dust mites that you can't.

Dust mites are minute, microscopic organisms that live in dust. Dust mites are tiny, microscopic creatures that reside in dust.

Dust mites are tiny insects that are related to ticks and spiders. They are often invisible to the naked eye, and that's exactly why it's so easy to miss them and hard to get rid of. They are found in bedding, carpets, upholstery, curtains and stuffed toys. They live in warm, humid conditions, and can be found in places where humans spend a lot of time, as this is where they eat shed human skin cells.

Most patients are surprised to learn that it's not the mites themselves that cause an allergy to dust mites. It's the proteins found in their excretions and in their castings. These particles float freely in the air, fall on your nasal passages on inhalation, and activate your immune system which causes all the symptoms you want to avoid.

The following symptoms are typically associated with dust mites. Here are some of the signs of dust mite allergy you should look out for.

Part of the reason dust mite allergy is not always diagnosed for a long time is the fact that the allergic reaction symptoms are very similar to other nasal allergies. The most frequently seen are:

Recurrent sneezing, especially in the morning or after waking up from sleep

• Runny or blocked nose that is not improving
• Itchy, watery eyes
Postnasal drip and dry, irritating cough
• Itchy skin
• Tightness of the chest, wheezing and shortness of breath in those with asthma as well.

Symptoms usually occur at the night time. Dust mite allergy usually occurs at night, in the early morning. It is impossible to get rid of dust mites altogether in a house. However, a significant reduction in their numbers and your exposure to their allergens can make a huge difference to symptoms and that difference can be long-lasting. These are the measures that have the most impact.

Cover Your Bedding

Dust mites tend to be in the highest densities in the bed. It's where you spend about a third of your life, and where you are exposed most of the time. Allergen-proof, zippered mattress and pillow covers protect the mites inside the mattress from the air you breathe and provide a physical barrier between the mites and the air. This is one of the most effective measures to take for dust mite allergy prevention and should be the first change that any person make.

Change bedding weekly in hot water.

Dust mites are killed by washing bedding at 130°F (54°C) or above. If cooler than that, then the mites live through the wash. The goal is to wash daily clothing weekly.The goal is to wash daily clothing weekly – the mites will build up in between if it is not washed monthly. Duvets or pillows that cannot be washed at this temperature can also be put in a freezer for 24 hours which will kill mites, but won't remove the allergen particles already present.

Control Indoor Humidity

Dust mites need moisture to survive. They don't ingest water, but absorb it from the air. Humidities of less than 50% in the home make it truly uninhabitable for them. This can be measured using a basic hygrometer (available at most hardware stores, lower than ₹500). Mites can be reduced quite a bit in Delhi if you run a dehumidifier or if you open windows and doors well to allow good air flow.

Rethink Your Flooring

Carpet is the perfect place for dust mites: it is warm, has a texture that dust mites like, is constantly shedding skin cells, and it is hard to clean thoroughly. Damp mopping is much easier to maintain allergen-free on hard floor (tile, wood, stone). If it is impossible to carpet removal right now, vacuum every other week with a vacuum that has a HEPA filter. Regular vacuum cleaners are likely to only stir up allergens, and can blow them back into the air.

Reduce Fabric Clutter

Over time dust mite allergens can build up on heavy curtains, upholstered sofas, stuffed toys and fabric wall hangings. It's not a matter of "clearing the room," but by being selective it helps. Use washable cotton drapes or roller blinds. Remove toys from the bed and wash them on a regular basis. In high-use areas select furniture that has smooth surfaces that can be wiped down.

Dusting done properly.

Dry dusting releases allergen dust particles into the air, allowing them to remain airborne long enough to be inhaled. A damp cloth or microfiber cloth will capture the particles, rather than redistribute them. Dust before vacuuming, rather than after; and if you are aware that your dust mite allergy is severe, wear a dust mite mask when vacuuming.

When prevention is not enough, dust mite allergy treatment becomes necessary. When prevention is not enough, there is dust mite allergy treatment.

Environmental changes will decrease exposure but may not completely control symptoms, especially if the allergy has been present for a long time, or if it is severe. In those instances, treatment as well as prevention is most effective.

Antihistamines help decrease sneezing, itching and watery eyes. They do work quickly and they can be bought over the counter, but they generally don't seem to work as well for nasal obstruction.

Persistent allergic rhinitis is most effectively treated with nasal corticosteroid sprays as the first-line treatment. They are used every day to help reduce inflammation in the lining of the nose and help congestion, runny nose and sneezing for 2-4 weeks. They are not antihistamines, but instead target the inflammatory process.

Although decongestants may help relieve a stuffy nose in the short term, they should not be used for more than a few days in a row without causing rebound congestion (rhinitis medicamentosa) and this phenomenon is a common occurrence in ENT clinics.

The only way to alter the immune system's response over time to dust mite allergens is through allergy immunotherapy (allergy shots or drops under the tongue). Immunotherapy is not treating symptoms, it is treating the underlying sensitivity. It takes 2 to 3 years, but it offers long-lasting relief that lasts after treatment. Allergy testing results can help your ENT physician or allergist decide if you're a good candidate for the procedure.

It is important to see an ENT specialist when needed.

People can suffer with dust mite allergy with antihistamines from a pharmacy for a number of years without getting a proper diagnosis. This should be reconsidered in the case of:

• Symptoms have persisted for three or more months and are interfering with sleep and/or functioning.
• Use of antihistamines or decongestant sprays more than half of the time
• You have had a chronic cough, frequent sinus infections or ear issues with the nasal symptoms
• One child in your family is having frequent ear infections, snoring or is chronically congested.

Skin prick testing or blood tests would be able to determine if the cause of the allergy is dust mites and the intensity or severity of the allergy. All that information determines the treatment options, and in cases where immunotherapy is suitable, can mean a genuine long-term improvement, not perpetual symptom management.

The Realistic Picture

Dust mite allergy is a very controllable condition. It will not vanish on its own and there will be no single change that will completely solve this issue. However, if a few common environmental practices are used in conjunction with appropriate medical treatment for your sensitivity, it makes a difference in how you start your morning.

The objective is not a "house mite free". The idea is to limit your exposure to levels that do not enable your immune system to regard normal air from your bedroom as a threat.
