Taking an antihistamine medicine about an hour before entering a pet-inhabited home can also assist reduce your symptoms.

The Allergy UK website has more information about domestic pet allergies.


Preventing severe allergies (anaphylaxis)

If you’re at risk of experiencing a severe allergic reaction (anaphylaxis), make certain you carry 2 adrenaline auto-injectors with you everywhere.

What else gets into dust that might cause allergies?

The dust in your home may contain pet hair and dander, mold or pollen spores, and dust mite or cockroach body parts and droppings, every of which are common allergens.

These allergens can cause an allergic reaction when you inhale or come into contact with them.

An allergen is a substance that causes an allergic reaction. Both the body parts and the waste of dust mites are allergens for numerous people. Most dust mites die in low humidity levels or extreme temperatures. But they leave their dead bodies and waste behind. These can continue to cause allergic reactions.

In a warm, humid home, dust mites can survive every year.

Who Gets Allergies?

The tendency to develop allergies is often hereditary, which means it can be passed below through genes from parents to their kids. But just because you, your partner, or one of your children might own allergies doesn’t mean that every of your kids will definitely get them. And someone generally doesn’t inherit a particular allergy, just the likelihood of having allergies.

Some kids own allergies even if no family member is allergic, and those who are allergic to one thing are likely to be allergic to others.

What Things Cause Allergies?

Airborne Allergy Symptoms

Airborne allergens can cause something known as allergic rhinitis, which generally develops by 10 years of age, reaches its peak in the teens or early twenties, and often disappears between the ages of 40 and 60.

Symptoms can include:

  1. stuffy nose
  2. sneezing
  3. itchy nose and/or throat
  4. coughing

When symptoms also include itchy, watery, and/or red eyes, this is called allergic conjunctivitis.

(Dark circles that sometimes show up around the eyes are called allergic «shiners.»)

Common Food Allergens

Up to 2 million, or 8%, of kids in the United States are affected by food allergies. Eight foods account for most of those: cow’s milk, eggs, fish and shellfish, peanuts and tree nuts, soy, and wheat.

  1. Soy. Soy allergy is more common among babies than older kids. Numerous infants who are allergic to cow’s milk are also allergic to the protein in soy formulas. Soy proteins are often a hidden ingredient in prepared foods.
  2. Cow’s milk(or cow’s milk protein). Between 2% and 3% of children younger than 3 years ancient are allergic to the proteins found in cow’s milk and cow’s milk-based formulas.

    Most formulas are cow’s milk-based. Milk proteins also can be a hidden ingredient in prepared foods. Numerous kids outgrow milk allergies.

  3. Peanuts and tree nuts. Peanut allergies are on the rise, and as are allergies to tree nuts, such as almonds, walnuts, pecans, hazelnuts, and cashews. Most people do not outgrow peanut or tree nut allergies.
  4. Eggs. Egg allergy can be a challenge for parents. Eggs are used in numerous of the foods kids eat — and in numerous cases they’re «hidden» ingredients.

    What causes allergies in bedroom

    Kids tend to outgrow egg allergies as they get older.

  5. Fish and shellfish. These allergies are some of the more common adult food allergies and ones that people generally don’t outgrow. Fish and shellfish are from diverse families of food, so having an allergy to one does not necessarily mean someone will be allergicto the other.
  6. Wheat. Wheat proteins are found in numerous foods, and some are more obvious than others. Although wheat allergy is often confused with celiac disease, there is a difference.

    Celiac disease is a sensitivity to gluten (found in wheat, rye, and barley). But a wheat allergy can do more than make a person feel ill — love other food allergies, it also can cause a life-threatening reaction.

Airborne Allergies

To assist kids avoid airborne allergens:

  1. If your kid has a pollen allergy, hold the windows closed when pollen season is at its peak, own your kid take a bath or shower and change clothes after being outdoors, and don’t let him or her mow the lawn.
  2. Keep family pets out of your child’s bedroom.
  3. Use special covers to seal pillows and mattresses if your kid is allergic to dust mites.
  4. Remove carpets or rugs from your child’s room (hard floors don’t collect dust as much as carpets do).
  5. Clean when your kid is not in the room.
  6. Don’t hang heavy drapes and get rid of other items that permit dust to build up.
  7. Keep kids who areallergic to mold away fromdamp areas, such as some basements, and hold bathrooms and other mold-prone areas clean and dry.

Food, Medicines, or Insect Allergy Symptoms

  1. swelling
  2. wheezing
  3. hives
  4. coughing
  5. itchy, watery, or swollen eyes
  6. vomiting
  7. throat tightness
  8. diarrhea
  9. hoarseness
  10. stomachache
  11. trouble breathing
  12. a drop in blood pressure, causing lightheadedness or loss of consciousness

Allergic reactions can vary.

Sometimes, a person can own a mild reaction that affects only one body system, love hives on the skin. Other times, the reaction can be more serious and involve more than one part of the body. A mild reaction in the past does not mean that future reactions will be mild.

What Are the Symptoms of Dust Mite Allergy?

Common dust mite allergy symptoms include:

  1. Postnasal drip (a flow of mucus from behind your nose into your throat)
  2. Sneezing
  3. Itchy skin
  4. Runny nose
  5. Itchy nose, mouth or throat
  6. Stuffy nose
  7. Itchy, red or watery eyes

  4. Trouble sleeping caused by shortness of breath, coughing or wheezing

What are dust mites?

Dust mites are tiny creatures that frequently make their home in places love furniture, carpets, and bedding.

They are too little to be seen without a microscope or magnifying glass. They own eight legs and are not true insects, but relatives of spiders.

Dust mites feed on the flakes of skin shed by humans (and animals) every day. They prefer environments with 70 to 80% humidity, and temperatures of 68 to 77°F.

How Do Doctors Diagnose Mold Allergy?

To diagnose an allergy to mold or fungi, the doctor will take a finish medical history. If they suspect a mold allergy, the doctor often will do skin tests or allergen specific IgE blood tests.

Extracts of diverse types of fungi may be used to scratch or prick the skin. If there is no reaction, then you probably don’t own an allergy. The doctor uses the patient’s medical history, the skin testing results and the physical exam to diagnose a mold allergy.

How Can I Prevent an Allergic Reaction to Mold?

There is no cure for allergies. But you can reduce your allergy symptoms by avoiding contact with the mold spores. Several measures will help:

Reduce Your Exposure to Mold Spores Outside

  1. Limit your outdoor activities when mold counts are high.

    This will lessen the quantity of mold spores you inhale and your symptoms.

  2. Wear a dust mask when cutting grass, digging around plants, picking up leaves and disturbing other plant materials.

Reduce Your Exposure to Mold Spores Inside

  1. Lower your indoor humidity. No air cleaners will assist if excess moisture remains. If indoor humidity is above 50%, fungi will thrive. A hygrometer is a tool used to measure humidity. The goal is to hold humidity under 45%, but under 35% is better.

    If you own to use a humidifier, clean the fluid reservoir at least twice a week to prevent mold growth.

    Air conditioners and dehumidifiers can also be a source of mold.

  2. Use central air conditioning with a CERTIFIED asthma & allergy friendly® filter attachment. This can assist trap mold spores from your entire home. Freestanding air cleaners only filter air in a limited area. Avoid devices that treat air with heat, electrostatic ions or ozone.
  3. Prevent mold and mildew build up inside the home. Pay shut attention to mold in bathrooms, basements and laundry areas. Be aggressive about reducing dampness.

To Reduce Mold in Your Bathrooms:

What Are the Symptoms of a Mold Allergy?

The symptoms of mold allergy are extremely similar to the symptoms of other allergies, such as sneezing, itching, runny nose, congestion and dry, scaling skin.

  1. Outdoor molds may cause allergy symptoms in summer and drop (or year-round in some climates)
  2. Indoor molds may cause allergy symptoms year-round

Mold spores get into your nose and cause hay fever symptoms. They also can reach the lungs and trigger asthma.

A chemical released by allergy cells in the nose and or lungs causes the symptoms. Sometimes the reaction happens correct away. Sometimes a mold allergy can cause delayed symptoms, leading to nasal congestion or worsening asthma over time. Symptoms often get worse in a damp or moldy room love a basement. This may mean you own a mold allergy.

Rarely, some patients can own a more serious illness called allergic bronchopulmonary aspergillosis. In this condition, there is both an allergic and an inflammatory response to the mold. Symptoms may include severe wheezing, coughing and shortness of breath, much love asthma.

Food fungi, love mushrooms, dried fruit, or foods containing yeast, vinegar or soy sauce, generally don’t cause allergy symptoms of the nose, eyes and lungs.

It is more likely that reactions to food fungi are caused by the food’s direct effect on blood vessels. For example, fermented foods (like wine) may naturally contain a substance known as histamine. Histamine is also a chemical your allergy cells release during an allergic reaction. Foods that contain histamines can trigger allergy-like responses when you consume them.

What Is a Mold Allergy?

If you own an allergy that occurs over several seasons, you may be allergic to the spores of molds or other fungi.

Molds live everywhere. Upsetting a mold source can send the spores into the air.

Mold and mildew are fungi. They are diverse from plants or animals in how they reproduce and grow. The “seeds,” called spores, travel through the air. Some spores spread in dry, windy weather. Others spread with the fog or dew when humidity is high.

Inhaling the spores causes allergic reactions in some people. Allergic symptoms from fungus spores are most common from July to early drop. But fungi grow in numerous places, both indoors and exterior, so allergic reactions can happen year round.

Although there are numerous types of molds, only a few dozen cause allergic reactions.

What causes allergies in bedroom

Numerous molds grow on rotting logs and fallen leaves, in compost piles and on grasses and grains. Unlike pollens, molds do not die with the first killing frost. Most outdoor molds become inactive during the winter. In the spring they grow on plants killed by the freezing. Indoors, fungi grow in damp areas. They can often be found in the bathroom, kitchen or basement.

What Are the Treatments for Mold Allergy?

In some cases, there may be ways to reduce or remove mold exposure.

This may not always be possible and you may need medications.

  2. Avoid contact with mold. (See tips above)
  3. Take medications for nasal or other allergic symptoms. Antihistamines and nasal steroids are available over the counter without a prescription. If you own allergic asthma, talk to your doctor about which medicines may be best for you.

    You might also be a candidate for allergy shots. Allergy shots may assist reduce symptoms and medications. Study more about allergy treatments.

  4. A little quantity of allergen is injected just under the skin. This test stings a little but isn’t painful.

Dust Mite Allergy

If you own allergies or asthma, a tiny creature living in your home could be making large problems for you.

Although you can’t see them, you may be having an allergic reaction to them. They are dust mites and they live in numerous homes throughout the world.

Dust mites may be the most common trigger of year-round allergies and asthma. They are on every continent except Antarctica. It may not be possible to rid your home entirely of these creatures. But there are ways in which you can lessen your allergic reactions to them.

How Are Allergies Diagnosed?

Some allergies are fairly simple to identify but others are less obvious because they can be similar to other conditions.

If your kid has cold-like symptoms lasting longer than a week or two or develops a «cold» at the same time every year, talk with your doctor, who might diagnose an allergy and prescribe medicines, or may refer you to an allergist(a doctor who is an expert in the treatment of allergies) for allergy tests.

To discover the cause of an allergy, allergists generally do skin tests for the most common environmental and food allergens.

A skin test can work in one of two ways:

  • Moldsare fungi that thrive both indoors and exterior in warm, moist environments. Outdoors, molds can be found in poor drainage areas, such as in piles of rotting leaves or compost piles. Indoors, molds thrive in dark, poorly ventilated places such as bathrooms and damp basements. Molds tend to be seasonal, but some can grow year-round, especially those indoors.
  • A drop of a purified liquid form of the allergen is dropped onto the skin and the area is scratched with a little pricking device.
  • Pollen is a major cause of allergies (a pollen allergy is often calledhay fever or rose fever).

    Trees, weeds, and grasses release these tiny particles into the air to fertilize other plants. Pollen allergies are seasonal, and the type of pollen someone is allergic to determines when symptoms happen.

    Pollen counts measure how much pollen is in the air and can assist people with allergies predict how bad their symptoms might be on any given day. Pollen counts are generally higher in the morning and on warm, dry, breezy days, and lowest when it’s chilly and wet.

  • Antihistamines are available as pills, liquids or nose sprays.

    They can relieve sneezing and itching in the nose and eyes. They also reduce a runny nose and, to a lesser extent, nasal stuffiness.

  • Dust mites are microscopic insects that live every around us and feed on the millions of dead skin cells that drop off our bodies every day. They’re the main allergic component of home dust. Dust mites are present year-round in most parts of the United States and live in bedding, upholstery, and carpets.
  • Insect allergy. For most kids, being stung by an insect means swelling, redness, and itching at the site of the bite.

    But for those with insect venom allergy, an insect sting can cause more serious symptoms.

  • Decongestants are available as pills, liquids, nose sprays or drops. They assist shrink the lining of the nasal passages and relieve stuffiness. Use decongestant nose drops and sprays only for a short time. Oral decongestants can cause side effects such as sleeplessness and increased blood pressure in some people. Consider checking with your doctor before using them.
  • Pet allergens are caused by pet dander (tiny flakes of shed skin) and animal saliva.

    What causes allergies in bedroom

    When pets lick themselves, the saliva gets on their fur or feathers. As the saliva dries, protein particles become airborne and work their way into fabrics in the home. Pet urine also can cause allergies in the same way when it gets on airborne fur or skin, or when a pet pees in a spot that isn’t cleaned.

  • Leukotriene receptor antagonists block the action of significant chemical messengers (other than histamine) involved in allergic reactions.
  • Medicines. Antibiotics are the most common type of medicines that cause allergic reactions.

    Numerous other others, including over-the-counter medicines (those you can purchase without a prescription), also can cause allergic reactions.

  • A little quantity of allergen is injected just under the skin. This test stings a little but isn’t painful.
  • Chemicals. Some cosmetics or laundry detergents can make people break out in hives. Generally, this is because someone has a reaction to the chemicals in these products, though it may not always be an allergic reaction.

    Dyes, household cleaners, and pesticides used on lawns or plants also can cause allergic reactions in some people.

  • Cromolyn sodium is a nose spray that blocks the release of chemicals that cause allergy symptoms, including histamine and leukotrienes. This medicine has few side effects, but you must take it four times a day.
  • Nasal corticosteroids are a type of nose spray. They reduce swelling in your nose and block allergic reactions. They are the most effective medicine type for allergic rhinitis because they can reduce every symptoms, including nasal congestion. Nasal corticosteroids own few side effects.
  • Cockroaches are also a major household allergen, especially in inner cities.

    Exposure to cockroach-infested buildings may be a major cause of the high rates of asthma in inner-city kids.

After about 15 minutes, if a lump surrounded by a reddish area (like a mosquito bite) appears at the site, the test is positive.

Blood tests may be done instead for kids with skin conditions, those who are on certain medicines, or those who are extremely sensitive to a specific allergen.

Even if testing shows an allergy, a kid also must own symptoms to be diagnosed with an allergy.

For example, a toddler who has a positive test for dust mites and sneezes a lot while playing on the floor would be considered allergic to dust mites.

What Is the Treatment for Dust Mite Allergy?

The most significant step is to avoid dust mites as much as possible. Limiting your exposure to dust mites will reduce your symptoms. However, it’s almost impossible to completely get rid of dust mites in your environment. You may also need medicines to control symptoms.

Certain over-the-counter and prescription medicines may assist reduce dust mite allergy symptoms.

  1. Cromolyn sodium is a nose spray that blocks the release of chemicals that cause allergy symptoms, including histamine and leukotrienes.

    This medicine has few side effects, but you must take it four times a day.

  2. Antihistamines are available as pills, liquids or nose sprays.

    What causes allergies in bedroom

    They can relieve sneezing and itching in the nose and eyes. They also reduce a runny nose and, to a lesser extent, nasal stuffiness.

  3. Leukotriene receptor antagonists block the action of significant chemical messengers (other than histamine) involved in allergic reactions.
  4. Nasal corticosteroids are a type of nose spray. They reduce swelling in your nose and block allergic reactions. They are the most effective medicine type for allergic rhinitis because they can reduce every symptoms, including nasal congestion. Nasal corticosteroids own few side effects.
  5. Decongestants are available as pills, liquids, nose sprays or drops.

    They assist shrink the lining of the nasal passages and relieve stuffiness. Use decongestant nose drops and sprays only for a short time. Oral decongestants can cause side effects such as sleeplessness and increased blood pressure in some people. Consider checking with your doctor before using them.

Many people with a dust mite allergy do not get finish relief from medicines. This means they may consider immunotherapy (allergy shots). Immunotherapy is a long-term treatment that can assist prevent or reduce the severity of allergic reactions. It can reduce the course of allergic disease by changing your body’s immune response to allergens.

Allergy Shots – Subcutaneous Immunotherapy (SCIT) is an effective treatment that has been around for more than 100 years.

SCIT is a series of shots that own progressively larger amounts of allergen. An injection of the allergen goes into the fat under your skin about once a week during the initial phase of treatment. Numerous patients get finish relief of their allergies after being on SCIP for one to three years. Numerous physicians will continue SCIT for a period of five or more years. SCIT can provide long-lasting symptom relief. Numerous people experience benefits for at least several years after the shots stop.

Sublingual (under-the-tongue) immunotherapy (SLIT) is a way to treat dust mite allergies without injections.

Patients put little doses of an allergen under the tongue. This exposure improves tolerance to the dust mites and reduces symptoms. SLIT tablets that treat dust mite allergy were approved by the FDA in 2017. Talk with your allergist if you desire to study more about SLIT.

How Do Allergies Happen?

An allergy happens when the immune system& overreacts to an allergen, treating it as an invader and trying to fight it off. This causes symptoms that can range from annoying to serious or even life-threatening.

In an attempt to protect the body, the immune system makes antibodies called immunoglobulin E (IgE).

These antibodies then cause certain cells to release chemicals (including histamine) into the bloodstream to defend against the allergen «invader.»

It’s the release of these chemicals that causes allergic reactions. Reactions can affect the eyes, nose, throat, lungs, skin, and gastrointestinal tract. Future exposure to that same allergen will trigger this allergic response again.

Some allergies are seasonal and happen only at certain times of the year (like when pollen counts are high); others can happen anytime someone comes in contact with an allergen.

So, when a person with a food allergy eats that specific food or someone who’s allergic to dust mites is exposed to them, they will own an allergic reaction.

How Does a Doctor Diagnose Dust Mite Allergy?

To diagnose a dust mite allergy, your doctor may give you a physical exam and discuss your symptoms. If your doctor thinks you own a dust mite allergy, they may propose a skin or blood test. If you own symptoms year circular, you could own a dust mite allergy.

Skin Prick Test (SPT)
In prick/scratch testing, a little drop of the possible allergen is placed on your skin.

Then the nurse or doctor will lightly prick or scratch the spot with a needle through the drop. If you are allergic to the substance, you will develop redness, swelling and itching at the test site within 20 minutes.

What causes allergies in bedroom

You may also see a wheal. A wheal is a raised, circular area that looks love a hive. Generally, the larger the wheal, the more likely you are to be allergic to the allergen.

A positive SPT to a specific allergen does not necessarily mean you own an allergy. Health care providers must compare the skin test results with the time and put of your symptoms to see if they match.

Specific IgE Blood Test
Blood tests are helpful when people own a skin condition or are taking medicines that interfere with skin testing.

They may also be used in children who may not tolerate skin testing. Your doctor will take a blood sample and send it to a laboratory. The lab adds the allergen to your blood sample. Then they measure the quantity of antibodies your blood produces to attack the allergens. This test is called Specific IgE (sIgE) Blood Testing. (This was previously and commonly referred to as RAST or ImmunoCAP testing.) As with skin testing, a positive blood test to an allergen does not necessarily mean that an allergen caused yoursymptoms.

How Are Allergies Treated?

There’s no cure for allergies, but symptoms can be managed.

The best way to manage with them is to avoid the allergens. That means that parents must educate their kids early and often, not only about the allergy itself, but also about the reactions they can own if they consume or come into contact with the allergen.

Telling every caregivers (childcare staff, teachers, family members, parents of your child’s friends, etc.) about your child’s allergy is also important.

If avoiding environmental allergens isn’t possible or doesn’t assist, doctors might prescribe medicines, including antihistamines, eye drops, and nasal sprays.

(Many of these also are available without a prescription.)

In some cases, doctors recommend allergy shots(immunotherapy) to assist desensitize a person to an allergen. But allergy shots are only helpful for allergens such as dust, mold, pollens, animals, and insect stings. They’re not used for food allergies.

Other Common Allergens

  1. Medicines. Antibiotics are the most common type of medicines that cause allergic reactions. Numerous other others, including over-the-counter medicines (those you can purchase without a prescription), also can cause allergic reactions.
  2. Insect allergy. For most kids, being stung by an insect means swelling, redness, and itching at the site of the bite.

    But for those with insect venom allergy, an insect sting can cause more serious symptoms.

  3. Chemicals. Some cosmetics or laundry detergents can make people break out in hives. Generally, this is because someone has a reaction to the chemicals in these products, though it may not always be an allergic reaction. Dyes, household cleaners, and pesticides used on lawns or plants also can cause allergic reactions in some people.

Some kids also own what are called cross-reactions. For example, kids who are allergic to birch pollen might own symptoms when they eat an apple because that apple is made up of a protein similar to one in the pollen.

And for reasons that aren’t clear, people with a latex allergy (found in latex gloves and some kinds of hospital equipment) are more likely to be allergic to foods likekiwi, chestnuts, avocados, and bananas.

What are the symptoms of dust mite allergy?

Some common dust mite allergy symptoms include sneezing, runny nose, irritated eyes, scratchy throat, coughing, wheezing, and shortness of breath.

These same symptoms can be caused by a variety of other allergens as well, so consult your allergist for testing.

How can I get rid of dust mites?

In most parts of the world, it’s impossible to completely eliminate dust mites from your home.

However, you can take steps to minimize your exposure to dust mite allergens by keeping your home as dust-free as possible.

Vacuuming and dusting are not enough to remove dust mites, because these creatures can live deep inside your upholstery, mattresses, carpets, etc. You can cover mattresses, pillows, and upholstered furniture with zippered dust-proof covers – the material of these covers is designed with pores that are too little for dust mites to pass through. Wash sheets, blankets and other bedding every week in boiling water (no more than 120°F) to kill dust mites. Replace carpeting with hard flooring and avoid plush rugs, fabric draperies, and anything else that cannot easily be washed regularly.

Use a dehumidifier to reduce the humidity in your home under 50%, making it a less suitable environment for dust mites.

Clean hard surfaces with a wet mop or cloth to avoid stirring dry allergens up into the air.

Use HEPA filters to trap dust mites and other allergens.

Change the filters every three months to ensure they remain effective.

What Are Allergies?

Allergies are abnormal immune system reactions to things that are typically harmless to most people. When a person is allergic to something, the immune system mistakenly believes that this substance is harming the body.

Substances that cause allergic reactions — such as some foods, dust, plant pollen, or medicines — are known as allergens.

Allergies are a major cause of illness in the United States.

Up to 50 million Americans, including millions of kids, own some type of allergy.

What causes allergies in bedroom

In fact, allergies cause about 2 million missed school days each year.

What Is a Dust Mite?

A dust mite measures only about one-quarter to one-third of a millimeter. They are too little to see with your eyes alone. Under a microscope, they glance love white bugs. They own eight legs, so they are not insects, but arthropods, love spiders.

Dust mites thrive in temperatures of 68 to 77 degrees Fahrenheit (20 to 25 degrees Celsius).

They also love humidity levels of 70 to 80 percent. There are at least 13 species of mites. They are every well adapted to the environment inside your home. They feed mainly on the tiny flakes of human skin that people shed each day. These flakes work their way deep into the inner layers of furniture, carpets, bedding and even stuffed toys. These are the places where mites thrive. An average adult person may shed up to 1.5 grams of skin in a day. This is enough to feed one million dust mites!

What Are the Signs and Symptoms of Allergies?

The type and severity of allergy symptoms vary from allergy to allergy and person to person.

Allergies may show up as itchy eyes, sneezing, a stuffy nose, throat tightness, trouble breathing, vomiting, and even fainting or passing out.

Kids with severe allergies (such as those to food, medicine, or insect venom) can be at risk for a sudden, potentially life-threatening allergic reaction called anaphylaxis. Anaphylaxis can happen just seconds after being exposed to an allergen or not until a few hours later (if the reaction is from a food).

So doctors will desire anyone diagnosed with a life-threatening allergy to carry an epinephrine auto-injector in case of an emergency.

Epinephrine works quickly against serious allergy symptoms; for example, it reduces swelling and raises low blood pressure.

Common Airborne Allergens

Some of the most common things people are allergic to are airborne (carried through the air):

  1. Pet allergens are caused by pet dander (tiny flakes of shed skin) and animal saliva. When pets lick themselves, the saliva gets on their fur or feathers. As the saliva dries, protein particles become airborne and work their way into fabrics in the home.

    Pet urine also can cause allergies in the same way when it gets on airborne fur or skin, or when a pet pees in a spot that isn’t cleaned.

  2. Dust mites are microscopic insects that live every around us and feed on the millions of dead skin cells that drop off our bodies every day. They’re the main allergic component of home dust. Dust mites are present year-round in most parts of the United States and live in bedding, upholstery, and carpets.
  3. Moldsare fungi that thrive both indoors and exterior in warm, moist environments.

    Outdoors, molds can be found in poor drainage areas, such as in piles of rotting leaves or compost piles. Indoors, molds thrive in dark, poorly ventilated places such as bathrooms and damp basements. Molds tend to be seasonal, but some can grow year-round, especially those indoors.

  4. Pollen is a major cause of allergies (a pollen allergy is often calledhay fever or rose fever). Trees, weeds, and grasses release these tiny particles into the air to fertilize other plants. Pollen allergies are seasonal, and the type of pollen someone is allergic to determines when symptoms happen.

    Pollen counts measure how much pollen is in the air and can assist people with allergies predict how bad their symptoms might be on any given day.

    Pollen counts are generally higher in the morning and on warm, dry, breezy days, and lowest when it’s chilly and wet.

  5. Cockroaches are also a major household allergen, especially in inner cities. Exposure to cockroach-infested buildings may be a major cause of the high rates of asthma in inner-city kids.

Food Allergies

Kids with food allergies must completely avoid products made with their allergens. This can be tough as allergens are found in numerous unexpected foods and products.

Always read labels to see if a packaged food contains your child’s allergen.

Manufacturers of foods sold in the United States must state in understandable language whether foods contain any of the top eight most common allergens. This label requirement makes things a little easier. But it’s significant to remember that «safe» foods could become unsafe if food companies change ingredients, processes, or production locations.

Cross-contamination means that the allergen is not one of the ingredients in a product, but might own come into contact with it during production or packaging. Companies are not required to label for cross-contamination risk, though some voluntarily do so. You may see statements such as «May contain…,» «Processed in a facility that also processes…,» or «Manufactured on equipment also used for ….»

Because products without such statements also might be cross-contaminated and the company did not label for it, it’s always best to contact the company to see if the product could contain your child’s allergen.

Glance for this information on the company’s website or email a company representative.

Cross-contamination also can happen at home or in restaurants when kitchen surfaces or utensils are used for diverse foods.

After about 15 minutes, if a lump surrounded by a reddish area (like a mosquito bite) appears at the site, the test is positive.

Blood tests may be done instead for kids with skin conditions, those who are on certain medicines, or those who are extremely sensitive to a specific allergen.

Even if testing shows an allergy, a kid also must own symptoms to be diagnosed with an allergy. For example, a toddler who has a positive test for dust mites and sneezes a lot while playing on the floor would be considered allergic to dust mites.

What Is the Treatment for Dust Mite Allergy?

The most significant step is to avoid dust mites as much as possible.

Limiting your exposure to dust mites will reduce your symptoms. However, it’s almost impossible to completely get rid of dust mites in your environment. You may also need medicines to control symptoms.

Certain over-the-counter and prescription medicines may assist reduce dust mite allergy symptoms.

  1. Cromolyn sodium is a nose spray that blocks the release of chemicals that cause allergy symptoms, including histamine and leukotrienes. This medicine has few side effects, but you must take it four times a day.
  2. Antihistamines are available as pills, liquids or nose sprays. They can relieve sneezing and itching in the nose and eyes.

    They also reduce a runny nose and, to a lesser extent, nasal stuffiness.

  3. Leukotriene receptor antagonists block the action of significant chemical messengers (other than histamine) involved in allergic reactions.
  4. Nasal corticosteroids are a type of nose spray. They reduce swelling in your nose and block allergic reactions. They are the most effective medicine type for allergic rhinitis because they can reduce every symptoms, including nasal congestion. Nasal corticosteroids own few side effects.
  5. Decongestants are available as pills, liquids, nose sprays or drops. They assist shrink the lining of the nasal passages and relieve stuffiness.

    Use decongestant nose drops and sprays only for a short time. Oral decongestants can cause side effects such as sleeplessness and increased blood pressure in some people. Consider checking with your doctor before using them.

Many people with a dust mite allergy do not get finish relief from medicines. This means they may consider immunotherapy (allergy shots). Immunotherapy is a long-term treatment that can assist prevent or reduce the severity of allergic reactions. It can reduce the course of allergic disease by changing your body’s immune response to allergens.

Allergy Shots – Subcutaneous Immunotherapy (SCIT) is an effective treatment that has been around for more than 100 years.

SCIT is a series of shots that own progressively larger amounts of allergen. An injection of the allergen goes into the fat under your skin about once a week during the initial phase of treatment. Numerous patients get finish relief of their allergies after being on SCIP for one to three years. Numerous physicians will continue SCIT for a period of five or more years. SCIT can provide long-lasting symptom relief. Numerous people experience benefits for at least several years after the shots stop.

Sublingual (under-the-tongue) immunotherapy (SLIT) is a way to treat dust mite allergies without injections. Patients put little doses of an allergen under the tongue.

This exposure improves tolerance to the dust mites and reduces symptoms. SLIT tablets that treat dust mite allergy were approved by the FDA in 2017. Talk with your allergist if you desire to study more about SLIT.

How Do Allergies Happen?

An allergy happens when the immune system& overreacts to an allergen, treating it as an invader and trying to fight it off. This causes symptoms that can range from annoying to serious or even life-threatening.

In an attempt to protect the body, the immune system makes antibodies called immunoglobulin E (IgE). These antibodies then cause certain cells to release chemicals (including histamine) into the bloodstream to defend against the allergen «invader.»

It’s the release of these chemicals that causes allergic reactions.

Reactions can affect the eyes, nose, throat, lungs, skin, and gastrointestinal tract. Future exposure to that same allergen will trigger this allergic response again.

Some allergies are seasonal and happen only at certain times of the year (like when pollen counts are high); others can happen anytime someone comes in contact with an allergen. So, when a person with a food allergy eats that specific food or someone who’s allergic to dust mites is exposed to them, they will own an allergic reaction.

How Does a Doctor Diagnose Dust Mite Allergy?

To diagnose a dust mite allergy, your doctor may give you a physical exam and discuss your symptoms.

If your doctor thinks you own a dust mite allergy, they may propose a skin or blood test. If you own symptoms year circular, you could own a dust mite allergy.

Skin Prick Test (SPT)
In prick/scratch testing, a little drop of the possible allergen is placed on your skin. Then the nurse or doctor will lightly prick or scratch the spot with a needle through the drop. If you are allergic to the substance, you will develop redness, swelling and itching at the test site within 20 minutes.

You may also see a wheal. A wheal is a raised, circular area that looks love a hive. Generally, the larger the wheal, the more likely you are to be allergic to the allergen.

A positive SPT to a specific allergen does not necessarily mean you own an allergy. Health care providers must compare the skin test results with the time and put of your symptoms to see if they match.

Specific IgE Blood Test
Blood tests are helpful when people own a skin condition or are taking medicines that interfere with skin testing.

They may also be used in children who may not tolerate skin testing. Your doctor will take a blood sample and send it to a laboratory. The lab adds the allergen to your blood sample. Then they measure the quantity of antibodies your blood produces to attack the allergens. This test is called Specific IgE (sIgE) Blood Testing. (This was previously and commonly referred to as RAST or ImmunoCAP testing.) As with skin testing, a positive blood test to an allergen does not necessarily mean that an allergen caused yoursymptoms.

How Are Allergies Treated?

There’s no cure for allergies, but symptoms can be managed.

The best way to manage with them is to avoid the allergens. That means that parents must educate their kids early and often, not only about the allergy itself, but also about the reactions they can own if they consume or come into contact with the allergen.

Telling every caregivers (childcare staff, teachers, family members, parents of your child’s friends, etc.) about your child’s allergy is also important.

If avoiding environmental allergens isn’t possible or doesn’t assist, doctors might prescribe medicines, including antihistamines, eye drops, and nasal sprays. (Many of these also are available without a prescription.)

In some cases, doctors recommend allergy shots(immunotherapy) to assist desensitize a person to an allergen.

But allergy shots are only helpful for allergens such as dust, mold, pollens, animals, and insect stings. They’re not used for food allergies.

Other Common Allergens

  1. Medicines. Antibiotics are the most common type of medicines that cause allergic reactions. Numerous other others, including over-the-counter medicines (those you can purchase without a prescription), also can cause allergic reactions.
  2. Insect allergy. For most kids, being stung by an insect means swelling, redness, and itching at the site of the bite. But for those with insect venom allergy, an insect sting can cause more serious symptoms.
  3. Chemicals. Some cosmetics or laundry detergents can make people break out in hives.

    Generally, this is because someone has a reaction to the chemicals in these products, though it may not always be an allergic reaction. Dyes, household cleaners, and pesticides used on lawns or plants also can cause allergic reactions in some people.

Some kids also own what are called cross-reactions. For example, kids who are allergic to birch pollen might own symptoms when they eat an apple because that apple is made up of a protein similar to one in the pollen. And for reasons that aren’t clear, people with a latex allergy (found in latex gloves and some kinds of hospital equipment) are more likely to be allergic to foods likekiwi, chestnuts, avocados, and bananas.

What are the symptoms of dust mite allergy?

Some common dust mite allergy symptoms include sneezing, runny nose, irritated eyes, scratchy throat, coughing, wheezing, and shortness of breath.

These same symptoms can be caused by a variety of other allergens as well, so consult your allergist for testing.

How can I get rid of dust mites?

In most parts of the world, it’s impossible to completely eliminate dust mites from your home.

However, you can take steps to minimize your exposure to dust mite allergens by keeping your home as dust-free as possible.

Vacuuming and dusting are not enough to remove dust mites, because these creatures can live deep inside your upholstery, mattresses, carpets, etc. You can cover mattresses, pillows, and upholstered furniture with zippered dust-proof covers – the material of these covers is designed with pores that are too little for dust mites to pass through. Wash sheets, blankets and other bedding every week in boiling water (no more than 120°F) to kill dust mites.

Replace carpeting with hard flooring and avoid plush rugs, fabric draperies, and anything else that cannot easily be washed regularly.

Use a dehumidifier to reduce the humidity in your home under 50%, making it a less suitable environment for dust mites.

Clean hard surfaces with a wet mop or cloth to avoid stirring dry allergens up into the air.

Use HEPA filters to trap dust mites and other allergens.

Change the filters every three months to ensure they remain effective.

What Are Allergies?

Allergies are abnormal immune system reactions to things that are typically harmless to most people. When a person is allergic to something, the immune system mistakenly believes that this substance is harming the body.

Substances that cause allergic reactions — such as some foods, dust, plant pollen, or medicines — are known as allergens.

Allergies are a major cause of illness in the United States. Up to 50 million Americans, including millions of kids, own some type of allergy.

In fact, allergies cause about 2 million missed school days each year.

What Is a Dust Mite?

A dust mite measures only about one-quarter to one-third of a millimeter. They are too little to see with your eyes alone. Under a microscope, they glance love white bugs. They own eight legs, so they are not insects, but arthropods, love spiders.

Dust mites thrive in temperatures of 68 to 77 degrees Fahrenheit (20 to 25 degrees Celsius). They also love humidity levels of 70 to 80 percent. There are at least 13 species of mites.

They are every well adapted to the environment inside your home. They feed mainly on the tiny flakes of human skin that people shed each day. These flakes work their way deep into the inner layers of furniture, carpets, bedding and even stuffed toys. These are the places where mites thrive. An average adult person may shed up to 1.5 grams of skin in a day. This is enough to feed one million dust mites!

What Are the Signs and Symptoms of Allergies?

The type and severity of allergy symptoms vary from allergy to allergy and person to person.

What causes allergies in bedroom

Allergies may show up as itchy eyes, sneezing, a stuffy nose, throat tightness, trouble breathing, vomiting, and even fainting or passing out.

Kids with severe allergies (such as those to food, medicine, or insect venom) can be at risk for a sudden, potentially life-threatening allergic reaction called anaphylaxis. Anaphylaxis can happen just seconds after being exposed to an allergen or not until a few hours later (if the reaction is from a food).

So doctors will desire anyone diagnosed with a life-threatening allergy to carry an epinephrine auto-injector in case of an emergency. Epinephrine works quickly against serious allergy symptoms; for example, it reduces swelling and raises low blood pressure.

  5. Cockroaches are also a major household allergen, especially in inner cities.

    Exposure to cockroach-infested buildings may be a major cause of the high rates of asthma in inner-city kids.

Food Allergies

Kids with food allergies must completely avoid products made with their allergens. This can be tough as allergens are found in numerous unexpected foods and products.

Always read labels to see if a packaged food contains your child’s allergen. Manufacturers of foods sold in the United States must state in understandable language whether foods contain any of the top eight most common allergens.

Companies are not required to label for cross-contamination risk, though some voluntarily do so. You may see statements such as «May contain…,» «Processed in a facility that also processes…,» or «Manufactured on equipment also used for ….»

Because products without such statements also might be cross-contaminated and the company did not label for it, it’s always best to contact the company to see if the product could contain your child’s allergen.

Glance for this information on the company’s website or email a company representative.

Cross-contamination also can happen at home or in restaurants when kitchen surfaces or utensils are used for diverse foods.


House dust mites

One of the biggest causes of allergies are dust mites, which are tiny insects found in household dust.

You can limit the number of mites in your home by: 

  1. using a vacuum cleaner fitted with a HEPA (high efficiency particulate air) filter, as it can trap more dust mites than ordinary vacuum cleaners
  2. choosing wood or hard vinyl floor coverings instead of a carpet
  3. using tested allergy-proof covers on mattresses, duvets and pillows
  4. fitting roller blinds that can be easily wiped clean
  5. cleaning cushions, soft toys, curtains and upholstered furniture regularly, either by washing (at a high temperature) or vacuuming
  6. choosing leather, plastic or vinyl furniture instead of upholstered furniture
  7. regularly wiping surfaces with a damp, clean cloth – avoid dry dusting, as this can spread dust into the air

Concentrate your efforts of controlling dust mites in the areas of your home where you spend the most time, such as the bedroom and living room.

You can discover more information on allergies in the home on the Allergy UK website.


Hay fever

Pollen allergies, more commonly known as hay fever, are caused when trees and grasses release pollen into the air.

Doctors often call hay fever allergic rhinitis.

Different plants pollinate at diverse times of the year, so the months you get hay fever will depend on what sort of pollen you’re allergic to.

Typically, people are affected during spring (trees) and summer (grasses).

To help keep your hay fever under control, you can:

  1. avoid grassy areas, such as parks and fields, particularly in the early morning, evening or night, when the pollen count is highest
  2. check weather reports for the pollen count and stay indoors when it’s high, if possible
  3. shower and change your clothes after being exterior
  4. avoid drying clothes and bedding exterior when the pollen count is high
  5. keep doors and windows shut when possible
  6. wear wraparound sunglasses to protect your eyes
  7. if you own a lawn, try asking someone else to cut the grass for you 

Find out how to prevent hay fever


Insect bites and stings

If you own ever suffered a bad reaction to an insect bite or sting, it’s significant to take precautions to minimise your risk.

When you’re outdoors, particularly in the summer, you could:

  1. apply insect repellent
  2. cover exposed skin
  3. wear shoes
  4. avoid wearing strong perfumes or fragrances, as these can attract insects

Find out how to prevent insect bites and stings


Mould spores

Tiny particles released by moulds can cause an allergic reaction in some people.

You can assist prevent this by:

  1. dealing with any damp and condensation in your home
  2. keeping your home dry and well ventilated
  3. not drying clothes indoors, not storing clothes in damp cupboards, and avoiding packing clothes too tightly in wardrobes
  4. removing any indoor pot plants from your home
  5. avoiding damp buildings, damp woods and rotten leaves, cut grass and compost heaps


Food allergies

By law, food manufacturers must clearly label any foods that contain something that’s known to cause allergic reactions in some people.

By carefully checking the label for the list of ingredients, you should be capable to avoid an allergic reaction.

People with food allergies most often experience an allergic reaction while eating out at a restaurant.

You can avoid this by:

  1. letting restaurant staff know your dietary requirements, including how severe your food allergy or intolerance is
  2. not relying on the menu description alone (remember, numerous sauces or dressings could contain allergens)
  3. avoiding places where there’s a chance that diverse types of food could come into contact with each other, such as buffets or bakeries
  4. communicating clearly with the waiting staff and asking for their advice
  5. always checking what allergens are in the dish, even if you own eaten it before, as recipes and ingredients can change

Remember, simple dishes are less likely to contain «hidden» ingredients.

If you’re not certain about a dish, do not risk it.
