Dust is made of fine particles of solid matter. On Earth, it generally consists of particles in the atmosphere that come from various sources such as soil lifted by wind (an aeolian process), volcanic eruptions, and pollution. Dust in homes is composed of about 50% dead skin cells.

More than just dirt, house dust is a mix of sloughed-off skin cells, hair, clothing fibers, bacteria, dust mites, bits of dead bugs, soil particles, pollen, and microscopic specks of plastic.

Sometimes a specific percentage of dust is said to be skin, usually about 70 or 80 percent, but unless you’re a molting bird or reptile (or you work in Dr. Frankenstein’s laboratory), very little of your environment is composed of dead body parts.

Household dust is mostly made up of human skin, microscopic creatures and dead bugs. This may make your skin crawl, but doesn’t offer significant health risks for most people. If dust in the air reaches a high-enough level, it can also cause explosions – which are certainly harmful to health!

Exposure to silica dust can lead to the development of lung cancer, silicosis, kidney disease and chronic obstructive pulmonary disease. It may sound like an exaggeration, but tiny amounts of silica dust can damage your lungs permanently. It may even kill you.

Dust allergies can cause wheezing, asthma attacks, bronchial infections, dermatitis and other allergy-related problems. Dust also contains chemical particles, including pesticides and other dangerous substances found in and around your home. Exposure to these may cause long-term health problems.

Eating dirt can expose you to parasites, bacteria, and toxic heavy metals. Dirt that contains a lot of potassium could lead to high blood potassium, increasing your risk for cardiac arrhythmia or cardiac arrest.

Currently it cannot be confirmed that dust exposure causes asthma to develop, however breathing in high concentrations of dust over many years is thought to reduce lung function in the long term and contribute to disorders like chronic bronchitis and heart and lung disorders.

Household dust harbours a cocktail of toxic chemicals that have been linked to an increased risk of a range of health hazards, from cancer to problems with fertility, researchers in the US have found.

You may not think it’s a big deal when you breathe in dust, but for some people, it could bring on a lung disease called hypersensitivity pneumonitis. It’s an allergic reaction to particles in the dust, and it can cause symptoms like coughing and shortness of breath.

Dust mite allergy is an allergic reaction to tiny bugs that commonly live in house dust. Signs of dust mite allergy include those common to hay fever, such as sneezing and runny nose. Many people with dust mite allergy also experience signs of asthma, such as wheezing and difficulty breathing.

Is everyone allergic to dust? While almost everyone is irritated by exposure to large amounts of dust, only some people have a true allergic reaction to house dust. This true allergic sensitivity is just as real and just as specific as an allergy to ragweed, tree pollen or cat dander.

When you minimize your exposure to dust mites, you can expect fewer or less severe allergic reactions. However, it’s impossible to completely eliminate dust mites from your environment. You may also need medications to control symptoms.

If you are allergic, wear an N95 filter mask while dusting, sweeping or vacuuming. (It can take more than two hours for the dust to settle after a thorough cleaning—so, if possible, clean when the allergic patient is away, and avoid cleaning the bedroom of an allergic person at night.)

Symptoms of dust mite 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 lying in a bed infested with dust mites.

What is a dust mite? Dust mites can be difficult to detect due to their small size. These microscopic arthropods are estimated to be only 1/4 to 1/3 millimeters long. You can only see them under a microscope, and even then, they only look like small white spider-like creatures.

Dust mites occur naturally and can appear in nearly all homes. Humidity is the most important factor in determining whether a house has high concentrations of dust mites. Dust mites do not drink water like we do; they absorb moisture from the air. In areas with low humidity, like deserts, dust mites cannot survive.

In some mystery bite cases, insects or mites truly are the culprit. These are some that should be foremost in the minds of inspectors. Bed bugs have become increasingly common and should always be considered a possibility in mystery bite investigations. People are usually bitten at night while they are sleeping.

Occasionally people are aware of small insects flying around them, but do not actually see them biting. These bites may be from small biting midges, often called “no-see-ums”. They are also known as punkies or sand flies. No-see-ums in Arizona mostly belong to the genus Culicoides, in the family Certopogonidae.

In most cases, the bites of these mites cause an itchy skin rash, which may feature small lumps or pimples. “The skin might be very itchy or red for a few days, but then that will taper off,” Merchant says of mite bites. Ice and anti-itch creams like hydrocortisone can help control the swelling and itching.

The medical term for hives is urticaria, and it describes a condition that produces raised itchy areas on the skin. If a person notices bumps on the skin that resemble mosquito bites but has not had any exposure to mosquitos, the cause is probably acute urticaria.

Chigger bites are itchy red bumps that can look like pimples, blisters, or small hives. They are usually found around the waist, ankles, or in warm skin folds. They get bigger and itchier over several days, and often appear in groups. Chigger bites start to itch within hours of the chigger attaching to the skin.

3 Simple Ways To Get Dust Mites Out Of Your Mattress

1. Baking Soda & A Vacuum. Similar to removing urine stains from a mattress, baking soda then vacuuming proves to be a potent weapon in the fight against dust mites.
2. Lowering Your Room’s Humidity.
3. Call In A Mattress Cleaning Professional.

In addition to cleaning the carpet, the heat of the steam kills dust mites. You can buy chemicals (ascaricides) that kill dust mites and that you can use on carpeting and furniture.

Because dust mite particles often become airborne, using an air purifier with a high-efficiency particle air (HEPA) filter can also help remove these and other allergens from the air. Fortunately, an air purifier is great for dust removal, including dust mite allergens, and can help you breathe easier.

Wash them in water that is at least 130°F (54°C) to kill dust mites, and wash them regularly — preferably every week.
