Coughing, sneezing, and itching all over the body for no reason, regardless of season… Many people have experienced this situation, and the reason behind it cannot be ruled out that the mites are at work.
There are still many people who are not even aware that they are allergic to mites and fail to isolate the allergens in time. This may make the situation worse.
Today we will come to get to know this little devil and see how it “competes”.
first
First figure out what a mite is
Mites are tiny parasitic animals that like to live with humans. They are only 0.1 to 0.4 mm in size and are almost invisible to the naked eye. It is widely distributed in dark corners, daily necessities and food. The most common ones are dust mites, acaroid mites, demodex mites, and scabies mites.
Among them, dust mites are the most widely distributed and have the greatest impact. They are mainly active in carpets, sofas, beddings, cushions, mattresses and pillows, and feed on human sweat, secretions, and shedding dander.
As the saying goes, “If you don’t expose your quilt for three months, 6 million mites will accompany you to sleep.” This is really not alarmist. However, you don’t need to be too nervous. Except for sensitive people, you must be very careful. For most people, as long as you maintain a clean environment, dust mites are not harmful.

How do dust mites crawl onto the bed
Dust mites do not have flying wings like insects, but they are light and can float in the air by other methods and move with the airflow.
For example, the mites living in the dust of air-conditioning filters can “swing up to 90,000 miles” in a breeze, and go wherever they want to go. There are also soft toys, fluff from cats and dogs, which can also allow dust mites to take off their fur.
As long as they can migrate to places with sufficient “food” and a comfortable environment like mattresses and pillows, they can reproduce crazily and live and work in peace. After all, about 1 gram of dander is shed by a person every day, which is enough to feed 1 million dust mites.
At the same time, when the human body enters sleep, the external environment temperature and the water evaporated from the body also provide the best growth environment for dust mites. When dust mites float to the gentle town of the bed, they will gradually expand, and a female adult can lay 30-50 eggs in a month.
Studies have shown that on an ordinary double bed, there can be nearly 10,000 dust mites and their excrement in 1 gram of bed dust
then
How do dust mites harm people who are allergic
Dust mites do not bite people, but their corpses, secretions and excrement (feces) are all allergens. When these allergens touch the skin or mucous membrane of susceptible people, they will trigger corresponding allergic symptoms, such as cough, runny nose, and bronchial asthma.
In addition, the protease in dust mite excrement can also destroy the barrier function of the skin [3], prone to allergic reactions, resulting in erythema and acne.
Not only that, the daily itchy, red, and easy tearing of the eyes may be caused by dust mites and even allergic conjunctivitis.
Allergic reactions occur at all ages. The main allergens of allergic asthma and eczema in infants and young children come from dust mites . The skin desquamation caused by eczema provides food for dust mites, which increases the number of dust mites. Children’s involuntary scratching will also aggravate the condition, resulting in a vicious circle of itching and scratching.
Finally
How to “fight wits and courage” with dust mites
We must first be aware that there will be mites in places where people are there. Don’t think that you can kill them all, but if you are a susceptible person or have a higher pursuit of health in the environment, it is best to be vigilant. From the following aspects “Battle of wits and courage.”
Don’t let them have a full meal
The dander off the skin is their ration. Pay attention to personal hygiene. The bedding needs to be replaced and cleaned every two weeks. It is recommended to develop the habit of wet cleaning.
Don’t let them keep reproducing
Dust mites are more likely to reproduce in humid environments, so controlling the environmental humidity below 50% can effectively control the level of mites and their allergens. The use of high-performance moisture absorbers and air conditioners indoors is a practical and effective tool for reducing relative humidity.
Don’t let them grab the site
Under the premise of ensuring air permeability, the textile fiber gap is reduced to much smaller than the volume of the mites, preventing dust mites from entering our site and isolating them from human dander, thereby cutting off food sources, inhibiting the reproduction of mites, and promoting their death. It is often referred to as physical anti-mite.
