Editor's note: When I was a child, all the bedding in my home would be marked "Dust Mite Prevention". I remember this because I haven't slept in a "dust mite-proof" quilt since I moved out. Since then, I have been itchy all over and my allergies have never been better. (Simply making excuses for not loving cleanliness)

Use science to save the mess, will you wash it? The topic takes you through the historical special exhibition of the National Natural Science Museum-"Special Exhibition of Mites and Ticks" to analyze the harm caused by dust mites.

Dust mites are the main source of people's allergies in Taiwan Province Province, China, and they are the allergic killers that people talk about. Dust mites originally refer to the mites of the family Pyridae, but in recent years they generally refer to a group of mites that can cause human allergies at home. The most important mites that cause human allergy in the world are European house dust mites, American house dust mites and dermatophytes, and some non-house dust mites.

How terrible is the dust mite? About one third of people in Taiwan Province Province of China suffer from allergic diseases, and 92% of allergens come from dust mites, which are one of the terrible dust mites. The following data can show you another terrible thing about dust mites. The most suitable growth environment for dust mites is 75% ~ 80% humidity and 25℃, and the number of dust mites can increase by 17 times within 10 week. A double bed, dust mites may be as many as 2 million; A female adult mite can lay 25~50 eggs at a time, and the eggs can develop into mites within three weeks; Dust mites can produce 200 times the weight of feces in their life span of three to four months, accounting for almost110 of the bed weight.

Let people talk about the allergic killer-dust mites. Wikipedia read the above statement, I think you still want to know, what is allergic dust? How to cause allergies and how to prevent dust mites? These three points will be further explained below.

What is a genetic disease? Allergy medicine defines it as a hereditary disease. Basically, it is an allergic inflammation related to polygene inheritance. There are two kinds of chromosome abnormalities, one is closely related to the formation of asthma constitution, and the other is related to ectopic constitution. This inflammatory reaction will be stimulated by various inducing factors, leading to clinical allergic attacks. The location of the attack is related to the genetic abnormality of individual organs. For example, if a patient with long-term asthma is transferred to a healthy lung, there will be no more asthma attacks.

This inflammatory reaction is called asthma when it occurs in bronchus, allergic rhinoconjunctivitis when it occurs in nasal cavity and conjunctiva, atopic dermatitis when it occurs in skin, and allergic gastroenteritis when it occurs in gastrointestinal tract. Generally, the first three are more common.

Allergy caused by sensitive mites occurs in nasal cavity and conjunctiva, which is called allergic rhinoconjunctivitis. The so-called allergic constitution of Pexels is a state in which the human immune system overreacts to foreign substances (and most of these so-called foreign substances contain protein components, called allergens, which will trigger an immune response). Under normal circumstances, the body's immune system will have an inflammatory reaction to foreign invaders and destroy them by using white blood cells and some chemicals. Generally speaking, this inflammatory reaction will not harm the normal tissues of the body, but for people with allergies, due to the genetic abnormality mentioned above, the immune system will mistake the normal tissues for foreign bodies, or the inflammatory reaction will not stop and the body will not stop after the foreign bodies are destroyed. And allergic constitution or allergic diseases basically refer to the above four diseases.

Usually, the factors that induce allergic physical attacks can be divided into direct factors and indirect factors. Direct factors refer to respiratory virus infection, allergens (dust mites, dust, feathers, mold, pollen, food, etc. ) and chemicals (cigarettes, paints, etc. ); Indirect factors include strenuous exercise, drinking ice water, drastic weather changes and emotional instability.

Bird hair is also one of the allergens. Why Pixabay with the development of human economy and medicine, more and more people get allergic diseases? Even more people died of allergic diseases? Of course, this is directly related to the deterioration of our living environment. In addition, due to the dense, closed houses and difficult ventilation, the concentration of allergens gradually accumulates and remains high, making people with allergic constitution prone to allergic diseases.

Dust mites can cause allergies, all caused by excrement. Dust mite is a small arthropod, invisible to the naked eye, with a size of about 0.25~0.33 mm. It mainly feeds on water droplets, fungi, molds, bacteria, pollen and insect carcasses on human skin. And these substances are often contained in the dust at home. So dust mites like to live in closed houses. Dust mites and their excreta and secretions are the main substances that cause human allergies. If inhaled through the respiratory tract, it will cause allergic symptoms. Each dust mite can produce about 20 excreta every day, which will continue to cause allergic reactions. Even after the death of dust mites, their bodies will still cause allergic reactions in humans. This is because dust mites contain protein components that cause allergic reactions in humans.

In Taiwan Province Province, China, the number of dust mites in mattresses is the largest, and about 66% ~ 100% of household mattresses are found to have dust mites, followed by quilts and pillows.

Dust mites were found in about 66% ~ 100% of residential mattresses, followed by quilts and pillows. Pexels will clean up dust mites in the new year, and then mattresses, pillows, quilts, sofas, carpets and curtain cloth at home are all hiding places for dust mites. To keep people allergic to dust mites away from threats, it is best to have a ventilated environment and take appropriate anti-mite measures to minimize the degree of allergy. Dust mites can be controlled in the following ways:
