Seeing the picture of the mite above, do you have a chilling feeling like me? However, in fact, in a broad sense, mites exist anywhere we live, and it can be said that they are everywhere!
Recently, the weather has become a little cooler, and the current temperature is exactly 25 ° C, and it is still raining, which can be said to be very suitable for the growth of mites.
Characteristics of mites
Mites and spiders are barely brothers, belonging to a class of arthropods Phylum Arachnids tick mites, generally about 0.5 mm in size, some as small as 0.1 mm.
A big wave of dust mites gather on your quilt...
There are more than 50,000 species of mites found in the world, second only to insects, and the most closely related to the human body are mainly the following:
(1) Dust mites. Scattered in the corner dust of factories, warehouses and living rooms, it feeds on dander, Chinese medicine powder, and mold.
(2) Powder mites. It grows in cereals, dried fruits, sugars, starches, honey and Chinese herbal medicines rich in sugars and starches.
(3) Demodex mites. It parasitizes human and mammalian hair follicles, sebaceous glands and other tissues.
(4) Scabies mites. It can parasitize within the epidermis layer of the skin and is spread by rampant rodent infestation, manual production of products, or circulation of goods.
(5) Types of occasional outdoor intrusion such as chigger mites and parasitic puddle mites.
➅ Some mites on animals such as chicken skin thorn mites, cypress bird thorn mites and so on.
The demodex mites that live on each of our faces
The room has a stable environment, suitable temperature and humidity conditions, and abundant food, which is a good place for mites to breed and grow.
Don't you care, imagine...
Every day you lie on a bed like this, brushing WeChat, playing vibrato, or doing other things... Have you ever felt a tingling in your scalp.
The smell of mites after the quilt is dried?
Female mites can lay 25 to 50 eggs at a time, and if the sheets are not washed and dried in time, millions of mites may be produced within a few weeks...
80% of the mite body is water, the other 20% is basically protein, the water will only become water vapor when it is dried, and the protein will have a barbecue smell if it is "suitable for the heat", and the burnt smell is burnt.
Apparently, mites do not produce a "taste of the sun" after being exposed to the sun.
When drying the quilt, the heating effect of the sun and ultraviolet rays will break the oxygen chemical bonds in the quilt, forming ozone. The fibers from plants or animals in the quilt are heated, mixed with the smell of ozone formation, which is the "smell of the sun" we smell! Quilts disinfected with ultraviolet lamps in hospitals will produce a similar odor.
Now you know, the smell of the quilt after being dried is not the smell of the mite's corpse at all.
Is it the same as the mites in the quilt?
Almost everyone has mites on them
Traditional sampling methods in the past, using rubber strips and microscopes, only found mites on about 25% of adult faces.
However, when the DNA of mites is tested directly on the face, almost all of them have a positive result, which indicates that the mites do appear on everyone's face.
The mites on the human body are different from the mites in the quilt
Mites that parasitize human hair follicles or sebaceous glands are demodex mites that mainly depend on secretions, keratins and cellular metabolites from sebaceous glands or hair follicles, and cannot survive once they leave the parasitic environment.
Relatively more mites are self-employed dust mites, which hide in dust and clothing, and feed on powdery dander, fiber, etc.
In terms of quantity, dust mites are the absolute majority of the mite family, and the "pampered" demodex mites in the millions of hair follicles of people are only a minority
What are the hazards of mites?
Mite carcasses, secretions and excrement are all allergens, which will cause people to appear allergic dermatitis, asthma, bronchitis, nephritis, allergic rhinitis and other diseases, seriously endangering human health. The toxins released by mite bites and the proteins in the excrement can cause allergies in the human body, causing papular urticaria, and the itch is unbearable. If you grasp it with your hands, it may also cause skin ulceration.
If mites invade the eyelashes and sebaceous glands, they may cause inflammation of the eyelid margins and loose eyelashes. Mites also absorb nutrients from the skin, irritating capillaries and cellular tissues, leading to skin deterioration. Hair follicle mites scrape the root wall of the hair root, thereby absorbing the nutrients supplied to the hair root, making the root of the hair thin, the root shaking, and beginning to lose hair, causing dandruff, head itching, scalp disease, rough hair and hair loss.
Mites are also a vector that can lead to the spread of skin infections, and mites in the skin come and go in and out of the skin at any time day and night, and the mites may leave cosmetics or other contaminants. Bacteria, etc. are carried into the skin from the outside of the skin, and if the body's skin resistance is weak, it will cause skin inflammation.
Four tricks teach you to get rid of mites
In life, mites and bacteria are almost everywhere. Coupled with the change of spring and summer seasons, temperature and humidity are more conducive to their reproduction. So how to ensure a good night's sleep in a clean bed? The following methods can be learned:
No.1
Wash your bedding regularly
It is best to wash the bedding once a week. This can make the mites and bacteria that accumulate on the bed have no place to hide, and the air is safer to breathe.
When washing sheets with washing machines, it is best to use hot water, the water temperature should be controlled between 54 ° C ~ 66 ° C, cleaning for 15 to 20 minutes, after washing, it should be dried or dried in time to achieve the role of sterilization.
No.2
Cover the bedspread during the day
During the day, a dense bedspread can be covered with sheets and pillows, which can prevent bacteria and dust. When changing and washing bedspreads and sheets, you may wish to use a vacuum cleaner or a slightly damp rag to clean up the residual dander and hair on the mattress.
No.3
Indoor dust removal
Remove indoor dust once or twice a week so that dust carrying mites and other molds cannot be dispersed in the air. Dark corners such as under the bed, under the sofa, and under the wardrobe should be cleaned frequently (you can sprinkle a little water before sweeping the floor) to eliminate the small environment in which mites live.
No.4
Pattern drying quilt
◆ Put on a black plastic bag when drying the quilt. Black is more likely to absorb heat, and ordinary dust mites can die above 50 ° C. And putting on a plastic bag can also prevent the quilt from getting dusty.
◆ Choose the best time to dry the quilt: 10:00 a.m. to 3:00 p.m. In the early morning and near dusk, the humidity in the air increases, which is unable to effectively kill dust mites.
◆ After 1 hour of drying, turn the surface, and after about 2 hours, you can put away the quilt. Exposing the quilt to the sun for a long time may cause damage to the cellulose inside and reduce the warmth effect of the quilt.
◆ Do not slap the quilt hard. This will shoot the warm air out of the quilt, but it will make it less fluffy. And after the beating, it is easy to break the fibers, resulting in the quilt agglomerating. You can gently sweep the surface of the quilt with a brush or shake the quilt gently.
