Key points: prevent mite infection!
Dust mites like warm and humid environment. Nowadays, more and more units and families use air conditioners, which is particularly easy to breed dust mites. Dust mites mainly breed in mattresses, bedding, pillows, sofas, carpets and other bedding in the home environment. The secretions and excretions of dust mites are strong allergens. If people inhale allergens, they may have dust mite asthma. The infection rate of adult demodex is as high as 97.68%.
Demodex parasitizes in the most developed hair follicles of human sebaceous glands, which are common on forehead and face, including nose, eyes, lips, forehead, scalp, and even * * *, chest and neck. Demodex can overflow from hair follicles with sebum or automatically and spread through bedding or towels, so it is familial. It can be transmitted from children to the elderly, and childhood infection will be parasitic for life.
Mildly infected people often have no obvious symptoms, or slight itching or tingling, and the local skin is slightly raised into solid nodules with red spots, erythema and papules, which can last for several years. Most people have dermatitis, and the symptoms are very mild. If you don't pay attention, it will cause the hair follicle to expand, block the hair follicle mouth, lead to hair follicle infection, produce inflammation around it, ruin your beauty in a short time, cause red and big acne or blackhead acne, and finally lead to rosacea after repeated attacks. Clinical investigation shows that the infection rate and infection degree of demodex in patients with rosacea-like dermatitis, erythematous papular dermatitis, acne and seborrheic dermatitis are higher than those in normal people.
Sarcoptes scabies parasitize the surface layer of human and mammalian skin. The activity, eating and excretion of sarcoptes make people feel itchy, especially at night, which makes patients often scratch their skin and cause bacterial infection, resulting in abscess, folliculitis or furuncle, which is more common in fingers, wrist flexion, elbow fossa, armpit and other places. Scabies can be spread from person to person through clothes, bedding or directly, and the whole group will suffer from scabies when it is popular.
What skin problems can mites cause?
1, dandruff, itching
Mites absorb nutrients from skin cells, destroy cells, * * * skin sensory nerves, and cause itching. At the same time, the aging and damage of skin cells are accelerated, leading to an increase in dandruff.
2, color spots
Mites continue to destroy the human body, making the skin lose nutrition, and the phenomenon of recession and atrophy appears, forming spots in the future. After a long time, symptoms such as small red pimples and acne will appear.
3, the face is shiny and bacteria breed.
Mites destroy the internal environment of hair follicles and sebaceous glands, leading to hair follicle blockage, increased sebum secretion, excessive skin oil and bacterial growth.
4. Rough skin
The reproduction of mites constantly devours nutrients in tissues and reproduces. Because it parasitizes in pores, the number of pores increases, which easily leads to skin moisture loss and rough skin.
5, blackhead acne, acne
When a large number of hair follicle mites gather in a pore, it will cause folliculitis or acne, and in severe cases, it will form large nodular acne or purulent acne. In addition, the excreta of demodex can also cause pore blockage and form "blackhead" acne.
How to prevent mites in summer?
Although ultraviolet rays have bactericidal effect, they are not very effective against mites. Because the mites are mainly on the surface of the quilt, bask in the quilt will only let the mites drill into the quilt, that is, beat the quilt cover by hand, which will only make the body and excrement of the mites into powder, leaving flying dust everywhere. The temperature of sunlight is far from enough to kill mites, and it can't be killed. So how to prevent mites in summer?
1, bed sheets, pillowcases, blankets and bedspreads should be washed once a week with hot water equal to or higher than℃, which can kill mites and remove most mite allergens. Ordinary washing powder washed in water at 25℃ for at least 5 minutes can also remove most mites and cat hair allergens, but the effect of killing live mites is uncertain. If the temperature is higher than℃ for a long time, the drum dryer can kill all mites.
2. Using high-performance dehumidifiers and air conditioners indoors can reduce the relative humidity and the total number of mites, which is both practical and effective.
3. Carpets, curtains and home decorative fabrics accumulate sundries and keep them moist, providing an ideal habitat for mite breeding. Allergic people should replace their carpets with hard surfaces. Window (cloth) curtain or sunshade curtain should be replaced by venetian blinds, home improvement fabric should be replaced by vinyl or leather cushion, and furniture can be made of wood.
4. Families with dust mite allergies need to use high-performance vacuum cleaners and often change the bags of vacuum cleaners. The bag of the vacuum cleaner should be a double-layer or high-performance air filter, or the end of the central vacuum cleaner should be opened outward to avoid allergens from forming aerosols during vacuum cleaning.
5. Families allergic to dust mites can use the refrigerator to freeze plush toys and small items, such as pillows and special clothes. Freezing at-17℃ to -20℃ for at least 24 hours is an effective way to kill mites on these articles. These items can be cleaned to remove dead mites and allergens after being frozen in the refrigerator at home. Putting mattresses and pillows outdoors for 24 hours in winter is also a way to kill mites.
6. Pay attention to personal hygiene, such as taking a bath frequently and changing clothes frequently. It is found that the dust mite allergens in hair are obviously reduced after washing hair by conventional methods, so washing hair every day is a good way to control dust mite allergens.
7. Keep the room ventilated, dry, clean and dust-free, wash quilts and sheets frequently, and try not to lay carpets indoors.
Generally speaking, the temperature is high and relatively humid, which is very suitable for the growth of mites. Therefore, we should pay attention to reducing the relative humidity at ordinary times. The humidity at home should be controlled at 40-50% as far as possible, because dust mites cannot grow below 50% relative humidity, which can effectively reduce the reproduction of mites.
9. In the family, carpets, sofas and beds are the "three gathering places" for mites. The most direct isolation method is to put pillows, mattresses and bedding into the anti-mite quilt cover. It is best to wash with hot water every month, the water temperature should exceed℃, and the soaking time should be above the requirements, so as to kill dust mites.
10. Items that are not usually used or not commonly used should be put in the cupboard as much as possible. In the decoration of goods, we should give priority to simplicity. Complexity, accumulation of all kinds of things, dusty gaps between things and so on. These may be allergens and should be avoided as much as possible.
1 1. Use acaricide. Generally speaking, the three cleaning processes of basking in the sun, patting the quilt and using a common vacuum cleaner take at least 50 minutes to complete, which consumes a lot of time and manpower. However, the use of special mite-removing vacuum cleaner only needs one-third of the previous workload, and the time is shortened to one-tenth of the original, but the effect is indeed ten times that of the original.
12, design a separate vent for the bathroom, or make good use of dehumidifier, open the window when the weather is good, and keep the home dry and ventilated, which can avoid the breeding of mold and dust mites.
13, wooden furniture is not easy to accumulate dander, which can naturally reduce the living space of dust mites. If the wooden sofa is not comfortable enough, the leather sofa that won't let dander penetrate into the cushion will be better than the fabric sofa.
14. The filter screen of air conditioner often absorbs a lot of dust and becomes a gathering place for dust mites. It is recommended to fix the cleaning screen to prevent dust mites from blowing out with the air conditioner.
15. Because of the strong reproductive ability of mites, it is recommended to clean the mat once a week. When using summer sleeping mats, it is recommended to use high-temperature ironing and insolation, and clean them once a week. Many people choose to wipe with disinfectant or expose to the sun, but only one method can not completely solve the problem of mites. Even if they are exposed to the sun and slapped, mites may still escape to the cool side of the mat. Mites are afraid of high temperature, so when cleaning the mat, you can first iron the mat with an iron wet towel for 8 minutes, and then expose it to the sun.
16. Compared with bamboo mats, summer mats contain more mites, and there are also mites on the sheets. It is recommended not to use summer mats.
