Mites hibernate The bedding is often taken out to dry and pat it

As the saying goes: ten winter people, eight itchy skin.

In the winter of Changsha, even if the sun comes out at noon, morning and evening are cold, cold and dry, and many people have serious skin discomfort. At the same time, the cooling makes many citizens rummage through the boxes and cabinets to find winter quilts and autumn pants, and some directly take unsheated blankets and quilts to cover the body, resulting in endless skin problems.

The reporter learned from the dermatology department of the major hospitals in the provincial capital that the number of patients who have recently been treated for skin itching has increased significantly. Experts suggest that winter mites have not disappeared, which is also the main reason for the increase in winter skin itching patients. Why? How to deal with it?

The woman's skin was itchy, and there were mites hidden in the unburned quilt

Ms. Liu, who lives in Kaifu District, has been feeling itchy skin when she recently lies in bed, and a cluster of wind-like rashes appear on her neck, chest and legs, scratching and itching and hurting. At first, she thought it was a mosquito bite, but wiping flower lotion, wind oil essence, etc. were ineffective, so she came to the dermatology department of Hunan Provincial Hospital of Traditional Chinese Medicine (the Second Affiliated Hospital of Hunan University of Traditional Chinese Medicine).

After asking about her medical history and living habits, Li Xiaosha, deputy chief physician of the dermatology department of the hospital, told Ms. Liu that she was suffering from papular urticaria, an allergic skin disease, which was most likely caused by the bite of mites in the winter quilt. Ms. Liu wondered, wasn't it dried before the quilt was collected, and how could there be mites?

The cold and dry winter has put many creatures into a dormant period, and many people think that the winter mites must have disappeared. However, although the winter is cold and dry, many families are accustomed to turning on heating or using heating facilities in winter, the indoor temperature is higher, and some families also place humidifiers indoors to increase air humidity, which meets the temperature and humidity required for the growth and reproduction of mites, suitable for the breeding of mites.

Secondly, the dander shed by the human body provides an important food source for the growth and reproduction of mites. It is inevitable that some human dander, sweat, grease, etc. will remain in the bedding, even if it is a clean bedding, it will not be sunburned for 3 consecutive months, and many mites will breed inside. In addition, because various wood-based panels and wooden furniture contain chemicals such as formaldehyde that are harmful to the body, over time, the bedding placed in the cabinet will naturally adsorb a large amount of free formaldehyde, which is also one of the causes of skin itching.

Li Xiaosha reminded that it is best to bask in the sun before using the futon. Under the action of ultraviolet rays and air flow, it can not only kill the harmful microorganisms in the bedding, but also evaporate the free formaldehyde, but also make the fibers of the bedding stretch and fluffy, so that people can sleep comfortably and safely.

Mite removal environment: humidity less than 60% or moisture content less than 12%

"In short, anti-mites are not seasonal." Li Xiaosha said that light transmission, dryness and frequent ventilation are the best weapons to eliminate mites. In winter, in order to prevent mites in the family, we must regularly open the doors and windows to maintain ventilation and light transmission, especially when using air conditioning and heating, we must pay attention to indoor ventilation. When the atmospheric relative humidity is less than 60% or the water content is less than 12%, the powder mites cannot survive in this environmental condition.

It is important to keep your wardrobe dry. Desiccant and activated carbon can play a certain role in moisture absorption and moisture protection, suitable for closed small spaces such as drawers and wardrobes. However, after using it for a period of time, the desiccant in the moisture absorption box needs to be removed and replaced with a new one.

Regularly remove indoor dust, under the bed, under the sofa, under the wardrobe and other dark corners should be cleaned frequently to eliminate the mite living environment. You can also use a vacuum cleaner and a mite remover, and its powerful suction can suck out mites in the bed and carpet. More importantly, these machines can suck away the dust, dander and other mite breeding loads, play a role in cleaning and sanitation, eliminating mites.

In addition, hot water cleaning and frequent drying can also remove mites. Bedroom bedding is covered with fine dander that has fallen off the human body, which is the hardest hit area for dust mites. It is recommended to wash sheets, duvet covers, pillowcases, etc. with hot water at least once a month and expose them to the sun. Especially when changing seasons, bed sheets, duvet covers, etc. should not be taken out and used, but should be re-ironed and used in the sun. When drying the quilt, you can pat it more and beat out the dust, dander and mite carcasses inside.

Ten winter people eight itchy skin, how to cope

As the saying goes: ten winter people, eight itchy skin. Li Xiaosha explained that skin pruritus refers to a skin disease with no primary damage clinically, and the sensation function abnormality based on itching, the main reason is: the weather is cooler, the secretion of sebaceous glands is reduced, and the skin is prone to dryness and itching; in terms of diet, most people in Hunan like to use spicy food, hot pot, liquor, etc. to drive away the cold, and some people have dry stools, and it is difficult to eliminate toxins in the body, which aggravates the itching. In addition, if you always take a bath with alkaline soap or shower gel, it will also aggravate the itching of the skin.

In what ways does dry skin be relieved? Li Xiaosha made 4 suggestions:

Moisturizing and anti-drying. Indoor drying in winter, it is recommended to add a humidifier in the room to keep the humidity in the room at about 50%. Usually do a good job of moisturizing work, choose the right moisturizer for yourself, increase the moisture retention of the skin, and improve the peeling and itching caused by dryness.

Take a proper bath. Keeping the skin clean and preventing bacteria from entering the skin is key to preventing itching. However, in autumn and winter, the secretion of sebaceous glands slows down, and bathing every day can easily destroy the sebum layer on the surface of the skin, which in turn destroys the skin's natural protection and moisturizing function. Therefore, in the case of no high-intensity exercise sweating in autumn and winter, there is no need to take frequent baths, try to avoid scratching and hot water, it is recommended that the water temperature is 40 ° C ~ 50 ° C, the time is not more than 30 minutes, take a bath every other day, and avoid bathing with alkaline soap. It is best to apply moisturizing products to the whole body after bathing.

Eat a light diet. Eat less spicy and irritating food, autumn and winter are dry and evil, and eating too much beef and mutton will cause the fire to be added fuel. It is recommended to eat a light diet, drink more boiled water, eat more vitamin-rich foods such as fresh fruits and vegetables, and enhance your own immunity.

Reduces irritation. It is recommended to choose loose, soft, pure cotton intimate clothing, pure cotton texture of clothing is not easy to produce static electricity, to avoid further irritation of the skin, increase the itching of the skin.
