Is High Tech Underwear More Healthy?

Typical case is Ms. Hao, 58 years old, who lives in Haidian District, Beijing. Hao's son's unit welfare is good, a few days ago issued a set of all wool warmth underwear. The son was very filial and thought that his mother would not want to buy such a good underwear for himself. So he took the wool underwear and gave it to his mother. Ms. Hao touched the soft underwear, smiled and climbed to the corners of his mouth. After washing and drying, he replaced the second year old cotton underwear with a history of 2 years. Unexpectedly, wearing a new thermal underwear all morning, Ms. Hao felt itchy all over her body, and red spots appeared after scratching. Miss Hao, who was itchy, had to go to Department of dermatology in 301 Hospital near Wukesong, and was diagnosed as "allergic erythema". Well, Miss Hao is puzzled that she has not eaten seafood, peppers and other foods that are susceptible to allergies. How can she suffer from "allergic erythema"? Later, according to the Department of Dermatology doctor diagnosed by Ms. Hao, the original lady Hao belonged to allergic constitution. Underwear, such as chemical fiber and wool, easily irritated the skin, causing skin allergy, dermatitis, eczema and other symptoms. Experts analyze the warm underwear styles. At present, high tech terms such as Lycra, carbon card, heat card, Sevilla and modle are everywhere. Besides the traditional warm and beautiful functions, the warm underwear is marked with whitening, moisturizing and water replenishing, and some other thermal underwear which claims to be self heating. Warm underwear varies from person to person. When consumers choose warm underwear, they should not only be alert to exaggerated publicity, but also carefully choose warm underwear according to their skin and physical condition. Otherwise, there may be symptoms of internal heat aggravation, skin allergy, skin pruritus, and so on. They may even cause rhinitis, asthma and cardiovascular diseases. To observe the air permeability and thermal underwear, many of them are made of composite sandwich material, that is, a layer of fluffy chemical fiber or ultra-thin film is sandwiched between two layers of ordinary cotton fabric, and the heat is exchanged between the skin and the outside to keep warm. This kind of thermal underwear has poor air permeability and chemical fiber is prone to static electricity. This will aggravate the internal heat of the human body, reduce the moisture content of the skin and increase the dandruff. On the other hand, it may cause sweat to the body. The urea and salts in sweat will be attached to the body surface and underwear. If not cleaned in time, it may cause skin allergies, skin itching, and even cause dermatitis, eczema and other diseases. Patients with internal heat, easy to get angry, sweating, dry skin, and dermatologic, psoriasis, eczema and other skin diseases or skin allergies should pay special attention to their breathability when choosing warm underwear. At the same time, warm underwear should be washed frequently to eliminate germs and reduce the harm of static electricity to human body. To see formaldehyde content, thermal underwear usually contains textile auxiliaries, formaldehyde, used for dyeing and softening garments. If the formaldehyde content of clothing exceeds the standard, formaldehyde can invade the human body through skin or respiratory tract, causing respiratory tract infection, inducing allergic rhinitis, asthma and other diseases. Consumers should try to avoid warm underwear with no indication of formaldehyde when buying. In addition, the newly purchased underwear should also be washed enough to remove most of the residual formaldehyde in the fabric before wearing it. Careful wear of "infrared ray" type of thermal underwear can be used as a selling point for "far infrared body health care, which can improve the microcirculation of human body", but in fact, not all people are suitable for infrared therapy. Infrared radiation is mainly used in medicine for analgesia, improving local blood circulation, relieving muscle spasm and anti-inflammatory, etc. there are some special groups who can not contact or can not contact with infrared for a long time. They should wear caution or wear infrared thermal underwear. Patients with malignant tumors and cardiovascular dysfunction should be treated with infrared rays carefully. Therefore, they should be careful to wear infrared thermal underwear. Patients with bleeding tendency and new scarring should avoid contact with infrared rays. Therefore, infrared thermal underwear should be prohibited. The above special groups can choose to buy other types of thermal underwear to keep out the cold. Pure cotton is most suitable for the elderly and children. Nowadays, many so-called "hi tech" warm elements are only propaganda gimmicks, lacking scientific basis, and there is no guarantee of safety. Children and the elderly are physically weak and their skin is fragile, so they should be especially careful in choosing underwear materials. Although the traditional cotton thermal underwear is relatively weak in warmth retention, it may be safer for children and the elderly. The warm underwear of pure cotton texture is not only soft and close, but also has good moisture absorption and permeability, no irritation and negative effect on human skin, and can keep the skin dry and dry. The elderly and children can feel comfortable wearing it. At the same time, in order to enhance the warmth retention, individuals should wear the "layers" of clothing when they are wearing pure cotton underwear. For example, when they are not exercising, they should wear a little more outside the underwear and wear thin ones when exercising. It is very important to keep warm rate. The basic function of thermal underwear is to keep warm. Therefore, the rate of warmth retention is an important criterion for measuring the quality of thermal underwear. In principle, the higher the warmth retention rate, the better the thermal performance, while the thermal insulation rate of less than 30% can only be considered ordinary underwear, not thermal underwear. Why should we treat the thermal underwear rationally? 1.. Consumers should correctly treat and identify all kinds of advertisements on the market, compare their products performance to price ratio, and rationally choose their own thermal underwear. Don't think that the more expensive they are, the better. The basic function of warm underwear is to keep warm and comfortable, but the advertising content of some products is lack of scientific basis. Do not blindly believe in the so-called high-tech concept. First of all, "card" is not so mysterious as advertised, it is just an alias for fabric made by manufacturer. For example, "warm card" and "heat card" are acrylic fibers. "Sevic" is polyester, "Lycra" and "magic card" are fibers that are elastic and not easy to coat. Secondly, antibacterial agents can not be integrated into underwear to achieve long-term sterilization effect. They can only be attached to underwear and washed away. Third, far infrared rays keep warm. After far infrared treatment, the far-infrared emissivity of the thermal underwear is increased, and the far-infrared rays generated by the thermal underwear increase correspondingly, so as to achieve the function of keeping warm. Thermal underwear is similar to the far-infrared rays emitted by the body itself. It has a certain supporting effect on arthritis and frail chills, but it has little effect on helping sleep. How can 2. choose suitable thermal underwear? The general principles of choosing warm underwear are: soft and comfortable fabric, light weight, good elasticity and good thermal insulation performance. First, look at the fabric: the quality of the underwear inside and outside is the key to the comfort of the underwear. At present, the thermal underwear in the market can be classified according to 3 categories: high, medium and low grade. The fabrics used are 40 cotton, 32 cotton, polyester cotton (cotton content between 30% and 40%), purified fiber and so on. Among them, the inner surface layer is superior to 40 cotton products. Its softness, fineness, permeability and gloss are all good, and it will not pilling after washing. Two, listen to the voice: the old style thermal underwear is used to add a thin layer of hot-melt film (commonly known as PVC plastic film) in the thermal lining to enhance the wind resistance, but this product is prone to "rustle" when it is dressed, and its air permeability is affected. It will have "hot and dry feeling" and easy to start static electricity. The new generation of thermal underwear products replace the hot-melt film with new materials and technology, which basically overcomes these shortcomings. When you purchase, you just need to shake gently or rub gently with your hands to listen to whether there is a "rustle" sound. Three. We should rely on the hand feeling: the high-quality underwear is used in the middle insulation layer to use ultra-fine fiber (diameter less than 1.2 silk) weaving, the garment is soft and comfortable, and has good thermal insulation performance. When kneading with the hand, it feels soft and without foreign body sensation. The process of carding and compounding of intermediates is also advanced, and the surface and intermediate of garment are of strong sense of unity and better wearing performance. Four. Try to be flexible: the new generation of thermal underwear is developing to many functions, such as health care, antibacterial and so on. It pays more attention to developing new products that conform to the contemporary aesthetic concept of human body curve. One of the breakthrough is to make the thermal underwear have excellent resilience. This underwear has been added to Lycra in fabric and raw materials, and the inner liner core layer adopts high elastic polymer. Although the price is higher than that of ordinary products, it has a good feeling of close fitting and no bloated feeling, and the activities of all joints are very comfortable. We must choose brands: underwear produced by famous enterprises, from raw material selection, spinning, weaving, dyeing, compounding and sewing to factory inspection, all links and processes need to be strictly checked, so that all indexes such as thermal insulation, air permeability, antibacterial and elasticity of products meet the standards. Therefore, when consumers choose to buy thermal underwear, besides looking at the price and function, they should also pay attention to selecting products that are strong, brand excellent and reputable, so as to ensure that they have no worries after buying. How should 3. warm underwear be cleaned? First, wash the laundry powder (or gently wash the laundry soap on the underwear) and pour it into the warm water at normal temperature without using too hot water. Soak the underwear for 10 minutes. After left, gently pat and rub, gently press out the sewage. Be careful not to brush with a brush. The second step, after washing, find a big towel to dry the water, or wrap it in a laundry bag and put it into the washing machine to dehydrate, but do not force it to dry. The third step is to warm up the thermal underwear first and hang it in a cool and ventilated place. Do not expose yourself to the sun for too long. Do not put it in a damp place.
