Lingerie is very important to women, it is an important partner for women, but the average life span of lingerie is about one year. When lingerie is used for a long time, we need to check whether the lingerie is still suitable, and if it is not suitable, we need to replace it in time to avoid causing harm to the body. What are the dangers of old underwear? 1, let the body aging Women’s bodies are changing at any time, especially the chest, it is easy to change with the changes in the physiological period and weight gain or loss, once the weight down, the bust is also shrinking the most powerful place. In addition, with the aging of the body, the underwear bought a few years ago may not be suitable for the body now, barely wearing will only bring discomfort and even injury to the body. 2, prone to breast disease old underwear deformation, resulting in improper bra wear, easy to make breast deformation, and even breast disease. 3, body deformation With age and weight changes, the body curve will also change. When underwear is no longer suitable, if you do not pay attention to wear, it will lead to body deformation. How do you know that the underwear should be changed? 1.Find a flat place to spread the bra open. 2.If a part of the bra’s iron ring leaves the flat surface and warps up, it means that the iron ring has been distorted, such a bra should be discarded and a new bra should be purchased. 3, no matter how short the straps are adjusted will still be loose, indicating that the bra aging, a sign of deterioration. 4, whether the leather band of the panties loses elasticity, whether there are threads coming out of the various edges, whether they look decolored or not, if they are sure, then the panties need to be replaced. The five most common minefields for cleaning underwear minefield one: washing underwear in the washing machine According to a survey, 60.2% of the mold detected in the inner slot of the washing machine, where nearly 80% of the skin problems of infants and children are related to improper handling of clothing. The washing machine is an entry point between bacteria and our bodies. And underwear, as the umbrella of the breasts and private parts, if washed in such a “highly polluted” environment, I’m afraid that the more “dirty”! There is no doubt that washing underwear in the washing machine has become the biggest minefield of family cleaning underwear. Some friends may say, add a laundry bag on the good. This statement is also wrong, the role of the laundry bag is to protect clothing is not entangled, not subject to wear and tear, not deformation, etc., but it does not protect the underwear from “pollution”. minefield two: underwear “accumulate less into more” and then wash usually too busy at work, after the evening shower do not want to move, washing machine underwear is not good, so the underwear “accumulate less into more”, wait until the accumulation of a certain amount, the weekend and then a tub of water to wash clean! This is another big minefield! You know the saying “quantity leads to quality change”? Whether it is a bra or panties, dirty should be cleaned as soon as possible, the longer the time, the more stains penetrate the material fiber tissue, will be more difficult to clean, and even if the surface can not see the dirty stains, bra a period of time to thoroughly clean once. Especially panties, whether you are visible to the naked eye or not, there will be some secretions on the panties, if not timely cleaning, bacteria multiply open how to wash can not be clean. The actual fact is that you will find a lot of people who are not able to get a good deal on their own. However, you know what? Laundry detergent dissolved in water alkaline is relatively strong (PH high), the dissolution process exothermic, degreasing injury to the hands and laundry detergent mild does not hurt the hands, dissolution is also fast, long time to use the fabric hard; dissolve slowly. General laundry detergent such as synthetic detergent, although the washing power is strong, but the lack of rinsing power. Thus, after the laundry detergent is easy to remain on the clothes. Minefield four: underwear after washing with disinfectant disinfection too clean people, often decided that the underwear simply washing is not clean enough. To put the “fierce” material, underwear after washing also use disinfectant to disinfect. Don’t be a smart ass! The reason why disinfectant is able to kill bacteria and viruses is because its main components are hypochlorite and strong oxidants. These ingredients are not negligible damage to the skin, are strongly irritating and corrosive, and are difficult to wash clean through a basin or two of water. If not clean, people sweating through the skin pores into the body, the light will cause itching, peeling, heavy will cause dizziness and nausea discomfort. Underwear because it is to care for the breasts and pubic area, the skin is weaker, more likely to be stimulated to cause itching disease. The first thing you need to do is to get a good idea of what you’re getting into. I thought to myself, this detergent is very effective! In fact, it is not, many detergent products added fluorescent whitening agent, so that the clothes after washing appear translucent clean, look very white. Brightening whitening agent is a chemical whitening dyes that absorb ultraviolet light can be fluorescent, it enters the body, unlike ordinary chemical ingredients as easy to be decomposed, but and the body’s proteins quickly combined, it is difficult to discharge the body, which undoubtedly increases the burden on the liver, and fluorescent agents on human skin is very easy to produce irritation. Some people think that clothing whitening is not only bright, and clean and sterile, which is a complete misunderstanding.
