How often do you wash and change your family’s pillows? This question is difficult for you to answer. Of course, every time you clean, we will clean the sheets, pillowcases, covers, but forget about our closest bedding – pillows. Recently, the Peking Union Medical College Hospital allergic reactions, Professor Yin Jia guest on a TV health program said, “Someone did an experiment, decades of unwashed pillows, the last 1/3 is dust mite feces and corpses, 2/3 is buckwheat bark.” How dirty is a pillow? According to the American Life Science website, there is a whole ecosystem of not only nasty bugs (dust mites) but possibly deadly fungi (Aspergillus) on the pillows people sleep on every night. Study leader Ashley Woodcock of the University of Manchester introduced the pillow as a breeding ground for dust mites that feed on fungi, and the fungi in turn use dust mite feces (and human dander) as a major source of nitrogen and nutrients, and dust mites are one of the “culprits” that cause allergic diseases and aggravate asthma. None of the 19 people regularly wash the pillow insert How often do you wash your pillow and change it? How long did you use the longest pillow? What is the reason for changing the pillow in the first place? 10, the reporter did a small survey on these issues, a total of 19 people surveyed, involved in the survey of 20 to 30-year-old white-collar family, there are 40 to 50-year-old housewives, and 60 to 70-year-old retired elderly, the oldest 74 years old. The results show that: all people will regularly wash the pillowcase, pillowcase, some people wash once every two or three weeks, some people wash once a month, some people wash once every two or three months, but no one has the habit of cleaning the pillow core, at most just get a sun. A pillow there are even used for 30 years in the use of the pillow, the older the person, the longer the use of time. 19 people, Huang Da Ma’s pillow use the longest time, there are more than thirty years. The old lady, 74 years old, is a clean person, once a month to clean the sheets, covers, pillowcases and other bedding washed once, but not on the pillow core. The company’s main business is to provide a wide range of products and services to its customers. The pillow cores used by Auntie Wong are made by herself with cotton wool and rags, and they have not been changed because they have been sleeping comfortably. She added: “In fact, most of the elderly people in the village are like this and have been sleeping for decades.” In addition to Ms. Huang, Ms. Li and Ms. Yi’s pillow cores have been used for a longer time, one for more than a decade and one for 10 years. In contrast, twenty to thirty years old white-collar family, change the pillow core change more diligently, the average number of years for 2 to 4 years. Only 2 people 1 to 2 years to change a pillow insert. Dust mite fungal spores, patients due to pillow allergies The survey also found that all people change the pillow insert is not because they think it is unhygienic, but because it is uncomfortable to use, moving, fresh and other reasons to change. Although, this survey did not find anyone sick from the pillow, but it is not uncommon for people to get sick from the pillow in the clinic. Wang Huiying, deputy chief physician of the allergy (allergic reaction) department of the Second Hospital of Zhejiang Medical University, said that in the clinic, she still encounters, from time to time, patients who do not have coughing, sneezing and other allergy symptoms after changing their pillows. In cases like this, Wu Liming, director of the Department of Dermatology at City No. 1 Hospital, has also encountered many. Director Wu said, “Clinical findings, 6 months to 3 years old infants and children skin exposure reactions, 70%-80% is eczema, and most of the eczema is related to allergies.” ”Pillows, air conditioning vents, mats are easy to parasitize dust mites indoors, and easy to ignore the hygiene corners, these three inside the pillow has the highest use rate, the highest degree of neglect, so, from time to time in the clinic will encounter patients with allergies due to pillows.” Director Wu said. Chen Zhiling, director of the Department of Otolaryngology at the City Hospital, also said that the pillow is indeed a very easy place to host dust mites, some laboratories to do dust mite culture experiments, is to use the pillow. On the other hand, many people like to wash their hair before going to bed, which actually provides the conditions for dust mites to multiply. Director Chen said: “Some people just wash their hair, it is generally difficult to blow dry, often hot and humid. This is the kind of environment that dust mites like best.” According to the American Life Science website, Ashley of the University of Manchester? Woodcock found that there are millions of fungal spores hiding in the pillows we touch every day. Among them, the most common is Aspergillus, a common fungus that travels with the air and can induce a variety of diseases, such as causing asthma to worsen, especially in patients who have suffered from asthma for years, and allergic sinusitis. Pillow every year to change a pillow use how long to replace the appropriate? Shen Huahao director recommends changing one every year, especially people who have their own respiratory diseases, allergic diseases. If there is no underlying disease, can be relaxed to 3 years to change one. Decades, decades, really too long. It is recommended to change a pillow insert a year, also related to the rate of reproduction of dust mites. Dr. Wang Huiying said, “The temperature suitable for the growth of dust mites is 20 ℃ ~ 25 ℃, the relative humidity is 65% ~ 80%, a dust mite from small to large its survival for 2 ~ 3 months.” ”There is ultraviolet light in sunlight, which does have a sterilizing effect, but what causes human allergies, in addition to live dust mites, there are dust mite carcasses and feces. Exposure can only kill the dust mites, but their bodies remain on the pillow, and people will be allergic to them as soon as they touch them, so exposure is a cure.” Dr. Wang said. How to remove dust mites from the pillow If it is a buckwheat pillow, Dr. Wang recommends pouring out the buckwheat inside, and then, the buckwheat and pillowcase are dipped in boiling water above 55 degrees Celsius, dipped for more than 10 minutes, and finally is to get exposed to the sun, and keep patting. Chen Zhiling director suggested that people with allergic diseases, try not to use down products pillow insert, easy to allergic. If you must use, it is best to use a high-density woven pillowcase, the pillow core wrapped, and every 2 to 3 months, at least once exposed to the sun, the sun, but also to keep patting. Today, in many shopping malls supermarkets appear anti-mite anti-bacterial pillows. The merchants claim that the fabric of the pillow is made of high-count, high-density cotton fabric that has undergone anti-mite and anti-bacterial treatment. Professor Yin Jia of the Allergic Reaction Department of Peking Union Medical College Hospital was a guest on a TV health program, and also mentioned that in Europe and America an isolated fabric will be used to wrap the pillow core.
