Do you know the role of each ingredient in shampoo?

   admit it, three thousand troubles affect your emotions. There is nothing to be embarrassed about. According to a Dove hair care survey, one in four women has missed an activity because of a mess of hair. Eighty-eight percent of women said that a hair can make them confident. Therefore, for many women, choosing shampoo on the shelf is more serious than buying toothpaste and cotton swabs.

  Is the shampoo the only difference in the packaging?

   According to a survey conducted by the British Mintyre Market Research Company in 2008, half of the adults found that the variety of shampoos and conditioners was dazzling. As the leading shampoo category, Pantene has 14 series with different effects as the theme, with a total of 113 products. It is not difficult to see that the shampoo shelves are crowded with different shampoo products, making people wonder where to start.

   Is this good news? Among these various products, most of them are simply different in packaging. Paula Began, a writer for, said: “All shampoo products are basically a cleanser. Only the first 5 to 6 ingredients affect the effect of the shampoo formula.” If you take a quick look at some The ingredients on the shampoo label, you will soon find that all the top ten ingredients on the label look almost the same.

   But what are these ingredients and what do they do? Let’s break down the ingredients written on the back of the shampoo bottle.

  Ingredients on the shampoo bottle:

  1. Water.

   This basic ingredient is as high as 80% in a bottle of shampoo. If there is not enough water, these bubbles of liquid cannot be poured out of the bottle.

  2. Surfactant.

   is basically a cleaning agent. This additive has the greatest effect. It dissolves the dirt and grease around it. Then clean water can rinse them off. Ingredients like ammonium lauryl sulfate and ammonium lauryl sulfate are more easily accepted by sensitive scalp than sodium lauryl sulfate. There are rumors that these chemical components can cause cancer, which is completely nonsense. Although surfactants are irritating, the concentration of ingredients in the shampoo is not high and will not cause any actual harm. Unless you have sensitive skin or you insist on pouring a few gallons of shampoo into your eyes regularly, surfactants will not cause any problems. All shampoos sold today contain conditioners, which can compensate for the peeling properties of surfactants. So you can safely wash your hair every day.

  3. Foaming agent.

  Ingredients such as cocoamide and cocamidopropyl betaine can bring rich foam. These foams complete the entire experience of washing hair. However, foam is only an aesthetic need. A cosmetic chemist at the Cosmetech Research Institute, Nikita Wilson, said, “Foam has nothing to do with the efficacy of shampoo. Manufacturers add foaming agents to shampoos to meet customer expectations.”

  4. An acidic component.

   Your shampoo label says ingredients such as sodium citrate or citric acid. These ingredients are added to maintain the proper pH of the shampoo. The acidic PH value interacts with the slight negative charge on the hair to help the hair cuticle, which is the layer on the surface of the hair, to keep the surface smooth and flat.

  5. Silicone resin.

  Such as simethicone, or any substance ending in “one”. These polymers form a thin protective film on the hair. They help the hair smooth and increase the gloss of the hair.

  6. Polyquaternium.

   is very similar to fabric softener. It can form a layer of fat-like conditioner to drive away static electricity and make hair easier to manage. It also thickens the shampoo formula, which makes it easier to pour out.

  7. Panthenol, fatty alcohol and nut oil.

Be careful of beautiful sunglasses endanger your health

  A beautiful sunglasses can become your own fashionable accessories while protecting the sun. At present, there are a dazzling array of sunglasses of various styles and colors on the market. However, we should remind everyone that the improper selection of sunglasses will not only fail to protect the eyes, but will even endanger our health.

   Liu Qian is working in a foreign company. On her way off from get off work, a stall selling glasses on the side of the road attracted her attention. “So beautiful!” There are very vibrant round or oval styles; there are bright colors that fashion people love very much; there are glasses studded with various line-edge lenses… in this dazzling array of beautiful glasses , Liu Qian suddenly fell in love with a lotus-colored, narrow-lens, small glasses. When I put it on, “Oh,” looks like a custom made for her. The slender glasses, coupled with her fair face of melon seeds, are both playful and fashionable. My colleague also said enviously: “It’s really good, it’s good!” Liu Qian bought these glasses for 20 yuan, feeling like picking a bargain, and she was very happy.

   The fashionableness of the beautiful glasses that I did not spend a lot of money on gave Liu Qian a more dazzling wearing experience than the sun. However, after wearing the glasses for a few days, the original joy was gone, but Liu Qianping added a bit of annoyance. Because Liu Qian, who originally had good eyesight, has always felt a little fuzzy when she sees things in recent days, and sometimes her head feels dizzy. On the suggestion of a friend, Liu Qian came to the ophthalmology department of the hospital for an examination. The doctor diagnosed that this was mainly because the quality of her sunglasses did not meet the standard, the surface was uneven, and there was a certain prism effect that caused the symptoms of asthenopia.

  Illnesses caused by improper selection or wearing of sunglasses are mainly as follows:

   1. Can cause visual fatigue.

  The surface is not smooth, and poor-quality sunglasses with uneven tones can easily induce visual fatigue. In addition, some people, regardless of time and occasion, regardless of the intensity of the light, even wear sunglasses when watching movies or TV. This will increase the burden on the eyes, cause tension in the eye muscles, blurred vision, and symptoms such as dizziness and inability to see for a long time in severe cases.

  2. Can cause sunglasses syndrome.

   Sunglasses syndrome is more common among fashionable young people. They prefer to wear large-frame sunglasses with wide sides, thick frames, and heavy weights. After wearing this type of glasses for 1 to 2 weeks, the wearer will experience numbness in the eye socket or between the cheeks, unconsciousness and other symptoms, and nasal discomfort when breathing, just like a cold. Others felt like insects crawling on their faces, their upper jaw gums were numb, their upper incisors felt unwell, and their eyes were sore. This is because the human facial sensation is mainly innervated by the trigeminal nerve. The infraorbital branch of the trigeminal nerve penetrates through the infraorbital foramen of the infraorbital rim. Sunglasses with thick frames, wide edges and heavy weight tend to oppress the trigeminal nerve Support, thus causing the above symptoms.

  3. Can causecataracts and retinal diseases.

   5% of all the sun’s rays hitting the surface of the earth are ultraviolet rays, which are very harmful to human skin and eyes. Among them, UV-B ultraviolet rays with wavelengths between 280 and 320 microns can cause keratitis and skin cancer, and UV-C ultraviolet rays with wavelengths between 320 and 380 microns can make people susceptible to cataracts and retinal burns. If you wear sunglasses without UV protection, it is more dangerous than not wearing sunglasses. Because the human body has an instinctive response to self-protection. When the eyes are exposed to strong light, the pupils will naturally become smaller, which reduces the ultraviolet energy entering the eyes. Once unqualified sunglasses with darker colors are worn, the pupils will be dilated. The upper glasses do not have the effect of isolating ultraviolet rays. At this time, the eyes are wide open, and the invading ultraviolet energy is greatly increased. The damage to the lens and retina can be imagined.

  4. Can induceGlaucoma acute attacks.

   Because after wearing sunglasses, the visible light entering the eye decreases, the pupils will naturally open, resulting in narrowing of the anterior chamber angle, resulting in poor drainage of aqueous humor, and prone to acute attacks of angle-closure glaucoma over time. Patients may experience redness, eye pain, headache, sharp decline in vision, and even nausea, vomiting and other systemic symptoms. So patients with glaucoma or those with a tendency to glaucoma (family history) should not wear sunglasses.

  Tips for choosing sunglasses

  Small sunglasses have so many health risks. It seems that choosing a good pair of sunglasses is very important. The choice of sunglasses is very knowledgeable. Generally speaking, it should be considered from the following aspects:

  Purchase location:It is best to go to a regular glasses store and choose sunglasses with anti-ultraviolet function produced by regular manufacturers. Most street stalls and hawkers do not have business licenses and optometry equipment. Although the sunglasses they sell are cheap, most of them are fake and inferior products. There are generally no UV protection at all, uneven colors, unqualified surface quality, and structure. Problems such as unreasonable design.

17 kinds of toxic daily necessities endanger your health at any time

  1, airfreshagent

   Air fresheners mostly contain phenol. After the human body is inhaled, it will have difficulty breathing and headaches, and irritate the eyes. After contact with the skin, it may also cause peeling and measles.

   Alternative: Use natural methods to freshen the air, such as growing potted plants or placing grapefruit peels.

  2, bleach

  Most bleaching agents contain a chemical substance called sodium hypochlorite. It is highly corrosive and releases irritating toxic gases. Excessive exposure may cause damage to the lungs and hair. The simultaneous use of bleach and ammonia products (usually used as household cleaners) is especially dangerous because they chemically react and release chlorine gas.

   Alternative: For some difficult-to-clean stains, you can wipe it repeatedly with lemon.

  3. Artificial carpet

   Artificial carpets mostly contain unstable organic compounds, and long-term exposure may cause allergic diseases.

   Alternative: Purchase carpets made of natural fibers, such as wool and cotton.

  4. Dishwashing liquid and washing powder

  Dishwashing liquid and washing powder contain sodium carbonate and phosphate, which can easily cause allergic reactions.

   Alternative: Use phosphate-free products.

  5. Electrical appliances

  Many electrical appliances, such as televisions, computers, and electric blankets, usually contain bromine flame retardants. Bromine flame retardant is released into the air and may be inhaled by the human body, and it is not easy to be discharged from the body. At present, bromine flame retardants have been proven to cause miscarriage of rats and are banned in Sweden and other European countries.

   Alternative: Use a hot water bottle instead of an electric blanket; move the appliances out of the bedroom to avoid inhaling bromine flame retardants while sleeping.

  6. Cleaning powder

  Many cleaning powders used to clean glass windows have a special smell of ammonia. This can irritate and corrode the skin, causing discomfort to the eyes and lungs. Long-term exposure to ammonia can also cause liver damage.

   Alternative: Use two tablespoons of vinegar, add a liter of hot water, and moisten the cloth with a cloth and wipe the glass.

  7. Hair dye

  hair dye can pass through the scalp and be absorbed into the body. Earlier, the European Commission had banned 22 kinds of chemicals for hair dyeing.

   Alternative: Believe that nature is beauty.

  8. Bonfire stove

  Household bonfires can produce dioxins. A study by the University of Leuven in Belgium showed that teenagers who often use campfires have much smaller testicles or breasts than teenagers in other regions.

   Alternative: Avoid making a campfire at home.

  9. Nickel-containing jewelry

  Nickel-containing jewelry and jewellery may cause contact dermatitis.

   Alternative: Try to wear jewelry made of gold or platinum.

Choose a mat and seat according to the four physiques

  The temperature is rising day by day, and the summer heat-relief supplies like summer mats have also become popular. Common summer mats are divided into two categories: straw woven and bamboo woven mats. In addition, there are bamboo charcoal mats, jade mats, cowhide mats and rattan mats, which are dazzling. Health experts remind citizens that all kinds of summer mats have their own merits, and they should not blindly be greedy for coolness and beauty. Be sure to choose the most suitable mat according to your physical condition!

  cold cool pie

  Suitable for people who are afraid of heat and have yin deficiency and internal heat

  ●Ice mat: Fix the special potion in the mat material. People lying on it will have a freezing feeling similar to lying on ice water. If you divide it according to the degree of coolness, the first place is the ice mat.

   Disadvantages: The coldness is large, and it is not suitable for the elderly, children and people with weak physique. Moreover, the surface material and internal filling of the ice mat are made of chemical composite materials, and some people may become allergic after sleeping for a long time.

  ●Jade mat: The second place in terms of coolness is the jade mat made of jade flakes. There is a certain gap between each piece of jade, which increases the air permeability of the mat. It has a calming and calming effect, and has a good effect on irritability and insomnia.

   Disadvantages: It feels cold to the touch, which is more suitable for middle-aged and young people who are afraid of heat and have yin deficiency and internal heat.

  ●Bamboo mats: cool, durable and affordable. The most common ones are water bamboo mats, bamboo strip mats, and mahjong mats strung together with small bamboo pieces and plastic ropes. Mahjong mat is the coolest and most flexible, and has a better massage effect on the back.

   Disadvantages: poor air permeability, high hardness, easy to break when the bedding is uneven. Bamboo mats with inkjet patterns may cause contact dermatitis. It should be noted that due to the high outside temperature in summer and the increase in human body temperature, the thick plastic rope tube in the Mahjong mat is easily volatile and toxic when heated, and is not suitable for long-term use.

  Popular Lover

   The most neutral, most environmentally friendly, suitable for people of all physiques

  ●Cowhide mat: Among the many neutral mats, cowhide mats are the first choice. They are high-end mats, the best made from whole buffalo leather. The cowhide mat is available in all seasons, warm in winter and cool in summer, and has the best sweat absorption, which is very suitable for people who sweat a lot. Because it is made of leather, it will also show its unique softness and smoothness when it comes in contact with human skin. It can be said that “cowhide mat + air conditioner” is the most perfect combination for the bedroom at the moment.

   Disadvantages: the side of the mat is easy to wrinkle after use, the cortex of the dermis is easy to absorb water and evaporates slowly, and mold may grow in the wet season. The price is more expensive, generally above 1,000 yuan.

  ●Rattan Mat: It is hand-woven from rattan leather, divided into three types: ever yellow, ever white, and evergreen (of which ever yellow is the most beautiful and evergreen is the most durable). The rattan mat made of repeated steaming and drying is smooth, soft and wear-resistant, and is not easy to break when folded. Generally, it can be used for decades (the longer the use time, the better the gloss), and it is not easy to grow insects. It is suitable for various people.

   Disadvantages: The price is higher than ordinary summer mats.

  Smell Expert

   is suitable for people with body odor and more body toxins

  ●Bamboo Charcoal Mat: The bamboo of the bamboo charcoal mat has been specially oxidized and has strong adsorption properties. It has the characteristics of sterilization, deodorization, adsorption of dust, fresh air, and pleasant cooling. Although the degree of coldness is inferior to that of bamboo mats, it absorbs more sweat than ordinary mats.

   Disadvantages: darker color. Some “bamboo charcoal mats” are just a layer of charcoal cloth sandwiched between ordinary bamboo mats.

Refrigerators are not safes, 6 tips for preventing bacteria from refrigerators

   Recently, Ms. Li, who lives on Dongfeng Zhong Road, and her family have experienced abdominal pain and diarrhea in varying degrees after eating frozen hairtail in the refrigerator. According to Ms. Li, due to the recent hot weather, in order to prevent food from spoiling, she put all the meat, fish, fruits and vegetables bought from the vegetable market into the refrigerator. What she can’t figure out is, since the refrigerator can keep fresh, why would there be problems after eating?

   The reporter visited some major hospital outpatient clinics a few days ago and found that the citizens who had the same experience as Ms. Li’s family were not the case. Health experts point out that the refrigerator can inhibit bacteria at low temperatures, but cannot kill bacteria, especially in the summer when bacteria are active. Improper storage of food in the refrigerator will increase the chance of food spoilage and cross-contamination, causing “refrigerator food poisoning.”

  High incidence of “refrigerator food poisoning” can causemeningitis

   “From June to August every year, acute gastroenteritis is the season of high incidence. In fact, the crisis is hidden in the refrigerator we use every day.” The director of the emergency department of the hospital, Wang Zhengwei, told the reporter of the New Express News that bacteria are particularly special in the hot summer. Active, they often sneak into the refrigerator with our hands and purchased food. The temperature of the refrigerator compartment is generally 0℃-7℃. This temperature has a significant inhibitory effect on the reproduction of most bacteria. It can delay the time of food deterioration, but it will not kill the bacteria. Among them, some bacteria that love cold environments, such as Escherichia coli, typhoid bacillus, and Staphylococcus aureus, are still very active in the refrigerator, and they continue to multiply and accelerate food spoilage. In addition, raw food will continue to be metabolized even if it is put in the refrigerator, producing toxic metabolites.

  ”Many families buy back a lot of food, no matter whether raw or cooked food is stuffed into the refrigerator and it is finished. They don’t know that the bacteria on the food may be cross-contaminating each other at this time. Take out the bacteria-carrying food from the refrigerator. After the food, if the food is not thoroughly cooked and sterilized, symptoms such as nausea, vomiting, abdominal pain, diarrhea, dizziness, etc. will appear after eating, which is what people don’t know about “refrigerator food poisoning”.” He He, the deputy chief physician of the Hospital’s Department of Gastroenterology and Clinical Nutrition Qing said.

   She also pointed out that there is also a very powerful psychrotrophic bacterium that “lurks” in the refrigerator-Listeria. After being infected, it can cause diarrhea, nasal congestion, and fatigue. It is often mistaken for a cold. As for the elderly, children and immunodeficiency people with weaker immunity, diarrhea may also cause meningitis.

  Preservation time: two days for leafy vegetables and two weeks for eggs

  ” After putting fresh food, fruits and vegetables in the refrigerator, check again in a few days, we will find that the color fades, water loss, nutrient loss, taste deterioration and other problems. This shows that the refrigerator has a good effect on food preservation. Time-effective.” He Qing pointed out that the storage time of leafy vegetables in the refrigerator should not exceed 2 days; the storage time of fruits should not exceed 5 days; the storage time of fresh eggs should not exceed 2 weeks. But no matter what kind of frozen food, the shelf life in the freezer should not exceed 1 month.

  There are tricks to prevent “bacteria”

  1. Do not clean food before putting it in the box

   Some citizens who love to clean, are used to washing food, even with sterilizing detergent before putting it in the refrigerator. In fact, the surface of vegetables, fruits, meat and eggs has its own anti-bacterial “protective film”. After washing off the protective film , On the contrary, it helps bacteria to invade food and accelerate food spoilage. If you find dirt on the skin of vegetables, fruits, eggs, etc., you can wipe it with a cloth, put it in a fresh-keeping bag, and put it in the refrigerator.

  2. Don’t put tropical fruits and vegetables in the refrigerator

Among fruits and vegetables, tropical fruits such as mangoes, bananas, lemons, and lychees are best not to be stored in the refrigerator, otherwise they will be “frostbitten” to accelerate their deterioration. Watermelon, the most common fruit in summer, is best to buy and eat right now. After taking it out of the refrigerator, it is best to cut off the flesh of the melon exposed to the air before eating.

  3. Store raw and cooked food separately

After unsealing cooked meat products such as sausages and grilled chicken, do not put them directly in the refrigerator together with the packaging bag. This will not only pollute the refrigerator environment, but also accelerate its deterioration, and can be placed in a fresh-keeping box. In addition, raw fish and raw meat can also be placed in a crisper and stored in the freezer compartment of the refrigerator.

  4. Cook the food in the refrigerator thoroughly before eating

   Under normal circumstances, heating for more than 5 minutes will basically kill the pathogenic bacteria on the food.

  5. Eat boxed and bottled food within two days after opening

   canned, bottled, canned, Tetra Pak cartons, vacuum-packed beverages, dairy products, meat, poultry, and egg foods are best consumed immediately after opening. If you store the rest in the refrigerator, you should finish eating it within a day or two.

Six commonly used things in the bathroom should be used right

  toilet paper

  The toilet paper is mostly recycled paper, and most of the toilet paper is dyed. The whiter the color, the more dye may be. Some toilet papers of poor quality also contain E. coli and hepatitis viruses. Prolonged contact with skin may cause leukemia and cancer.

   When buying toilet paper, be sure to choose reliable, unbleached toilet paper. It is better to rinse with warm water after using the paper.

  Fragrance agent, disinfectant:

  Many families love to put fragrance and disinfectant in the bathroom. In fact, fresheners are also chemical compounds, which are bad for the body. After cleaning supplies such as disinfectant water evaporate, a large amount of harmful gases will often accumulate.

   It is best not to put deodorant in the bathroom, and keeping ventilation is the most important thing. Do not stack disinfectant and other cleaning supplies in the corners, but put them in a well-ventilated and cool place, and seal them well.

  Plastic waste basket

   Putting a wastebasket in the toilet will greatly increase the speed of bacterial reproduction, turning the toilet into a breeding ground for viruses and a source of infection.

  General paper items can be thrown into the toilet and flushed with water; for sanitary items that are difficult to flush, you can bring your own convenient bag and take it out of the toilet and throw it into the trash can.

  Bubble Bath

Most of the substances in    soap are derived from natural products, but the fragrance in the bubble bath may cause skin inflammation and dizziness. If you take a bubble bath for a long time, the harmful substance “foam stabilizer” may penetrate the skin and breathe into the lungs.

   Take as little bubble bath as possible. Vegetable oil soap is a good choice.


   Gum disease can induce a variety of diseases, such as heart disease and respiratory diseases. The chemical substance “sodium lauryl sulfate” widely used in toothpaste is thought to cause gastrointestinal problems and make the oral cavity easier to ulcerate. The abrasives in toothpaste are also believed to harm the gums.

   When brushing your teeth, don’t think that the more toothpaste, the better, don’t squeeze too much; don’t brush your teeth frequently, control it to three times a day.


Teach you how to identify sterilized tableware

   A kind of sterilized tableware sealed by transparent film has appeared in restaurants in some cities. However, because the market for sterilized tableware is not standardized, some counterfeit and inferior sterilized tableware often appear on people’s tables. In this regard, experts from Heilongjiang Provincial Health Supervision Department reminded The general public pay attention to the following points when identifying qualified disinfection tableware:

  Take a look:Look at whether the outer packaging is printed with clear manufacturer information, such as the name of the manufacturer, factory address, telephone number, and the date and shelf life of the product. Formal enterprises will print themselves on the packaging There will be food labels on the plastic film packaging bags; qualified disinfection tableware should have a good gloss, not be old in color, clean on the surface, and free of food residues, mildew, etc.

It’s convenient to use reusable shopping bags, and it’s also dangerous

  The plastic bag is recognized as one of the worst inventions in the world. Its appearance has forced us to bow our heads in front of the environment and health. Although it is a fact, it still appears by our side as it is now.

   After the “plastic restriction order” was implemented, many people have gradually developed the habit of using shopping bags in the past few years. Recently, a study conducted with the support of the American Chemistry Council showed that repeated use of environmentally friendly shopping bags There will be cross-contamination due to improper use. Although this investigation and research was conducted in the United States, the situation in my country is similar. In real life, we use shopping bags repeatedly, and few people clean them, ignoring the issue of hygiene.

  phenomenon, everything is in the shopping bag

  ”Half of the shopping bags are used more than once a week, and most of the shopping bags are stored in the trunk of the home or car; 70% of the bags are only used for food, and there are also snacks and books; four One in four people put vegetables and raw meat in separate shopping bags.” This behavior, which is summarized by the research funded by the American Chemistry Council, can be seen everywhere in our lives.

   Early in the morning on July 29, Ms. Ma and her wife got up early in the morning and went to the vegetable market on Jianxin Street to rush to the morning market with shopping bags. “It’s cool in the morning and the air is good. Come out for a stroll and buy some food by the way.” Ms. Ma told the reporter with a smile, and enthusiastically opened the shopping bag to let the reporter see what she had bought. Onions, garlic, tomatoes, lean meat, fried dough sticks, some vegetables are wrapped in a thin plastic bag, and some are placed directly in a shopping bag.

  Fearful summer, shopping bags become a breeding ground for bacteria

  ”Bacteria are everywhere. If you don’t pay attention to hygiene when using shopping bags, it’s easier to hide dirt and dirt.” Experts said, “Especially the hot and humid summer is good for the growth of bacteria. Active bacteria are more likely to cause gastrointestinal diseases .”

  If you put everything in the eco-bag and use it repeatedly, it will definitely leave a lot of bacteria. “Especially some germs, such as viral enteritis, are highly contagious and are prone to symptoms such as diarrhea, nausea, and vomiting,” said Shang Jia.

  It is recommended to use it separately and clean it frequently

To eliminate family health killers, refrigerators must be disinfected regularly

  In daily life, many people think that refrigerators are low-temperature appliances, and whether they are disinfected or not has little effect on health. In fact, most microorganisms in the refrigerator under common temperature conditions are only inhibited and cannot be completely killed. In addition, due to the mixing of raw and cooked foods in the refrigerator, it is easy to cause cross-contamination and become a potential health “killer”. .

  According to the inspection of unsterilized refrigerators in use by relevant departments, some refrigerators have a total number of bacteria as high as 10,000 to 30,000 per square centimeter, of which there are hundreds of Escherichia coli per square centimeter, which has become a veritable “contamination”. box”. Therefore, regular cleaning and disinfection of the refrigerator is an important item that cannot be saved, and disinfection should be carried out at least once a month.

  Commonly used disinfection methods

   Before disinfecting the refrigerator, first unplug the power plug, stop the machine, and then take out the food stored inside, defrost and wipe off the inner container and accessories before disinfection. The disinfection method can choose one of the following:

   Use a soft cloth dipped in 75% alcohol or acetic acid solution or 0.1% ceramide solution to wipe, close the door for 15 to 30 minutes, then scrub with water and dry it.

   Spray with 0.05%~0.1% peroxyacetic acid solution, and then close the door for 20~30 minutes.

   Spray with 2% alkaline glutaraldehyde aqueous solution, and then close the door for 30 minutes.

  Precautions during disinfection

   The concentration of peracetic acid solution is too large, which has a certain corrosive effect on metals, so the use concentration should not exceed 1%.

   glutaraldehyde solution has a small odor and slight toxicity, and has no corrosive effect on metals and plastics. Its disinfection effect is better under alkaline conditions. It should be activated by adding 0.3% sodium bicarbonate before use, but the stability of alkaline glutaraldehyde is poor, so it is best to use it now.

  Do not wash or spray the refrigerator with tap or basin water. Because excessive humidity will rust the metal accessories and reduce the insulation performance of electrical parts; around the electrical parts (such as door lights, thermostats, motor junction boxes, etc.), you can only wipe them with a dry cloth.

   Use soft cloth and neutral detergent to wipe off the oil and dirt. The magnetic door seal is very easy to absorb dirt, especially the door seal under the door. Special attention should be paid to cleaning.

The evaporator of some refrigerators is made of aluminum, and acid or alkaline disinfectant should not be contacted on it. If the surface is stained, it should be cleaned immediately to prevent the chemical reaction between acid and alkali solution and aluminum, which will cause Corrosion and damage.

The color of the bed also affects health? How to choose home color

   When we buy bedspreads, we often choose the color we prefer, or refer to personal age characteristics. But did you know that different colors will produce different psychological stimuli, which will have different effects on health? Therefore, when choosing the color of the bedspread, we should first pay attention to its impact on health.

  Red represents anger, enthusiasm, and vitality; Orange symbolizes joy, warmth and warmth; Yellow is bright and warm, giving people happiness , Hope, wisdom; green between the warm and cold colors, harmony, tranquility, and health; blue distant, cool, fresh, purple, noble, mysterious, elegant; pink Delicate and youthful, it is the favorite of little girls; Black sometimes solemn, sometimes silent and empty; white sometimes pure and holy, sometimes fear and sadness.

  It is like using a light orange bedspread for the living room of the elderly, which can induce appetite and help calcium absorption, and secondly make people feel refreshed and happy. Or choose blue to help relieve symptoms such as headaches, fever, and insomnia.

  The bedroom of newlyweds should choose bright and strong red bedspread, which not only adds a festive atmosphere to the room, but also stimulates the nervous system, increases the secretion of adrenaline, and enhances blood circulation. But too much exposure to red can make people feel anxious. Therefore, patients with insomnia, neurasthenia, and cardiovascular disease should not use red bedspreads or decorate their homes, so as not to aggravate the condition.

   People who are emotionally unstable and easily irritable should use tender green bedspreads in their rooms to relax their minds and relieve tension. Generally speaking, the colors of bedspreads are mostly light colors. On the contrary, golden yellow is easy to cause emotional instability, so people suffering from depression and mania should not use golden yellow.

   If the owner of the room suffers from high blood pressure or heart disease, it is best to put on a light blue bed cover to help the blood pressure drop and the pulse to return to normal. In addition, blue is also suitable for white-collar workers who overuse their brains.

  Purple can maintain the balance of potassium in the body and has a soothing effect, but it has a depressive effect on the motor nerve and the heart system. Therefore, patients with heart disease should be cautious in using purple bedspreads.

  Indigo blue affects vision, hearing and smell, and can reduce the body’s sensitivity to pain. Patients whose wounds are recovering after surgery can choose indigo bedspreads and other household items, or simply paint the room in indigo blue.
