It is cold in winter, and many people like to drink some hot water, which can not only help keep warm, but also protect the stomach. But the cold temperature often makes the hot water cool quickly, so it is very troublesome to burn it again if you want to drink hot water. Therefore, people often use thermos cups in winter. Whether at home or in the office, thermos cups are very common. However, what many people don't know is that if the thermos cup is used improperly, it will become a hotbed of bacteria and endanger health. How to use a thermos cup to be healthy?
1, don't pack carbonated drinks.
Carbonated drinks are often drunk in people's lives. Although carbonated drinks have long been proved to be harmful to health, many people still choose to drink carbonated drinks because of their refreshing taste.
Some people like to put carbonated drinks in a thermos. I'm sure everyone here has done this, but from the perspective of safety, never put carbonated drinks in a thermos.
Carbonated drinks contain a lot of carbon dioxide. If carbonated drinks are poured into the thermos cup, the pressure in the thermos cup will rise sharply. If the material quality of the thermos cup is not up to standard, it may even cause the thermos cup to burst!
In addition, the acidic substances of carbonated drinks will react chemically with the cup wall of the thermos cup, which will not only reduce the taste of carbonated drinks, but also corrode the cup wall of the thermos cup, thus greatly reducing the thermal insulation performance of the thermos cup and shortening its service life. And the produced chemicals must not be drunk by human body, otherwise it will be harmful to health.
2. Don't make coffee.
Coffee is a very familiar drink, because it has a refreshing effect. In winter, coffee is the best drink to help us stay excited.
Of course, you should choose to drink hot coffee when drinking coffee. Drinking a cup of hot coffee in a leisurely afternoon is not only refreshing, but also very pleasant.
In order to drink steaming coffee at any time, many people will put the cooked hot coffee in a thermos cup, so that the coffee is still hot when they want to drink it, so many people's thermos cups will be used to hold coffee.
In fact, putting hot coffee in a thermos cup is a common sense mistake that people often make, because thermos cups are very unsuitable for holding coffee.
In fact, coffee and carbonated drinks are similar, that is, they all contain acidic substances. Coffee contains a substance called tannic acid, which will react chemically with the wall of the thermos cup, thus corroding the thermos cup, greatly shortening its life and making its thermal insulation performance worse and worse.
If you don't clean the mug after making coffee, dirt will form in the mug, which is not only difficult to clean, but also harmful to health.
In daily life, many friends like to sit on soft sofas and feel very comfortable. But from the point of health care, sitting on the soft sofa for a long time may bring some harm to the body. Next, I will take you to understand the dangers of sitting on a soft sofa and some daily necessities that you have neglected.
Soft sofas are easy to cause diseases.
Experts say that the sofa is soft, people will lose their balance when sitting on it, and their waist will bend with it. Over time, it can cause lumbar scoliosis or kyphosis, resulting in symptoms such as vertebral body injury and lumbar disc herniation.
Sedentary soft sofa can also lead to excessive growth of local muscle fiber tissue, which makes nerves, blood vessels and so on. Being squeezed makes people feel pain and even makes muscles atrophy. In addition, the sedentary soft sofa reduces the stimulation to the brain, and also dulls the vitality of the brain and affects thinking.
So sitting on the soft sofa for a long time is a very unhealthy lifestyle, which will bring harm to the body. If you are still sitting on the soft sofa, you should choose a healthier sofa for yourself as soon as possible to protect your health.
After 6 months of soft towel, the bacteria increased 1 10,000 times.
Someone once made a survey on towel usage habits in five cities, and found that 65% of the respondents didn't know the correct way to use towels, and 35% of them sometimes had slight itching on their faces, but they didn't know that it might be caused by towels. Due to the restriction of living habits and economic production conditions in the past, the consumption level of towels in China has been at a low level, only per capita 1.2/ year. In contrast, Japanese towel consumption is six times that of China, and European and American countries are seven times that of China. In developed countries, towels are not only bathing tools, but also reflect people's pursuit of quality of life. In their bathroom, there will be five or six or even a dozen towels neatly hung. Every family member has his own towel, which is clear about washing his face, hands and feet.
In the above investigation, the colony of 167 towels was detected. The results showed that most towels contained Staphylococcus aureus, Candida albicans, Escherichia coli and other bacteria. Among them, Staphylococcus aureus often causes local purulent infections such as incisions and wounds, and can also cause systemic infections such as pneumonia, pseudomembranous enteritis, pericarditis and even sepsis. Escherichia coli is easy to cause severe diarrhea and septicemia in infants; When human immune function is low, Candida albicans may invade cells and cause diseases.
An expert in Beijing also did an experiment: new towels, towels that have been used for 3 months and towels that have been used for more than 6 months were cultured separately. The results showed that the colony order of new towels was 65,438+000 per square centimeter, and that of towels used for 3 months was10,000. However, after using the towel for 6 months, almost all the Petri dishes are colonies, which are estimated to be around/kloc-0.000 million, mainly Gram-positive bacteria. The latter is originally the normal flora of human intestine, but if it invades the wound, it may cause infection.
The above experiments all suggest that: First, different towels should be used to scrub different parts, because the normal flora in one part may cause disease in another part of the human body. Second, the wrong use of towels may be harmful to the human body, especially for the elderly with chronic diseases or infants with immature immune systems, which may cause infection.
There are three main reasons why towels have become a place to shelter evil people and shelter evil practices. First, cotton fiber, the main component of towel, is tubular structure with hollow cells, which can store water. Humidity is the most important condition for bacteria to survive. Secondly, towels are often placed in hot and humid bathrooms, with poor ventilation and breathability, and lack of direct sunlight. Such an environment is suitable for the growth of bacteria. Third, oil, dust, dander, mites, sweat and other excreta on human skin will accumulate on towels. If it is not cleaned regularly, it will easily lead to bacterial reproduction and cross infection.
Towels should be used separately for everyone, not for different parts. They should be replaced at least once every three months. Consciously clean at ordinary times, and those who have the conditions can use the following three methods for disinfection:
1. Sterilized by microwave oven, the bacterial eradication rate reached over 98%. Put the cleaned towel into a special fresh-keeping box for microwave oven, and microwave for 3-5 minutes.
2. Disinfection with neutral detergent can keep the softness of towels.
3. High temperature disinfection, boiling in boiling water for 5 minutes or steaming in pressure cooker for 10~ 15 minutes will affect the color fastness and strength of towels, so it is not recommended to use them frequently.
Buying towels is also a science. Buying the right towel can also reduce the harm to health. Look at the appearance: whether the towel is sewn neatly, whether the terry is flat and whether the color is uniform. Second, feel: dry and hard towels will hurt the skin. High-quality towels feel fluffy, soft and non-greasy, soft and elastic in the fist, and do not lose hair when flapping. Three smells: ensure that qualified towel printing and dyeing materials will not be stained with equipment oil stains or other dirt, and there is no odor. Four ways to absorb water: a good quality towel can be absorbed quickly by dripping water drops; Inferior towels are slippery on the face, do not absorb water and do not decontaminate. Finally, consumers should try to buy towels in large shopping malls, supermarkets or specialty stores. Qualified towel products should have standardized identification, and indicate the manufacturer, place of origin, contact number, trademark, implementation standard, washing method, etc.
Improper use of rag is equivalent to eating bacteria?
Some people regard a small rag as an "indifferent thing", using worn-out sheets, towels and even clothes and trousers. When it is dirty, just wipe it and throw it in the corner when it is not in use. A few families use rags to wipe tables and chairs, chopping boards, knives, chopsticks, pots and pans, thinking that as long as the rag is pressed down, the surface is clean without anything. Even the washed dishes and chopsticks should be dried with this rag.
According to the research, there are 10000 to 1000000 bacteria and 10000000 Escherichia coli on every square centimeter of rag. As an indicator of human and animal feces pollution, Escherichia coli often contains pathogenic salmonella, Vibrio parahaemolyticus and other intestinal pathogenic bacteria and viruses. If you are very hygienic in many aspects, but you don't pay attention to the hygiene of the rag, you can also. "
For most families, improper use of rags is not unconditional, but a lack of health awareness. Because kitchen rags and dishcloths are often accompanied by food residues, they are good places for bacteria to breed, so they should be cleaned frequently and dried after use. It is recommended that you boil or soak in boiling water twice a week 1-2 times.
Step 3 don't make tea
People have enjoyed drinking tea very much since ancient times. As one of the three major beverages in the world, tea not only has outstanding taste, but also has extremely high nutritional value. In particular, tea polyphenols contained in tea is a natural antioxidant, which can hinder the aging of the body and help us stay young.
Drinking tea has many benefits. People love tea very much in life, so we must drink hot tea when drinking tea. Once the tea leaves are cold, they will form sediment, and the taste will be greatly reduced. Therefore, in addition to ordinary hot water, people use thermos cups to pack the most drinks.
In fact, what many people don't know is that thermos cups can't make tea at all! If you want to make tea, you'd better choose a cup.
Why can't I make tea in a thermos? In fact, the temperature in the thermos is still relatively high. If the tea leaves are soaked at this temperature for a long time, the nutrients of the tea leaves will disappear, and the tea polyphenols, tannins and other substances contained in the tea leaves will be leached in large quantities, which will make the tea color thicker and bitter, and the tea taste will no longer be mellow.
Moreover, if the tea leaves are soaked in high temperature for a long time, the aromatic oil in the tea leaves will evaporate rapidly, which will reduce the fragrance of the tea leaves, destroy the vitamin C contained in the tea leaves and greatly reduce the nutritional value of the tea leaves. At the same time, the tannic acid in the tea leaves will react chemically with the thermos cup to generate heavy metal substances, which is also very unfavorable to human health.
If you make tea in a thermos cup for a long time, it will form tea stains that are difficult to clean and look dirty, so don't make tea in a thermos cup.
4. The thermos cup should be cleaned frequently.
The thermos cup is made of stainless steel, which is not easy to rust, and compared with other cups, the service life of the thermos cup is also very long. People often don't clean the thermos cup after using it, or just rinse it with water.
It seems that the thermos cup is clean. In fact, if the thermos cup is not cleaned frequently, it contains a lot of bacteria invisible to the naked eye.
There are often some tea stains at the mouth of the thermos cup. Tea stains contain metal substances such as cadmium, lead, iron, arsenic and mercury, which are very harmful to health. Therefore, the thermos cup should be cleaned frequently, and every time it is cleaned, no place can be missed.
When cleaning the thermos cup, you can put some salt in it first, because salt has a good bactericidal effect, which can effectively remove the tea stains that are difficult to remove in the thermos cup, and then clean the thermos cup with clear water from the inside out, so that the thermos cup can be cleaned.
Conclusion: In the cold winter, everyone wants to drink hot drinks. In this case, thermos cups are often used. Many people will put carbonated drinks, coffee and tea in the thermos cup, but doing so will not only corrode the thermos cup, but also form many bacteria, which is harmful to human health. I hope you will pay more attention when using the thermos in the future and clean the thermos frequently.
