If you have to mention the most bacteria and areas in the house, most people will think of: toilet, trash ... However, there are familiar items we contact closer, more than withCan be dirty than the toilet without knowing it.

Summary of data from many studies and self -survey, Dr. Hoang Xuan (China) has listed the top 10 items containing bacteria but few people are interested in cleaning the most frequent cleansing.That is:

Number 10: Thermos bottle

"Handy, familiar but also full of bacteria and very rarely hygienic"What is Dr. Hoang Xuan talking about this item.According to him, many people may not realize that mouth contact with objects, especially repeated many times a day creating an ideal environment for bacteria to multiply.At the same time, it also facilitates infections to harm human health.

He reminded him to clean the thermos at least once a day.You can use baking soda or sodium percarbonate as two detergents and use a soft cleaning brush to achieve twice the results that cost only half the effort.When drinking, if possible, use a separate cup and then rinse or stay away from your mouth a little, wipe the tank after drinking.

Number 9: Mouse and computer keyboard

Many people wipe the computer screen and carry the computer to the toilet but forget how the mouse and the computer keyboard are dirty.In addition to accumulating dirt, they are easily contaminated through hands, when we eat in front of the computer, even due to daily sneezing.

Dr. Hoang Xuan said that American researchers have discovered the number of bacteria on the keyboard and computer mouse if not cleaning for a long time is more dirty than the toilet.Specifically, bacteria in the keyboard can be 20,598 times more than on the toilet and bacteria in the mouse are 45,670 times higher than the handle/button to discharge the toilet.He advised to clean the mouse daily and discuss 3 days to a week, especially in the keys.

Number 8: Shower head

The shower head is what we use to clean the body daily, we are very dirty and rarely clean.Dr. Hoang Xuan reminded it to have a structure that easily accumulates dirt, wet so it is an ideal environment for bacteria to multiply.When used, it can cause an infection at the body, especially for people with poor immune systems.

He said:“The Manchester University's study in the UK showed that the water holes on the shower will accumulate every three months and the bacterial content in the shower is not clean higher than the water in the toilet after discharge.So bathing with dirty shower head is no different from you taking a bath with water in the toilet. ”

Number 7: OP

The amount of bacteria in the cutting board is even worse than the shower because they are constantly exposed to raw meat and other ingredients, so it is easy to stick to dirt and bacteria.Especially if you do not clean the cutting board immediately after use.The more harmful to the wooden cutting boards are easy to absorb water, scratched and mold.

Dr. Hoang Xuan said:"According to the study, an average household using a cutting board for 7 days will have more than 200,000 germs per square centimeters. On a wooden cutting board used for two months, the total number of germs on it is 12 times the tankBridge ”, therefore, you need to wash the board immediately after use, use chemicals to clean properly, to dry, avoid mold and change the cutting board periodically"

Number 6: Sleeping pillow cover

"The dirty items but the least hygienic attention in the bedroom is usually sleeping pillows"- Dr. Hoang Xuan said.Because you will be close to the pillow every night when you sleep, but the amount of oil secreted from the face and scalp as well as dandruff on the hair will accumulate on it every day.In particular, many people because they are too tired without removing makeup, washing their face after a long day lying on the pillow.It can also be dirty by sweat, skin care, pet ...

A study in the US shows that if the pillow shell is not washed for a week, the amount of bacteria sticking to them is 17,000 times higher than the toilet.Naturally dirt and bacteria will also exist inside the knee.The advice is to wash or replace the shampoo at least twice a week.After 6 months should be replaced once or whenever it is too dirty.

Number 5: Rags

Although rags are often attached to dirt, they may be much dirty than you think.Dr. Hoang Xuan quoted his research and said:"The amount of bacteria on the rag is up to 875 million per square cm, even more than the toilet! These bacteria include E. coli bacteria, Staphylococcus aureus, Streptococcus ... and they are very dangerous.".

But because it is a rag, many people do not focus on cleaning or cleaning immediately after use.He advised soaked in bleaching or high temperature water to disinfect regularly.If the rag has yellow or black stains, you should throw away immediately.

Number 4: toothbrush

Everyone uses a toothbrush to clean their teeth every day but many people ignore the cleanliness of the toothbrush.The toothbrush has a thick hair that is easy to stick to dirt.In addition, the bathroom is moisturized and not ventilated for a long time, making the bacteria on the toothbrush even higher than the water in the toilet, making your teeth more dirty.

Dr. Hoang Xuan advised to clean the brush daily, before and after use.Should replace the brush every 6 - 8 weeks or whenever mold, damage.Especially, it is not advisable to keep it near the toilet area, sewer and priority in a clear, windy or sunny place.

Number 3: Mobile phone

The mobile phone turned out to be a portable bacteria but we were always close.In addition to taking photos, contacting and chatting, using when eating, many people also bring the phone to the toilet, making it even more "paradise" of bacteria.

Research by Stanford University showed that a normal mobile phone is 18 times higher than that of bacterial infection than a toilet in public toilets.Specifically, every 1 square inch on the phone contains about 25,107 bacteria, compared to the toilet is 1,201 bacteria/1 inch square."You should clean the phone after going home, before eating and after going to the toilet to avoid the phone becomes a breeding place of bacteria," Dr. Hoang Xuan said.

Number 2: towels

Towels are the perfect shelter of bacteria by each use, we move the natural bacteria on the skin to the surface of the towel, along with countless other bacteria we carry on people.Plus the dirty and wet environment in the bathroom makes it possible for sentient beings to proliferate.So you should wash towels after each use, then dry in a breathable place, preferably sunny.Replace every 3-4 months or whenever yellowing and mold.

By studying the University of Arizona (USA), nearly 90% of the towels are contaminated with coliform bacteria (the form of intestinal bacteria - these are creatures that can indicate the presence of disease -causing bacteria in water.).It is worth mentioning that 14% of them contain E.coli bacteria.They also discovered the traces of Salmonella - bacteria to make food poisonous.Dirty towels also cause dermatological diseases.

Number 1: washing machine

The champion of many bacteria but few people know in the house belongs to the washing machine.The residues from washing powder, stains as well as grease sticking on clothes will form plaque, sticking to many different parts on the washing machine.The washing machine cage can contain a lot of bacteria larger than the toilet if not cleaned regularly.

Research by the University of Arizona (USA) concluded:“Inside the washing machine is full of bacteria.If the washing machine is not cleaned regularly, it is likely that the clothes will be infected with bacteria and during washing, causing cross -contamination.After washing the underwear, there are about 1 billion E. coli bacteria ”.
