A while ago, the thermos cup represented by the "middle-age crisis" became popular in the circle of friends, and a "health-keeping style" was instantly set off on the Internet. After winter, people who like to drink hot drinks will not leave the thermos.

While bringing warmth to people, the vacuum flask has also become a hotbed of various bacteria: if it is not cleaned in time or used improperly, it will cause a large number of bacteria to hide in it.

Experts remind you that the most neglected corner of hygiene this winter-the thermos cup, teach you to put an end to the hidden health risks of your mouth.

Insulation cup, a hidden health hazard around the mouth

The structure of the thermos cup is relatively complicated. Compared with an open cup without a cover, it is more likely to become a hidden health hazard to people's lips, and the hygiene problem is often ignored by people.

If the thermos cup is not cleaned in time or used improperly, it will cause a large number of bacteria to hide in it. There are many sanitary corners, such as the inner liner, the gap between the bottle cap and so on. During normal washing, it is difficult to reach these places with hands.

The temperature in the thermos cup is suitable and the environment is humid, which is easy to breed various bacteria.

The mouth itself is a "bacterial" environment. Drinking water and capping the bottle... Repeatedly several times a day will make the bacteria attached to the mouth of the cup more and more accumulate in the gap of the bottle cap, and it is easy to enter the mouth with water.

The press-type thermos cup commonly used by children may have greater hidden dangers. Since there is a button similar to a "valve" on the bottle cap, it is necessary to press the button by hand every time before pouring water. If the hands are not clean, bacteria may be contaminated on the buttons, doubling the risk.

The thermos cup should be washed like this

1 Wash thoroughly once a day

This is the fundamental way to prevent odor and stains. Don't just rinse with water when cleaning. Take care of the cup noodles, inner container, and bottle cap.

2Wash the inner tank first and then the bottle cap

Generally speaking, the correct steps are:

Put a small amount of salt in the bottle, shake well with warm water, soak for 5-10 minutes;

Remove the lid, squeeze some toothpaste on the toothbrush, and gently brush the gap between the lid;

Rinse the whole inside and outside of the cup with clean water;

Do not cover the lid immediately after washing, dry it thoroughly before covering it to prevent the stainless steel vacuum flask from getting smelly.

4 kinds of drinks don't put the thermos

Acid drink

If the inner container of the vacuum flask is made of high-manganese and low-nickel steel, it cannot be used for acidic beverages such as juice or carbonated drinks.

This material has poor corrosion resistance, and heavy metals are easily precipitated when exposed to acid. Long-term exposure to acidic beverages may damage human health.

In addition, fruit juice is not suitable for storage at high temperature to prevent its nutrients from being destroyed; and beverages with high sweetness are prone to cause a large number of microorganisms to grow and deteriorate.

milk  

Some people put warm milk into a thermos and take it with them to drink. However, the acidic substances contained in dairy products will react chemically with stainless steel, which is not good for human health.

Microorganisms in milk will also accelerate reproduction at higher temperatures, causing milk to rot and deteriorate, causing discomfort such as abdominal pain and diarrhea.

Tea  

Many middle-aged and elderly people like to pour the thermos cup with hot tea when they go out, and it will not get cold all day.

But if the tea leaves are soaked in hot water for a long time, the nutrients contained in it will be destroyed, and the tea will no longer be mellow and will become bitter.

Chinese Medicine

Some people are used to decoction of Chinese medicine in the morning and take it with a thermos cup to drink it in the afternoon. However, the acidity and alkalinity of traditional Chinese medicine are different, and it is also easy to corrode the stainless steel inner wall of the vacuum flask, causing a chemical reaction, and hurting the body after drinking.

Chinese medicine can be stored for one or two days at a temperature of 25 degrees Celsius. The temperature in the thermos cup is high and it is easy to deteriorate. It is recommended to store it at room temperature.
