If you have the habit of using a thermos to drink water or beverages, you should pay attention!

According to Oriental Daily, a Taiwanese man had been drinking from the same thermos for 10 years, and without realizing it, his health was damaged by heavy metal toxins. He died of complications from pneumonia a year later.

It is understood that the man used the same steel thermos to brew drinks every day. Although rust gradually appeared inside the cup, he continued to use it as usual without replacing it or cleaning it thoroughly.

Ten years later, he began to feel unwell and went to the hospital for a check-up, only to find out that he had lead poisoning, which had caused a serious lung infection.

Despite the medical team's best efforts to save him, his condition continued to deteriorate and he eventually died.

Medical staff believed that the cause of the man's illness might be related to the long-term use of thermos cups, especially those used to hold acidic beverages, which caused toxins to gradually enter the body.

Experts point out that if the thermos contains lead or other heavy metal components, a chemical reaction may occur and toxic substances may be released when it is exposed to high temperature or acidic beverages such as coffee, tea, juice, etc. for a long time.

When these toxins are mixed into beverages, long-term drinking may cause heavy metals such as lead to slowly accumulate in the body, eventually damaging liver and kidney function, the nervous system and immunity.

To prevent history from repeating itself, experts remind everyone:

Avoid using metal thermos to hold these 8 types of beverages (some are speculative warnings): 

Coffee

Tea

Juice

Carbonated Drinks

Dairy

Traditional Chinese Medicine

Herbal Drinks

Alcoholic Beverages

 Follow the following 5 principles for using a thermos cup:

1. Replace the thermos bottle every 1-2 years.

2. Food grade 304 stainless steel, ceramic or glass liner products are preferred.

3. Avoid acidic, hot or dairy drinks.

4. If there is any odour or rust, stop using it.

5. Clean regularly with baking soda or vinegar water to reduce the risk of bacteria and heavy metal residues.
