The brain of man is getting smaller. Three drinks that can give you lead poisoning if you put them in a thermos are
When you use a thermos, you need to be careful not to make mistakes that could hurt your health.

Dr. Hong Yongxiang, a nephrologist, told about a guy in his 50s who had been using a thermos cup to bring coffee every day for almost 20 years on the Taiwanese TV show “Doctors Are So Spicy.” Even though the inside liner was old and rusty, he maintained using the thermos.
One day, the man passed out and fell while driving to work, which caused an accident.
The physicians at the hospital did tests and determined that he had significant anemia and that his cerebral cortex had shrunk. But he didn’t bleed within his brain. He was sent to the nephrology section since his kidneys weren’t working as well as they should have been. More tests showed that he had too many heavy metals in his body, which caused lead poisoning. He died of aspiration pneumonia, which is sad.
What Could Happen If You Don’t Use a Thermos Correctly
Dr. Hong Yongxiang said that thermos flasks shouldn’t hold drinks that are acidic or basic, such lemon water, carbonated drinks, herbal medicine, or tea. If the quality of the material is bad, these liquids can leak heavy metals like lead, cadmium, and chromium into the drink, which could cause:
Damage to the liver and kidneys
Anemia in the brain and memory loss
Very serious illnesses of the brain
He Yongcheng, an associate professor at The Chinese University of Hong Kong’s School of Life Sciences, says that the stainless steel coating on the inside of thermoses often has iron and other metals in it. Lemon water and tea are both acidic drinks that can damage the stainless steel covering and add heavy metals to the drink. If you use a thermos with lead or cadmium in it for a long period, it could be dangerous for your health.
Three kinds of drinks that you shouldn’t put in a thermos
The Hong Kong Consumer Council has urged people not to put three kinds of drinks in a thermos:
1.Drinks that are acidic, such as grapefruit juice, orange juice, and acidic dairy drinks
Drinks containing a lot of acid, including citrus juices, can react with the stainless steel liner and cause metal to leak.
Don’t put milk, lemon water, soft drinks, or drinks with a lot of acid in a thermos since they could react with each other and make the drink taste awful.
2.Bubbly drinks Putting carbonated drinks in a thermos might elevate the pressure inside, which could cause it to leak or even blow up.
3.Keeping tea or coffee for a long time If you keep tea or coffee in a thermos for too long, it could smell bad and get stains that make the thermos taste bad and look dirty.
Don’t use cleansers with chlorine, metal brushes, or harsh detergents on a thermos since they can scratch, corrode, and shatter it.
Carefully clean it with a soft sponge, microfiber cloth, or light soap.
Please consider buying a replacement thermos immediately away if you notice any signs of wear, cracks, or leaks.
Pick thermoses from well-known brands that the government has examined for quality.
If the temperature changes too quickly, the material could expand and compress, which would shorten the life of the thermos.
Let the thermos cool down to room temperature for at least 15 minutes before you transition between hot and cold drinks.
Never put a thermos in the microwave because it could catch fire or blow up.
These instructions will help you use a thermos safely and keep your health safe from harmful metal contamination.
