What is the harm to the body if the water is not boiled?
This question is very difficult to make concrete!
How do you boil water? >(**)
Now people drink tap water. After ordinary water is sent to the waterworks, it is chlorinated to remove impurities such as microorganisms. But at the same time, chlorine interacts with residual organic matter in water to form toxic carcinogenic compounds such as halogenated hydrocarbons and chloroform.
Studies have proved that the content of halogenated hydrocarbons and chloroform is closely related to the change of water temperature and the duration of boiling. When the water temperature reaches 90, the content of halogenated hydrocarbons rises from 53 micrograms per liter to 191 micrograms, and chloroform rises from micrograms per liter to 177 micrograms, both exceeding the national standard by two times. When the water temperature rises to 100 μg, the content of halogenated hydrocarbons and chloroform drops to 110 micrograms and 99 micrograms respectively, which still exceeds the national standard.
If it continues to boil, after 3 minutes, the halogenated hydrocarbons and chloroform levels drop to micrograms and micrograms, respectively, and it becomes safe drinking water.
When the water is about to boil, open the lid of the kettle to allow these substances to volatilize to the maximum, and it is best to boil the water for about 3 minutes.
In addition to the chemicals produced by chlorination, there are minerals and a large amount of carbon oxide in the water, and when heated, harmful substances are also produced.
After boiling for 3 to 5 minutes, the content of some harmful substances begins to increase again, so do not boil for a long time to drink;
In the Beijing area, it is not advisable to cool the boiling water in the kettle, if the cool boiling water is better than the precipitation and put it into the cold water bottle to cool the boiled water, there are more minerals, taste and water quality, thickening, and hardness are higher. Conditionally, you can give it a try yourself.
It is best to drink boiling water when it is cold. The nutrients of boiled water are the same as those of cold boiled water. The longer the boiling water is cooled, the higher the degree of contamination.
The time of use of boiling water should not exceed two days and nights. Cold boiled water for 12 hours.

People with poor immunity will have stomach aches, diarrhea and the like when they drink it.

Drinking like that will make you sick to your stomach, don't drink like that, it's not good for your body!

Stomach ache and possibly diarrhea!

No. Because the purification standard of tap water does not meet the drinking standard of drinking water, the microbial content in tap water does not meet the standard, and it is easy to make people sick after drinking. It is necessary to further sterilize by boiling water to meet the drinking water standard and ensure that you will not get sick after drinking water.
There are many germs and parasites in raw water, and boiling water can kill most of them by high temperature, and high-temperature disinfection is the principle. <

Drinking unboiled water can be serious and can cause the following two problems:
1. Fungal infection.
Unboiled water contains a lot of organisms, pathogens and viruses, the human body has a certain immunity, short-term drinking unboiled water will not cause physical discomfort, if you drink it often, it is easy to be infected with bacteria, causing acute and chronic gastroenteritis, bacterial diarrhea or malaria.
2. Increase the risk of cancer.
Most of the water drunk in the city comes from rivers and lakes, and then filtered and chlorinated by the waterworks to remove a large number of microorganisms and impurities in the water, and at the same time, there are still a lot of organic matter and chloride ions left in the water.

You can't drink water if it's not boiled.
Causes: Because the chlorine in tap water can interact with the residual organic matter in the unboiled water, the risk of bladder cancer and rectal cancer increases.
Experts point out that drinking unboiled water increases the likelihood of bladder cancer and rectal cancer by 21%-38%. When the water temperature reaches 100, these two harmful substances will be greatly reduced with the evaporation of the vapor, if you continue to boil for 3 minutes, it is safe to drink.

Nowadays, many people don't drink boiled water, if you drink boiled water, you will advocate drinking boiled water, so what is the effect of drinking unboiled water, how to see if the water is boiled or not, let's take a look.
What are the effects of drinking unboiled water?
It may cause uncomfortable symptoms such as diarrhea. Generally, the main purpose of boiling water is sterilization and disinfection, only after the water is boiled, the microorganisms in it can be destroyed, and the water that is not boiled will contain a variety of pathogens, bacteria and other microorganisms; There is also a purpose of boiling jujube pure water in order to fully precipitate the impurities such as calcium carbonate and magnesium carbonate, so it is necessary to continue to boil for 3-5 minutes after boiling the water in the rock bucket.
How to see if the water is boiling or not.
To judge whether the water is boiling, you can directly look at the reaction of the water, when boiling water, there will be a whining sound before the water boils, and then when the water temperature reaches 100, the water will boil, and there will be rolling bubbles on the surface of the boiling water, which will cause the vibration of the water, and there will be a large amount of water vapor, because part of the water is also evaporating when it is boiling.
Can you drink cold water in winter**.
Drinking cold water in winter can theoretically help you, but the effect is not great, because cold water also needs to consume calories to heat up in the body, and this kind of square spring mill is not suitable for everyone. The weather is cold in winter, but many people still choose to drink cold water in order to **, because the temperature is low in winter, if you drink cold water into the body, it will slowly heat up to 37 degrees Celsius, which will consume some calories.
Drink cold or hot water.
If you want to drink water, it is best to choose hot water. The effect of hot water is actually better than cold water, but drinking more hot water is also good for good health, first of all, because hot water can promote the burning of fat in the body to achieve the purpose of **; Secondly, hot water can promote the peristalsis of the stomach and intestines, and then promote digestion to achieve the best purpose; Then drinking hot water can promote the metabolism of internal organs, so that the body toxins can be quickly discharged from your body, so as to achieve the best purpose.
If the tea leaves expire, the tea will slowly moisten, some molds breed in it, the tea is soaked in water due to the temperature drop, the bacteria will corrode the soaked tea leaves, and the expired tea leaves cannot be drunk. >>>More
Drinking beer followed by liquor is easy to make people drunk, often manifested as headache, dizziness and other symptoms, this is due to the fact that beer contains a lot of carbon dioxide, beer and liquor together will accelerate the spread of alcohol in the blood, resulting in or aggravation of drunken symptoms. <>

The confirmation of rights needs to be handled in person, and some institutions also accept the entrustment, but a power of attorney is required, and if the rights are not confirmed, the original shares will not be automatically transferred to your account.
That depends on the height of the derailment. The roller coaster's safety belt, seat, whatever, just make sure you don't get thrown out during normal operation. If it is derailed at a high place or at a high speed, it is quite dangerous, and the carriage generally does not use any protection measures for the head, and in that case, the overload caused by the instantaneous braking alone will cause great damage to people, and the body will also be scattered visually. >>>More
