There are hazards. The country's water purification capacity is relatively backward and the economic level does not allow it, the purification standard of tap water does not meet the reference standard of drinking water, that is to say, the microbial content in tap water does not meet the standard, and it is easy to make people sick after drinking.
Therefore, 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, boiling water can kill most of the germs and parasites through high temperature, high temperature disinfection is this principle, the bacteria and parasites in unboiled water are not all killed, and people are easy to get sick after drinking, such as diarrhea.
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.

If it is unboiled water, the bacteria in it will not be killed, and drinking it for a long time will cause diarrhea or other diseases. If you drink it for a long time and there are no problems, then there should be no big problem, and the body has adapted. Of course, it is best to drink boiled water, so that you are not easy to get sick, and I wish you a happy life and a good mood every day.

First of all, it depends on what kind of water quality it is, and it's okay to drink raw water with good water quality. The water quality is not good. Depending on how far you boil, water at around 70 degrees is enough to kill those bacteria, and it doesn't have to be boiled to 100 degrees.
It is okay to use this boiling water to cook rice or noodles after the water is boiled, and at the same time, it is not advisable to boil the water for a long time or many times, which will produce nitrite. The production of nitrite is only possible when boiling water repeatedly, and it becomes hard water (also known as heavy water), and drinking this water for a long time can easily cause stone disease.

Water is very important for the human body, it can participate in life movements, eliminate harmful toxins, help metabolism, maintain aerobic respiration, and much more.
1. Help digestion: The food we eat in our mouths, after being chewed by teeth and moistened with saliva, carries out the digestion process from the esophagus to the stomach and intestines, completes digestion and is absorbed, and these links require water to participate in accelerating the dissolution of nutrients by body fluids.
2. Excretion of waste: The residual waste after the digestion and absorption of food nutrients should be discharged from the body through sweating, respiration and excretion, and these different excretion methods need the help of water to achieve.
4. Balance body temperature: When the ambient temperature is lower than the body temperature, in order to maintain the body temperature and ensure normal physiological activities, the water in the body will be retained in the body due to the reduction of evaporation of the reduced pores; When the ambient temperature is higher than body temperature, water is expelled through the dilated capillary respiratory holes, lowering body temperature. The body functions for survival through the dispersion of water.
5. Maintain cells: water can promote cell metabolism and maintain the normal morphology of cells; Maintain the moistness and elasticity of **.
6. Balance the blood: Water can improve the circulation of blood and tissue fluid, and help balance the viscosity and pH of the blood.
If the human body is not hydrated, it will lead to dysfunction of gastrointestinal digestion, blood delivery of nutrients, and regulation of body fluid concentration, and over time, it will also cause backache and common degenerative knee arthrosis, arthritis and other diseases. Drinking enough water not only reduces the chance of developing the above diseases, but also improves symptoms and diseases such as tiredness, weakness, constipation, high fever, poisoning, dehydration, arthritis, diabetes, liver and kidney stones.
The disadvantages of not drinking water for a long time.
2. Increased likelihood of respiratory diseases.
3. The risk of cataract increases.
Ophthalmologists believe that when the body is dehydrated, the fluid content in the human eye will change, causing degeneration of the protein of the lens of the eye, which will eventually cause the lens to be cloudy and cause vision loss, and increase the chance of cataracts.
4. It is easy to cause cardiovascular and cerebrovascular diseases.
Blood dehydration will increase blood viscosity, affect blood circulation, and people are prone to nausea, dizziness, palpitations, and cause a variety of cardiovascular and cerebrovascular diseases.
5. Poor intestinal detoxification.
The lack of water in the body can easily lead to insufficient digestive juices, affecting the absorption and digestion of food, the human body needs a lot of water for digestion, if there is a lack of water, it needs to be absorbed from other organs, causing other organs to dry, and food is easy to accumulate in the intestines, resulting in body aging.
The chemical composition of water, if viewed by mass percentage, contains hydrogen and oxygen. If you look at it by volume, there are two parts hydrogen and one part oxygen. The water molecules that exist alone are called single water molecules, and the association of water molecules can form double water molecules, triwater molecules, etc. >>>More
All in all, the electric oven is the same as the gas stove, it heats the food by increasing the temperature, as long as you don't burn the food, the food is not harmful, and of course there is no risk of carcinogenic like the microwave oven. >>>More
The white precipitate is limescale, and the main components of scale are calcium carbonate and magnesium carbonate, and the boiled water will produce a large amount of nitrite in the water after repeated long-term heating, these substances are not good for the body, you must know that the human body ingests too much calcium and is easy to get stone disease, and the high content of calcium ions in the blood will lead to muscle weakness, and nitrite is easy to cause cancer. >>>More
Natural Lemonade** Method: Lemon water can quench thirst and dilute the desire to eat, so it can effectively curb improper eating, and with a total of 15 minutes of exercise a day, the effect can be very significant. This method is now the most popular in Japan, and you can achieve the effect by operating it yourself at home, so it is called a housewife-style drinking diet, which is very effective. >>>More
