Have you ever been fooled by these six water related myths?

With the rapid improvement of people's living standards, people now take more and more care of their bodies and pay more and more attention to health preservation. But there are often people who do some pseudoscience in the name of science. Take, for example, the water we usually drink.

This one says that overnight water can't be drunk, that one says that thousands of boiling water can't be drunk, and some say that yin and yang water can't be drunk. But is it true?

1.Weak alkaline water is healthier. Such a theory simply does not exist in mainstream medicine.

Like weak alkaline water, oxygen-rich water, and cool white water, they are all marketing concepts made by merchants in order to sell more water. Drinking water is just to replenish water, and the body's metabolic system will keep the acidity and alkalinity of body fluids in balance.

2.Overnight water. Some people say that the lead in the overnight water exceeded the nitrite standard.

Scientists have done experiments to boil water for a few days, and the nitrite content in it is far below the national standard. In fact, think about it, if you boil the water in the morning, you can't drink it at night? This means that overnight water is drinkable.

3.A thousand boiling waters. The so-called 1,000-boil water is water that has been boiled repeatedly.

They believe that tap water contains nitrites, which are prone to carcinogens under repeated high temperatures. Scientists did an experiment to this effect, taking tap water and boiling it many times, and then testing the only nitrite in the water, which is far below the national limit of 1 mg l. So the water is drinkable.

It is best not to drink overheated water, the water is too hot and easy to damage the esophageal mucosa, the water temperature is not good if it exceeds 65 degrees, and it is best to wait for the water to cool to 50 degrees.

4.Yin and Yang water. What is Yin Yang Water?

It is cool and boiled water. The difference between cold water and hot water is that the molecules in the hot water move fast and the molecules in the cold water bridge move slowly. In essence, there is no chemical change with no physical change.

Therefore, yin and yang water can be drunk.

5.Purified water. They say that the pure water is filtered too clean, filtering out all the minerals, which is not good for the body.

In fact, for drinking water, there are very few minerals in the water, and for the body, it is just a simple replenishment of water, and the replenishment of minerals in the food we eat daily can be.

6.Plastic bottled water cannot be drunk after exposure to the sun. At present, there is no scientific evidence that food-grade plastic packaging causes cancer.

At present, most of the plastic bottles filled with water on the market are made of polyethylene terephthalate, and generally do not add plasticizers. It is a polymer material with a large molecular weight and does not transfer easily to food. It is very safe in temperatures below 120 degrees, and the temperature in the car does not reach 120 degrees even in the hot summer months.

So you can drink it with confidence.

Water is the source of life, healthy drinking water. Don't believe rumors.
