As everyone knows, drinking more water is good for health. This concept has long been deeply rooted in most people. Is it as long as the clean water, it’s healthy to drink more?

In fact, if long-term drinking of purified water is not beneficial to the human body, especially to the health of the elderly and children, it will have a certain impact. Pure water, although pure, has no nutrients. Mineral water contains certain minerals.

Is Purified Water Healthy?

With the improvement of living standards, purified water, distilled water, and mineral water have entered everyone’s home. But drinking purified water for a long time will have irreversible negative effects on the health of the elderly and children. Young people who grow up with purified water may feel weak or have advanced cardiovascular diseases.

reverse osmosis

Purified water currently on the market is mainly purified by distillation and reverse osmosis techniques. These technologies were originally applied in the industry. They also remove some healthy elements of the human body while removing harmful impurities from the water such as magnesium, zinc, iron, iodine, other minerals, and inorganic salts.

Healthy drinking water must contain certain minerals. One of the main sources of trace elements required by the human body is drinking water. Long-term consumption of pure water, even if the food structure is adjusted, some trace elements are difficult to obtain from food.

What Is The Difference Between Purified Water And Mineral Water?

The idea of ​​“drink 8 glasses of water a day” has already been deeply rooted in many people. Except for the boiled water we drink, there are many kinds of water in the market including purified water, mineral water, spring water, natural water, and mineral water.

Although there are many types of water, the three main categories of purified water, mineral water, and boiled water are the most popular. So what is the difference between them, and what kind of water should we drink?

1. Mineral water can replenish minerals but infants are unfit for drinking

Mineral water is uncontaminated underground mineral water that naturally emerges from the depths of the ground or is artificially exposed. It contains a certain amount of mineral salts, trace elements, or carbon dioxide gas.

According to the physical condition and the difference of drinking water in the region, the use of suitable mineral water for drinking can be used to supplement minerals, especially trace elements.

In this regard, some people think that children are in a critical period of growth and development need to supplement these trace elements, so they give their baby mineral water.

In response to this phenomenon, Bulgarian medical experts have warned that mineral water with high mineral content will threaten the health of babies!

2. How to drink mineral water

Mineral water cannot be boiled because it generally contains calcium and magnesium that have a certain hardness. At room temperature, calcium and magnesium are in an ionic state, which is easily absorbed by the human body and plays a very good role in calcium supplementation.

If boiled, calcium and magnesium easily form scale with carbonic acid, and precipitate, which loses calcium and magnesium and also causes sensory discomfort. Therefore, the best way to drink mineral water is to drink at room temperature.

It should be refrigerated and should not be frozen. Due to the supersaturation of calcium and magnesium in the mineral water during freezing, white flakes or particulate precipitates will appear.

Drinking frozen mineral water is harmless to the human body. For those who like cold drinks, it’s fine to drink chilled water. However, after all, there is sediment in the bottled water, which affects the sensory index.

3. Purified water contains no harmful substances and no nutrients.

It’s produced by using tap water through a certain production process. The people in the market drink more is purified water. The so-called purified water means that its water is pure, does not contain any harmful substances and bacteria, and effectively avoids the invasion of various types of bacteria.

The advantage is that it can effectively and safely replenish the body with water and promote metabolism. From a scientific point of view, everything has a dual nature. Compared with mineral water, purified water removes harmful substances and removes nutrients from the water.

4. Tap water needs to boil before drinking

According to the inspection by the professional department, the water in the waterworks is completely in compliance with the sanitary standards when it leaves the factory.

However, when it reaches the residents’ homes through water pipes and water tanks, it’s often polluted, so the raw water must be boiled and then drink.

There are some techniques when boil water: after the water is boiled, open the lid and continue to burn for a few minutes to fully decompose the chlorine in the water. The tap water treated in this way can be safely consumed

If the boiling water is left for more than 24 hours, it will become not suitable for drinking. If the household water purifier and water dispenser are not disinfected in time, there is also the problem of secondary pollution.

The Importance Of Drinking Water At Different Stages

1. People should take the initiative to drink water. In addition to three meals, adults generally need to replenish more than 1500mL of water. If the weather is too hot, It’s recommended to drink more water.

Reason: If cells can maintain metabolism with water, they will greatly enhance cell activity, effectively discharge viral contaminants, and enhance the body’s immunity. If the body’s water is insufficient, it will cause the body’s metabolism to be slow, and the body’s waste will accumulate, which may cause constipation, stones and other diseases. It will also make people’s spirit worse.

2. The first cup of water in the morning is especially important. A healthy person drinks at least seven to eight glasses of water a day and needs to replenish more when the amount of exercise is high or when the weather is hot.

When you wake up in the morning, It’s a key moment for your body to replenish moisture. You need to drink about 300 mL of water. It’s recommended to drink boiled water. The temperature is preferably around 30 degrees Celsius.

Reason: When people sleep at night, urine, skin, and breathing consume about 400 mL of water in the human body. After getting up in the morning, the human body will be in a physiological state of water shortage. If you replenish enough water, it can stimulate gastrointestinal motility and prevent constipation.

3. It’s best to drink water for half an hour before meals. The experiment proves that water is drunk from the mouth, and the time for water to enter the human cells is 21 minutes.

Reason: The digestion and absorption of food after entering the intestine need to rely on the digestive juice secreted by the human body. Therefore, drinking water before meals is conducive to the secretion of digestive juice, which is beneficial to the body to absorb nutrients from food.

4. It’s generally recommended that people who sleep at 10 or 11 in the evening can drink a glass of water half an hour in advance.

Reason: People who sleep at 10 or 11 in the evening, 3-4 in the middle of the night or 4-5 in the morning are important periods of human blood secretion, and must have water to participate.

5. It’s recommended to drink a cup of room temperature before the bath. If the bath time is too long, it’s recommended to add water in the middle. It’s best not to go to the sauna after the meal is full.

Reason: Some data indicate that taking a bath for 10 minutes at a temperature of 40 degrees Celsius, the body sweats with 3 cups of water, especially some middle-aged people.

After a full meal, go to a bath or a sauna. Sweat causes a decrease in blood volume and thick blood, which increases the risk of cardiovascular and cerebrovascular diseases.

Some families also start thinking about how to use cleaner, healthier and more nutritious water when cooking and making soup. At present, tap water is commonly used, but there may be secondary pollution and residual chlorine in the pipeline. As a result, many people replace tap water with purified water, which is considered to be cleaner and safer.

As everyone knows, pure water in the process of production, not only remove some harmful bacteria, organic matter, and other impurities but also remove trace elements and minerals beneficial to human health.

In addition, some micronutrients in the water are indispensable for human health and food cannot be completely replaced. Therefore, It’s not advisable to cook rice and make soup with purified water. You can boil the tap water before cooking. If possible, consider using natural mineral water.

How much water needs in an air-conditioned room?

Stay in the air-conditioned room for a long time, it will be thirsty and the skin will be very dry because the humidity in the air-conditioned environment is much lower than in the natural world.

Under normal circumstances, a person needs to drink 1500-2000 ml per day. If the air conditioning time is only a few hours per day, the problem is not big. If you are often in the air-conditioned room, then you should pay attention to add more water, and It’s best to ensure that the drinking water is about 2000 ml per day.

Recently, the saying that “overnight water” cannot be drunk is circulating on the Internet. People know that overnight tea can’t be drunk. After the tea is placed for one night, the nitrite content will increase greatly.

However, even if the tap water is boiled, the chance of being contaminated for a day or two is very small, so you can drink it with confidence.

For healthy people, it’s not recommended to drink purified water. The tap water that is boiled is the best drink. But for some patients with special diseases such as kidney stones, renal insufficiency, dialysis patients are suitable for drinking purified water.

These patients often have hypercalcemia, hypermagnesemia, should not add more minerals, often drink pure water, which is good for health care and adjuvant treatment of diseases.

Does it mean I need to drink more water if the urine becomes dark?

Not necessarily. Because urine darkens can be caused by a variety of reasons, such as hemolytic disease, liver disease, drug effects. If these reasons are ruled out, and it’s indeed a lot of sweat after strenuous exercise or a long period of no intake of water, then it should be replenished in time.

Major Misunderstandings Of Drinking Water

In daily life, be sure to be alert to the five major misunderstandings of drinking water.

1. Tap water can be drunk directly

The water quality of tap water in your region reached the level that can be directly consumed in some developed countries.  In this case, it’s the most economical disinfection method to boil the tap water and then drink it.

2. Bottled water is convenient and hygienic

The bottle will be recycled and reused over a long period of time, which can easily cause fungal infections. The hygiene conditions of those manufacturers who are not regular are more difficult to guarantee.

The boiling water in the water dispenser is easy to cause mineral deposits due to repeated boiling and heat preservation, and also affects health.

3. Purified water is the healthiest

It’s too “pure”, and all minerals and trace elements are filtered out which may not be good for health.

4. “Healthy Drinks” can be safely consumed

Many “healthy drinks” on the market contain sugar, food coloring and food additives. Although there is no clear research showing their harmfulness, it does not mean that they are harmless. Especially for children who are in the growth stage, they should drink less sugary drinks.

 5. Ices water is safe

An important cause of illness in many patients with intestinal diarrhea is the uncontrolled drinking of iced water. Drinking raw water and diarrhea is common sense.

For iced water, many people have misunderstandings. Many people even think that ice is a good disinfection method. In fact, in an ice-cold environment of 0 to 4 degrees Celsius, bacteria still breed and cannot guarantee health.

From a medical point of view, in the summer, the body’s gastric acid secretion is relatively small. A large amount of drinking iced water, cold beer will further dilute the stomach acid, causing intestinal disorders, resulting in many related diseases.
