Boiling water is a process we use daily to purify it and ensure the safety of hot drinks such as tea, Nescafe, anise, and others. However, there is an ongoing question about the impact of repeated boiling on health. In this report, Dalili Medical reviews scientific opinions and reveals some surprises related to boiling water more than once, which may be shocking to some. There is a popular post on social media warning of the dangers of drinking water after boiling it twice or more, indicating that repeated boiling can lead to the loss of health benefits and turn them into serious harm. So what is the truth behind this?

What is distilled water?

 

Sometimes, it is necessary to purify regular water for specific purposes, and separate the salts and other substances in it. The water resulting from the distillation process of regular water is known as distilled water, the proportions of which can vary according to the circumstances, and can be mixed with other liquids. Each percentage of distilled water and its components are used for specific purposes. Distilled water is the vapor of water that has been boiled and then cooled to return to its liquid state. Some people believe that distilled water is the purest type of water you can drink. However, any water, whether it is a natural spring, distilled water, or even regular milk, can contain trace amounts of minerals, bacteria, pesticides, and other contaminants. The distillation process removes all impurities from the water, and removes more than 99.9% of the soluble minerals in it.

**The difference between distilled water and boiled water**

 

Boiled water is heated only until it reaches its boiling point. While to prepare distilled water, the water is first boiled until it evaporates completely, and then the resulting vapor is condensed in a separate container. Distilled water is considered cleaner and purer than boiled water, as the latter does not undergo a comprehensive purification process and may contain chemicals, minerals, and other dissolved solids. Although boiling can help remove some microorganisms, it does not guarantee the purity of the water.

**Is distilled water completely free of minerals?**

 

No, the minerals in tap water are limited. The body gets most of the minerals it needs through food. As long as your diet contains adequate amounts of calcium, magnesium, and potassium, using distilled water will not cause you any problems in this regard.

What are the advantages of distilled water versus boiled water?

 

Depending on where you live, distilled water may be better for you than boiled water. If the water in your city is contaminated with harmful chemicals or pesticides, it is better to drink distilled water, but the best course is to buy water so that your health is not affected.

Contaminants removed by boiling water** If your tap water source is likely to be contaminated with microbiological impurities such as bacteria, viruses, and protozoa, we recommend boiling it. Boiling ensures that the water reaches a temperature of 100 degrees Celsius and even more. When bacteria are exposed to temperatures above 65 degrees Celsius, they will quickly die. Therefore, boiling water destroys these microorganisms.

If your tap water contains minerals, salts, or other impurities such as heavy metals and chemicals, boiling will not remove them. In fact, boiled water is more saturated with these impurities; because some of the water has evaporated and the impurities remain in it.

**Is distilled water good for drinking?**

 

Yes, you can drink distilled water. Despite its pleasant taste, distilled water lacks minerals such as calcium and magnesium that are found in tap water. Since distilled water does not contain minerals of its own, it tends to absorb them from any surface it comes into contact with to maintain the balance of the composition. So, when you drink distilled water, your body may lose trace amounts of minerals, including those found in your teeth. However, since you get most of the necessary minerals from your diet, drinking distilled water should not significantly affect the levels of these minerals in your body.

**What is the difference between distilled water and city water?**

 

Regular water or city water is characterized by being free of impurities or harmful salts. However, it is not completely pure and contains salts such as calcium and magnesium. These salts, which are also found in mineral water, do not pose a risk to the health of the body, and may sometimes be necessary to improve organ function. However, the sediments resulting from these salts can pose a threat to human health in some cases.

**The main difference between distilled water and regular water**

 

The main difference between distilled water and regular water lies in the amount of impurities present in them. After the distillation process, the percentage of impurities in regular water is significantly reduced. It is important to note that drinking distilled water does not cause harm to humans. However, if this habit continues for a long time, the lack of necessary salts in distilled water can lead to digestive problems in the consumer.

What are the properties of distilled water?

 

Distilled water is water that has been heated to boiling point, which causes it to evaporate and remove the impurities present in it. The vapor then condenses back into its liquid state as pure water, while impurities are left behind as residue. Water distillation systems remove biological contaminants such as bacteria and viruses, as well as organic and inorganic chemicals, heavy metals, volatile gases, and other pollutants. It is important to note that distilled water is completely free of solids, minerals, and trace elements. It is also characterized by purity, naturalness, and health. In fact, distilled water is considered a standard used to measure the quality of other water.

The most important uses of distilled water**

 

Distilled water is free of any dissolved materials, making it non-reactive with some chemicals. This property has made manyLaboratories and research centers rely on distilled water for their activities, such as dissolving chemicals or cleaning laboratory equipment. In addition, distilled water is widely used in the pharmaceutical industry and medical applications due to its high purity. A simple example of the use of distilled water in the medical field is its use in injections to dissolve injectable drugs.

**Process of preparing distilled water**

 

To prepare distilled water, a distillation device must be used, which is a complex system that allows water to be boiled and concentrated at the same time. The process begins by adding water to the boiling chamber, then the device is turned on to heat the water until it reaches the boiling point. The water turns into steam, which travels through a special passage where it is cooled and returns to its liquid state. The resulting droplets are then collected in a clean container.

During this process, impurities that cannot be evaporated remain in the liquid state inside the boiling chamber. Any impurities that may evaporate and condense in the final stage of distillation, when the water exits the opening, are filtered out. A carbon filter is usually used for this purpose. By completing the distillation process, completely pure water is obtained.

**The process of preparing boiled water**

 

Boiled water is defined as water that has been heated to boiling temperature, and the process of preparing it is done in a simple way that matches its name. A heat source is used to raise the temperature of the water until it reaches the boiling point. The easiest way to do this is to boil tap water in a pot or pan on the stove. Increase the heat and wait until the water starts to boil, as this is a sign that it has reached the boiling point, and you will also hear the sound of bubbles.

After that, let the water boil for one minute. If you are in a high area, it is necessary to wait for three minutes due to pressure changes. If your goal is to eliminate microorganisms, you can use the water after boiling it. Remove the pot from the heat and let it cool, then store it in a clean, closed container.

Distinguishing distilled water from regular water** In recent years, many companies have sought to provide distilled or pure water, and you can find this water in the form of mineral water sold in some stores. However, the distillation process is expensive and time-consuming, which means that sometimes the water available may not be true distilled water. Distilled water can be distinguished from pure municipal water by its taste. If you are someone who is sensitive to a certain taste of water, you may notice a difference in taste when you taste distilled water. Additionally, since distilled water loses conductivity, flow meters can be used as another way to detect this difference.
