What is boiled water for?

The man uses water every day, knowing very little about it. When we talk about the effects of water on health, most of the time we think about its effect when we drink it. But even visually clear and clean water is not always perfect.

That is why many people boil her. Let’s look at how our body boiled water: its benefits and damages are slightly different from those of raw water.

How it affects boiled water

All the water used to drink, cook drinks and plates (especially fruits and vegetables), brush your teeth and open wounds should be boiled. Boiled and subsequently cooled water is used to take care of the body of babies, children with weakened immunity and to clean toys and everyday objects that children can take to their mouths. If for some reason the water cannot be boiled, bottled water is recommended.

According to a WHO study, infectious germs transmitted by water, such as viruses, bacteria and unicellular organisms, die when they remain at about 80 ° C for 1 minute.

Chemical composition of boiled water

Hot and hot water hygiene limits should be respected in all places where it is served: taps, showers, etc. In the case of bottled drinking water (not mineral water, babies water, spring water, for which a different norm is applied), restrictions at the extraction point must be respected.

Physicochemical and organoleptic characteristics (tests with boiled water, whose benefits and damages are still being studied, indicate a variation of these values):

One of the most common errors is to try to eliminate substances from water that cannot be eliminated boiling it. For example, carbon dioxide (CO2), chlorine, some bacteria are susceptible to destruction, but there are also other undesirable components (potentially harmful) present in water. Thermal treatment does not modify the chemical composition of boiled water, for example with regard to nitrate content, which is very dangerous for infants and young children.

Properties of this type of water for the human body

One can live a week without food, but only 2 or 3 days without water. Water is absolutely essential for the proper functioning of the organism, because it is a basic part of its internal environment.

Water plays an irreplaceable function, since it helps maintain a stable environment in the body, homeostasis. Create the environment for many physical, chemical processes, participates in thermoregulation, waste removal, maintenance of constant body temperature, forms mechanical protection in the brain. It is important for the metabolism of respiratory gases. Water intervenes in almost all organism processes. It is a solvent in which nutrients, minerals, metabolic products and hormones dissolve.

The lack of liquids is manifested by headaches, descent from blood pressure, respiratory disorders and urine color change to a dark yellow. With a reduced contribution of fluids, the organism goes to “conservation mode”, reducing urine excretion, which slows down the removal of waste. Under these conditions, the kidneys are the ones that suffer the most. The prolonged lack of water also affects hair quality, nails, skin status, fatigue, causes concentration problems, urinary calculations, dehydration, deterioration of internal functions and, in the most serious cases, leads todeath.

A drink regime is important for the proper functioning of the human body. It helps maintain a balance between intake and excretion of fluids. Its deficiency is manifested by thirst.

The need for water depends on sex, age, temperature, humidity and physical activity. Possible diseases also influence the necessary intake (especially the increase in fluid loss, for example, vomiting, diarrhea).


The Chinese are known for using hot boiled water as a regular drink. On the contrary, this habit may seem eccentric, abnormal for a European. For us, hot boiled water is part of a drink like tea or coffee, it is not a drink in itself. How can the body of drinking it benefit? Is boiled water good for the human body? Let us inspire a Chinese tradition and let the body relax after drinking a sip of hot water in the cold days.

Doctors do not agree on the temperature of the liquid that is drink. Some believe that ambient or body temperature is better than low. They point out that after drinking cold water, the body spends the energy necessary to heat it to body temperature. On the other hand, some doctors argue that it is important to drink cold liquids after exercise, since they help effectively cool the heated body. For a third group, the temperature does not matter. These experts claim that the most important thing for the body is water, not its temperature.

But the fact is that when cold drinks are consumed, the fats of the food consumed become more solid, therefore less digestible, more difficult to eliminate from the body. When hot liquids are consumed, food fats remain in a liquid state, so they can get out more easily from the body. This allows the body to digest food more quickly, more easily.

Hot boiled water health benefits:

  1. Heats the body in cold days (in addition, unlike coffee or tea, it has no side effects).
  2. Increases the metabolic rate, stimulates the kidneys, the digestive tract, favoring the effective excretion of toxins.
  3. Accelerate the weight loss process.
  4. Reduce the amount of mucus in the nasal cavity, the esophagus and the digestive tract.

Drink hot boiled water and Chinese medicine

It is known that Chinese medicine is based on the balance of two principles: Yin and Yang. According to this philosophy, it is beneficial for the human body to consume water at body temperature. But in case of hypothermia, chills, drowsiness, depression, flatulence, the body is in imbalance; In such cases, it is advisable to drink hot liquid.

Improvement of digestion, intestinal function

Drinking boiled water after eating favors digestion, decomposing food in the stomach. It also eliminates the remains of food that remain in the digestive tract and helps clean the intestines and improve the emptying.

The hot liquid will also eliminate fermentation waste. If lemon is added, it will detoxify the intestines, it will improve its functionality, it will prevent diarrhea and constipation.

Body and mind cleaning

Drinking boiled water tibia several times a week has great detoxifying benefits. Body temperature increases with hot food or liquids. The therapeutic effect consists in activating perspiration, a natural cooling process that further accelerates toxin elimination through the skin (an added advantage is the cleaning of the blood). The elimination of body toxins also improves mental wel l-being.

Drinking hot boiled water is an effective way to treat nasal congestion in allergies and colds. Water vapor dissolves the accumulated mucus in the nasal cavity. It also balances the dehydrating effects of caffeine from other hot drinks (for example, coffee).

Have you boiled water twice in a row? It will be better for you to throw it. It is not suitable for consumption.

The next situation is familiar to most people. You have boiled water for tea. After leaving it for a while, you attend an urgent matter, but a few minutes later you remember that you wanted to enjoy an aromatic drink. Drinking cold tea is a unattractive idea, so they boil water again, thinking they are eliminating more harmful substances, chlorine. This is a mistake.

According to studies that have carried out detailed analysis of the boiled liquid, the harmful substances are not really destroyed, but the prolonged or repeated boiling increases its concentration! This process activates chemical changes harmful to human health.

New compounds

What happens when water is boiled for a prolonged or repeated period? Increase the concentration of the following substances

  1. Arsenic. According to WHO, the greatest threat to drinking water is arsenic, which causes poisoning, digestive problems, diabetes and cardiovascular and cutaneous diseases, including cancer. His undesirable symptoms may take several years to manifest.
  2. NitratesThese substances are present everywhere, including soil, water and air, but they become dangerous when consumed internally, as in the flesh, or when they are exposed to high temperatures. At high temperatures, nitrate becomes nitrosamine, which is carcinogenic. It is especially harmful to ovaries, colon, bladder, pancreas and stomach. The substance can cause leukemia.
  3. The fluorine. Recently many studies on fluoride and its presence in drinking water have been carried out. It is a mineral present naturally in the water, food in lower concentrations. The fresh water contains it in an amount of 0. 01-0. 03 ppm. Its high intake can cause serious health problems. According to a Harvard study, high fluorine concentrations can harm the cognitive development of children. They conclude that fluorine levels in drinking water reduce the intellectual quotient of children. Other investigations have suggested that it can even harm fertility.

Harmful salts

Unhealthy minerals can be harmful. An example is potassium salts, which if they are often ingested can cause the formation of kidney or sand calculations.

Damage to molecular structure

Boiling modifies the structure of water. The duration of high temperatures exposure is proportional to the decrease in liquid utility.

Virus and bacteria

Some pathogenic agents are little sensitive to heat. Among the most resistant are

  • the hepatitis virus (supports 125 ° C);
  • prions (105-125 ° C);
  • Botulinic toxin (100 ° C, but survives at this temperature about 4 hours);
  • Staphylococcus aureus (dies at boiling temperature after about 3 hours).

How to boil water and drink it correctly

According to the Wilderness Medical Society, a temperature of 70 ° C kills most pathogenic organisms (apart from those mentioned in the previous point) in 30 minutes. Temperatures above 85 ° C are killed in minutes.

During boiling (above 95 ° C), pathogens die immediately and water becomes drinkable.

Therefore, the following boiling times for safe consumption are recommended:

  • 30 minutes at 70 ° C;
  • 3 minutes at 85 ° C;
  • immediately at 95-100 ° C.

Some tips to improve tap water quality

  • Let the water drain for 30 seconds before each boil’s filling;
  • Be sure to periodically clean the tap filter, as it catches mechanical impurities in the pipes;
  • Never use hot water from the tap to cook or drink.

Important! Boil does not eliminate the chemical poisons that water can contain. If it is very dirty, you must first strain it with a cloth or other material to remove deposits. A second option is to let it stand and then drain the clearest surface water.

Differences with fresh water

Fresh water contains important salts (trace elements). It favors cell regeneration and counteracts free radicals. The disadvantage is the possible presence of pathogens in it.

The boiling process reduces the percentage of oxygen and salts. This makes the liquid “empty”, less valuable for the body.
