Water is an amazing element, without which the human body will simply die. Scientists have proven that without food a person can live about 40 days, but without water only 5. What is the effect of water on the human body?
The structure and main functions of water
By definition, from school literature, water is a colorless liquid that has no smell or taste. It consists of two hydrogen molecules and one oxygen, connected by a hydrogen bond.
Water is the foundation of all life. In the human body, thanks to the fluid, all metabolic processes occur. A sufficient amount of water makes the human body healthy, full of strength and energy.
The main functions of the fluid include:
- Metabolism. Water is the main solvent and the basis of many chemical reactions. Liquid may form as an end result.
- Transportation. Water transports molecules between cells and in the intracellular space.
- Thermoregulation. So that the human body does not die at high temperatures, the water begins to evaporate, thereby cooling the body. Liquid evenly distributes temperature throughout the body.
- Excretion. Water helps to remove the end products of metabolism from the body.
- Fluid is one of the main components of lubricating secretions, juices and body secrets.
It is important to remember that without the required amount of liquid it is impossible to maintain a normal water-electrolyte balance. The influence of drinking water on the human body is invaluable, so it takes part in all processes of human life.
The necessary amount of fluid in the body
The condition of the body directly depends on the amount of water in the body and the age of the person. Thus, dehydration leads to a decrease in fluid absorption, for an adult, the water shortage is equal to a third of the total volume in the body, and for children - a fifth. A vivid example of an insufficient amount of water is an elderly person. You may notice that his appearance changes, his skin becomes flabby and less elastic.
The percentage of water in the body for a child is 80%, for an adult man - 60%, for a woman - 65%, and for an elderly person - 45%.
Based on this, daily it is necessary to drink 2-2.5 liters of fluid. This amount does not include tea, coffee, juices, sugary and alcoholic drinks. The daily norm of water for an adult should not exceed 40 ml / kg, and for a child 120-150 ml / kg.
The positive effect of water on the human body has already been proved by many scientists, so in no case should dehydration be allowed.
Useful properties of water
The state of health and longevity of a person depends on the amount of fluid in the body. What is the effect of water on the human body? Highlight such main advantages:
- It cleanses the body of harmful substances and toxins. That is why during the treatment of infectious diseases, it is so useful to drink a large amount of water.
- The liquid restores youthfulness to the skin, nourishes it and makes it smooth, supple. With dehydration, on the contrary, it begins to peel off and dry.
- Water helps to normalize the digestive tract, prevent constipation. Due to a lack of fluid, a person can feel abdominal pain and develops bad breath.
- Water reduces the likelihood of cardiovascular disease. According to scientists, people who drink enough fluid are 40% less susceptible to heart and vascular disease.
- Water transports the necessary elements throughout the body.
- Drinking the right amount of fluid can start the immune system and prevent many viral diseases.
- With the help of fluids, people improve metabolism and begin to lose extra pounds.
Of course, you should not abuse the intake of water, just stick to the norms calculated for your weight and drink it every day.
The negative effects of water on the body
Water will be useful only if it does not include a variety of chemical elements, harmful substances or bacteria. Therefore, before starting use, it is necessary to study the composition or independently prepare melt water.
The positive effect of water on the human body has been repeatedly demonstrated by many scientists. But what will be the results if you use "bad" water? This is not described so often. So:
- Uncontrolled daily consumption of large amounts of water can lead to kidney and cardiovascular diseases. To prevent this, you need to adhere to some rules while increasing the amount of fluid consumed.
- You should not drink a liter or more of water at a time. In this case, an extra burden on the kidneys is created and the water-salt balance is disturbed.
- Do not drink cold water. So it lowers body temperature, which can lead to sad consequences. Even in the summer season, it is recommended to use warm water.
- Do not exceed the daily rate, which is 40 ml per 1 kg of mass, especially do not abuse fluids before bedtime. This can cause swelling.
If a person still decided to exceed the daily norm, then it is necessary to do this gradually, adding no more than 100 ml per day.
Drinking water quality
Water is one of the main products consumed daily, and not many people consider the effect of water quality on the human body. There are four basic water requirements:
- epidemic indicators within normal limits (microbiological, parasitic);
- harmless chemical composition;
- acceptable organoleptic characteristics (smell, taste, level of chlorides and sulfates, etc.);
- lack of radiation component.
To drink really high-quality water, you must carefully choose the place of its production. Since not every spring water meets the standards. The source of surface water is the nearest water bodies.
The best water for drinking is in artesian springs, the depth of which is at least 100 m. Such a liquid meets all standards and is safe for people.
You will not find absolutely pure water in nature. And there is one in which the level of calcium and magnesium is too high. What is the effect of water hardness on the human body?
Hard water has a bitter taste and negatively affects the digestive tract. Salts of trace elements combine with animal protein, which comes from food, and settle on the walls of the stomach and intestines. Thus disrupting their functioning, causing dysbiosis and poisoning the body. The constant use of hard water can lead to joint diseases and the formation of kidney stones, gall bladder.
Mineral water intake
Mineral water is usually divided into three types - enriched with oxygen, with a high content of silver and iodine.
Most often on the shelves of the supermarket you can find mineral water enriched with oxygen. It is used to treat bronchopulmonary diseases. In addition, it is used for preventive purposes.
Less popular, but no less useful is mineral water with a high silver content. It is an excellent liquid for combating harmful microorganisms. A distinctive feature of this water is its long-term storage.
High iodine mineral water intake is recommended for people with thyroid disease.
The positive effect of mineral water on the human body is increasingly proved by scientists from around the world. So with its help it is possible to cure diseases of the genitourinary system, gastrointestinal tract, diabetes mellitus and kidney disease.
However, it is worth remembering that the abuse of mineral water, instead of improving health, can lead to the appearance of new diseases and a deterioration in the general condition.
Drinking Carbonated Drinks
Sparkling water is a popular drink especially during hot weather. Such a liquid contains useful trace elements and prevents infection by dangerous organisms.
In addition to the positive effect of sparkling water on the human body, scientists note a negative one. So the constant use of such drinks containing carbonic acid irritates the mucous membrane, and carbon dioxide in turn stretches the walls of the stomach.
Melt water
The first studies of melt water began about 10 years ago. And the results are staggering. So scientists come to the conclusion that only meltwater is ideally suited for its structure and characteristics to the human body.
What is the effect of melt water on the human body? The use of such a liquid is the key to pure blood, which activates the immune system, regulates metabolism, cleanses blood vessels and lowers cholesterol.
To achieve the desired results, you must daily drink a glass of melt water. To do this, the liquid is poured into a container and placed in a freezer. It is recommended at this moment to think in a positive way or to say a prayer. In this way, the water will charge positively and bring more health to every cell in the body.
Water is the most important component of all living things. Therefore, it is on its quality that the state of health of each person depends. It should be careful about the sources of life-giving moisture.
