Let's try to clarify the information about water, since not everything about it is true.
💧Water is the main medium for metabolism.
- Without it, metabolism is impossible;
- Without water, you will not lose weight and will not recover even from a common cold;
- The amount of water in the body is an indicator of youth;
- Water is one of the most important participants in the regulation of body temperature;
- Transport for useful, nutrients in the body;
- Even oxygen in erythrocytes is also transported by water;
- It also transports waste, harmful substances and removes them from the body;
- Water humidifies the air coming from outside;
- It creates hydrostatic, that is, water pressure in the vascular system and tissues, again providing metabolic processes.
- And if you do not drink for a long time, then you will remember that it is also very tasty.
💧We are more than half water.
When we are born, it makes up just over 80% of the total body weight.
In average age, men are 60% water and women 50%.
By old age, we completely dry up - we only contain 40-45% of water.
💧 The water in the body is divided into sectors.
2/3, that is, almost 40% of the body weight is contained within our cells. All biochemical processes occur only in water, which is why it is so important.
The rest of the water is divided into 3 sectors -
- the liquid part of the blood, the so-called plasma, that is, the intravascular fluid,
- intercellular fluid, which, in addition to metabolic processes, also acts as a reserve in case of a lack of water in cells or vessels;
- extracellular fluid, which is located inside the joints, in the ducts of the glands, in the spinal canal or in the skull.
Blood plasma and intercellular fluid are very similar in composition to each other. There are minor differences. For example, plasma contains slightly more calcium and potassium, proteinate.
The extracellular fluid contains more sodium, chlorides, and vice versa, there is practically no protein. But the intracellular fluid is fundamentally different from other fluids - it contains more potassium, magnesium, protein, and no organic acids. These differences are not accidental, since, thanks to the gradient, liquid or trace elements can leave the cell, be stored inside, or vice versa enter it.
💧 The largest amount of water comes from outside - from food and drinks. This is the so-called exogenous water. With drinks (juices, tea, coffee, etc., except for water), from 500 to 1700 ml per day is supplied. We get another 800-1000 ml with food and ready-made meals.
The same water that is formed in the body itself, as a result of the oxidation of fats, proteins and carbohydrates, is called endogenous. It can be from 300 to 400 ml per day.
In total, from 1600 to 3100 ml are supplied per day.
💧 How much water is excreted from the body? The kidneys excrete from 1400 to 1800 ml per day on average, another 500-600 ml permeates through the skin. With breathing, we lose an average of 400 to 500 ml of fluid. These are the so-called intangible losses.
It is important to understand, however, that ambient temperature and humidity can change this amount. As well as body temperature. For example, with an increase in body temperature by 1 degree, intangible losses increase by 500 ml per day. This is essential. It turns out that on average we lose from 2300 to 3100 fluids per day.
To feel good, be healthy and live long, you need to strike a balance between how much water came in and how much water came out.
WHO believes that a person needs to drink at least 30 ml per kilogram of weight. That is, a 70-kilogram person needs 2 liters of 100 ml of water per day.
