We all know that the most important elements for people to survive are air, water and food, from this ranking, air is the first demand, no air in a few minutes will suffocate people; Water is the second need, and if you don't have water for a few days, you will die of dehydration; Food is the third need, supported by air and water, even if there is no food, some can withstand dozens of days.
From this, we can see that water is one of the most important elements in human life, and the study of the origin of life believes that life would not exist without water. The normal supply of water to the human body is the most important guarantee for human health. Because water has such an important position in human life, there are many people who make a fuss about the human body to replenish water, and even make the article bigger and bigger, and flicker a large circle of water culture.
As a result, human beings have been drinking water for hundreds of thousands of years, a very natural and simple daily habit, but now they are flickered into dizziness, at a loss, and do not know how to drink water to be healthy. Today we will peel off all kinds of paintings covered in the common sense of drinking water, and drink water to be innocent.
First, understand the body's need for water.
From the appearance point of view, the human body can be divided into head, neck, trunk, limbs, the surface of the body is the skin, the skin is below the subcutaneous tissue, muscles, bones, etc., the inside is the skull cavity maintained by bones and muscles, chest cavity, abdominal cavity, etc., the cavity is distributed in the brain, heart and lungs, gastrointestinal pancreas, spleen, kidney, bladder and other internal organs. These organ tissues seem to be completely different in form, but they are all composed of various cells, so cells are the "bricks" of the human body, and these "bricks" are about 40~60 trillion.
Each cell "brick" has an extremely fine structure and function, but it is composed of various known elements on the earth, of which there are 11 kinds of macroelements, namely oxygen, hydrogen, calcium, sodium, carbon, phosphorus, chlorine, sulfur, magnesium, nitrogen, potassium, etc., in addition, there are more than 40 kinds of elements that can be found in the human body, but the proportion does not exceed 0.05%. Among the 11 macroelements, 4 of them, namely oxygen, calcium, sodium and carbon, account for more than 95%.
The substance that makes up the most of the body is water. According to age and different groups of people, the proportion of water in the human body is about 45~75%, so the average water content of the human body is about 70%. These waters flow in human blood, various organs and cells, are the most important conduction medium of nutrition and metabolism of the body, and regulate body temperature through the circulation of body fluid exchange, lubrication and maintenance of the normal function of various organs, bones, joints and muscles.
That is to say, a normal adult weighing about 60 kilograms contains 42 kilograms of water in the body, and in this sense, people survive by water nourishment. Of course, this water does not suddenly enter the human body one day, but slowly accumulates as the body grows from the beginning of conception.
In life activities, the human body consumes about 2500 ml of water per day, which is mainly lost through the following channels: excretion of metabolic waste in the human body through urine, about 1400ml per day; oxygen exchange through lung breathing, loss of water by about 500ml per day; Stool excretion needs to be moistened to take away about 100ml of water; Skin breathing loss of moisture about 350~700ml.
This is just a general situation, such as in a large amount of exercise or physical activity in a higher temperature environment, water loss is difficult to say, sometimes it may be up to 2500ml of water loss an hour.
From the perspective of the body's demand for water, a person in the ordinary normal state, daily water replenishment of about 2500ml can be, of course, in the exercise or high temperature, heavy physical activity environment, water loss is large, it is another matter, need to be timely and reasonable water replenishment according to the actual situation.
How to rehydrate, and how much water does a person actually need to replenish per day?
I don't know that once upon a time, the problem of drinking water has attracted more and more attention from some "masters", and various ways to drink water are blowing more and more mysteriously, what to drink 8 glasses of water a day, to drink a large glass of water in the morning, it is best to drink mineral water, weak alkaline water, and what large molecular water small molecule water and so on.
In fact, these are all, are all big flickers, the purpose of flickering is to make money, some inexplicable water is more and more, and the price is getting more and more expensive.
In fact, water is water, is H2O molecular formula composed of water, the human body needs this ordinary water, any water that adds branches and leaves to the name of water will not only bring health benefits, but also may bring harm.
First, let's look at how much water an adult needs to replenish each day. As mentioned earlier, a normal person loses about 2500ml of water per day, so as long as you supplement 2500ml, you can get balanced. How can this water be replenished? Generally speaking, people only need to drink 1000~1500ml of water directly every day, and the rest of the water can be ingested from food about 1000ml, and the endogenous water produced by the body's own metabolism returns to the circulation of about 300ml.
Secondly, the water needed by the human body is H2O, and there is no need for weak alkaline water or mineral water. According to the function and role of water in the human body, what is needed is ordinary water, not weak alkaline water or mineral water. Of course, some water contains some trace elements that are beneficial to the human body, and there is no harm, but the trace elements of the human body are mainly supplemented from food, and eating vegetables and fruit foods casually contains more trace elements than in water.
In some special cases, such as high temperature environment or sports, heavy physical strength and other activities, sweating drainage is large, need to be supplemented in an orderly manner according to the amount of drainage, at this time do not irrigate, drink a large amount of water together, resulting in electrolyte imbalance in the body, disorder, this is the so-called water poisoning, serious will be life-threatening.
This is a complex problem, it is not clear at once, in short, drink water do not drink at once, do not wait until thirsty to drink, do take the initiative to drink water, a small amount of many times, timely supplementation. Do these things, you can drink water healthily. If excessive water intake or lack of water leads to electrolyte imbalance in the body, tachycardia, irregular heart rhythm, numbness of limbs, hypotension, confusion and other symptoms, seek medical attention immediately and in time.
So, what is the best water to drink?
In fact, it is very simple, that is, drinking boiled water or pure water, mineral water is healthy water, as long as the water quality is up to standard, it is healthy water. The so-called water quality standard means that the microbial indicators, toxicological indicators, chemical indicators, radioactivity indicators, etc. in the water need to meet the national standards. This standard is very complicated, I will not introduce them here, but there is a point, that is, the tap water transported by the country's formal enterprises must meet the standard.
Therefore, to drink water at least drink tap water supplied by national formal enterprises, try not to drink those self-used well water, river water, and even the so-called "mountain spring water", because what is in these waters, whether there are heavy metals and toxic substances do not know at all, they think they are "health", in fact, ignorant and self-harm.
Resolutely put an end to the habit of drinking raw water (directly taken from natural cold water), be sure to drink boiled water or qualified filtered distilled mineral water or pure water, these waters can remove harmful microorganisms and harmful substances, to ensure healthy drinking. Although tap water that meets national standards is disinfected and treated, the water leaving the factory meets drinking water standards, but because it is transported through water pipes, pollution such as dirt and rust may be hidden inside the water pipes, so it must also be boiled before drinking.
There is a lot of publicity about drinking water, but one thing I think is still reliable, that is, household water treatment equipment. Due to the various safety hazards and pollution of tap water in the transportation process, even if boiling and drinking it has little impact on health, the taste is always bad and often has a strange taste. Through some water treatment device filtration, some pollutants and harmful substances can be filtered out, the water becomes soft water, the kettle does not scale, the water becomes sweet and delicious, and cooking with this water tastes better.
What water treatment device is good? There will be no advertising here, my opinion is to compare more, buy products with high credibility of big brands, basically can ensure the safety of drinking water.
