12 Myths and Facts About Water That Will Surprise You
Water is the basis of life not only for man but for our entire planet. It is the main component of living organisms. It would seem that we all know about water, about its properties and benefits. But the process of cognition does not stop, and science opens up new facts.
Unfortunately, along with scientific evidence, there are a number of misconceptions and fabrications that are firmly rooted in our heads. Let’s see what is a myth and what is a fact.
12 Myths and Facts About Water
How much to drink water?
1. A person should drink 8 glasses of water per day
This is a myth. It is not clear where this norm came from. Yes, it doesn’t matter. The fact is that people with different weights and different muscle masses need different amounts of water. Usually, it is recommended to proceed from an average indicator of need: 30-40 ml per kilogram of weight. But these indicators are not accurate. The daily rate directly depends on the climate, age, characteristics of work, chronic diseases. If you play sports or work is associated with physical activity – they need for fluid increases.
However, do not forget that most of this water is found in the foods you consume. Back in 2007, BMJ magazine included an item on eight glasses of water per day in the list of major medical myths of our time.
2. Water leaches toxins from the body
This is a fact. The normal activity of the kidneys is provided by the use of a sufficient amount of clean water. As you know, the kidneys are a natural filter of the body, and water helps to eliminate toxins from the body, and mainly through the kidneys.
3. If you have swelling, drink less water
This is a myth. If edema is not associated with serious diseases, then just the opposite. If there is not enough water in the body, it begins to stock up for the future. Especially if you regularly drink a little water. As soon as you start drinking enough water, everything will return to normal, the body will cease to make supplies.
4. Water helps the skin to be hydrated
This is a myth. It is believed that the main factor that plays a role in the state of skin hydration is a large amount of water consumed. Of course, if the body is very dehydrated, then this will worsen the condition of the body as a whole. But water does not reach the epidermis (upper layer of the skin). If you are healthy, then the skin condition depends on external factors. This is both the environment and proper skincare. The amount of sebaceous glands and their functioning also affects our dry skin.
5. Drinking water will help reduce weight.
This is a fact. More precisely, water helps in this process. It should be noted that we are talking about clean drinking water, and not about carbonated drinks. Water speeds up the metabolism and reduces appetite, or rather the thirst that we often take for it. The areas of the brain that control these two sensations are nearby, so we are often confused.
6. Yellow urine is a sign of dehydration
This is a myth. The normal color of urine is considered to be dark yellow transparent, light yellow transparent, and yellow transparent. Many factors determine the color of urine. This is taking medications, some food colors, laxatives, disruption of the body. With dehydration, the color of the urine changes of course. The color becomes dark amber. This indicates an increase in the concentration of nitrogen and urochrome slags.
7. If you are thirsty, you are dehydrated
This is a myth. Thirst does not mean that you are dehydrated. Thirst is a signal from our body that it needs more water. There is a certain amount of salt and water in our blood. Thirst is the result of an increase in the amount of salt compared to water. If the salt concentration has increased by 2 percent, you are thirsty. If 5 percent or more, you will start dehydration.
8. During sports, you need sports drinks, not water
This is a myth. Sports drinks have good advertising, but not everyone needs them. Sports drinks contain electrolytes, which are necessary for the proper functioning of body cells. Perhaps, people who participate in long marathons or whose training lasts a long time, they will benefit, but for most people they are useless. In addition, many drinks contain only water and sugar, and trainers advise to refrain from drinking them. Pure water is all you need during your workout.
Interesting facts about water
9. You can drink a lot of water
It is a fact. Of course, people with certain diseases can put their health at risk by drinking too much water. These are some heart diseases, high blood pressure, swelling of the lower extremities, kidney disease (transplant). In this case, they should consult with your doctor. In other cases, you can drink water as much as you want. Because if you consume a little water, then the kidneys are forced to produce more concentrated urine, which can provoke the formation of kidney stones.
10. Do not use a plastic bottle again
This is a fact. Using a disposable water bottle a second time puts you at risk. Even refillable bottles (made of polyethylene and polypropylene) are relatively safe if they are constantly decontaminated. Well, who will do this? Plastic bottles are a suitable medium for the growth of bacteria. The level of bacteria in such bottles often exceeds acceptable standards. Use reusable wide-necked water containers that can be washed well. You can use disposable drinking tubes.
11. The existence of a “memory” of water is not scientifically proven
This is a fact. At all times, people endowed water with magical properties. Everyone knows the legends of “living” and “dead” water. People want to believe in miracles. They started talking about water in order to endow it with healing properties. But, this is just a popular belief. Physicists firmly say structured water is an unscientific fiction. There is no scientific evidence to prove the existence of a “memory” of water.
12. Do not boil boiled water repeatedly
This is a myth. Among the people, there is a horror story that supposedly you can’t boil water again. From this, the crystal lattice is broken and the water becomes “heavy”. The fact is that such water really becomes “heavy”, since the content of heavy hydrogen isotopes, deuterium, increases in it. And it is dangerous to health. Here, experts do not argue. But the concentration of deuterium in boiled water is so small that you should not be scared. There is no evidence in medicine that such water can be harmful.
Of course, water is not only a source of health but also a source of disease, since it dissolves toxic substances well and is a carrier of pathogenic bacteria. Use only clean water and be healthy.
