Water is the most abundant component that exists throughout the earth’s surface and comes from the Latin aqua. This is a substance whose molecules are composed of one oxygen atom and two hydrogen. Water is an insipid, odorless and colorless liquid that is present in different states and that we can find distributed in different natural elements.
For example, the gaseous state is the vapor found in the atmosphere, the solid state is about lakes and rivers that freeze and turn into ice, and the liquid state is made up of oceans, streams and rivers. If we talk about percentages, we can mention that 70% of the earth’s surface is covered with liquid water and around 96% corresponds to salt water. On the other hand, about 69% of the remaining 30% is frozen water from the poles and between 1% and 4% is made up of water vapor in the atmosphere.
The definition of this substance can be used with any form in which it is presented, however, there are some types that are categorized by their biological, chemical or physical characteristics.
- Raw: this is the one that has not received any treatment and can be found in natural reserves and sources.
- Gray: these are the ones that come from domestic use
- Black: contaminated with urine and feces.
- Wastewater: When we talk about wastewater, we mean anyone that has been negatively affected by humans.
- Distilled: purified through distillation
- Soft: A small amount of salts is dissolved in this substance
- Hard: Contains large amounts of dissolved minerals
- Drinking: we consume it daily
- Sweet: we can find it on the earth’s surface and in underground ecosystems
- Salty: contains 35% of dissolved mineral salts
- Brackish: it has more salts than sweet

10 facts you surely did not know
Through the book “Clearer than water”, Dr. Magda Carlas defines some nutritional properties that it contains, in addition, she reveals some very interesting data that some people do not know about the importance of hydration in physical performance and how it helps with obesity and stress. Next, these are the 10 most interesting facts that we have been able to highlight.
How much water do you need to drink daily?
The answer to this question will depend entirely on factors such as where you live, if it is wet or dry and also if you do sports or not. However, the author of this book recommends following the guidelines of the European Food Safety Agency which indicates that men should drink a total of 2.5 liters while women 2 liters adding drinks and meals.
Drink water, even if your body doesn’t ask you to
Many people think that if the body does not ask for liquid, it is not necessary to drink it, but this idea is completely wrong because when thirst appears this means that approximately 1% of body water has been lost and for this reason they begin to become visible some effects such as decreased performance, lack of concentration, fatigue, among others.
If I drink water between meals, do I get fat?
Something that must be made clear is that this substance cannot make you fat because it does not contain calories. However, with regard to whether or not we should drink it with meals, the answer according to Carla is that yes, she even recommends always having a glass of it to drink during the meal. On the other hand, there are people who say that water during the meal delays the feeling of fullness, but Carla clarifies that this is the opposite because by doing this, the size of the bolus is increased.
Does sparkling water make you fat?
The answer is a resounding no, but what it can do is occupy a volume and manifest itself in your body in the form of swelling, but this will depend on the amount of sparkling liquid you have drunk.
When you are on a diet
When we decide to start a diet, it is advisable to drink water because with weight loss there is an increase in the body’s catabolism and it begins to eliminate substances through the kidney. In addition, this substance has the ability to increase the feeling of fullness because it occupies a place inside the stomach.
What should I drink when I exercise?
According to Carla, after 30 minutes of exercise it is advisable to rehydrate. A suggestion for an intense exercise of 150-250 cc of liquid every 20 minutes. In addition, it is important that the water temperature is 10-15 degrees so that it has a greater rehydration power.
Tap or mineral
If what you want is to quench your thirst, Carla recommends tap water because it has few minerals, on the other hand, natural mineral water has a mineral composition that is detailed on the labels.
Carla assures that: “The lack of minerals is a characteristic and not a virtue.” This can be the best option for some types of heart or kidney diseases and they are also used to make bottles for babies.
The condition of the skin
The hydration of the skin, the best functioning of the body’s organs and many more depend on the amount of water we ingest. A clear example of this is that dry eyes and vaginal dryness are closely related to low water intake. Even bad breath also has a lot to do with this because dry mouth could be synonymous with halitosis.
The older you are, the more water you should drink
This is completely true because water will help keep kidney function in excellent condition, but the problem is that the older you get, the less thirsty you feel. For this reason, many older people are unnecessarily dehydrated.
