Water is the main component of the human body, an essential nutrient involved in all the fundamental functions of the organism: without water there would be no life. Our well-being is closely linked to water, but despite being one of the simplest and most accessible elements, its health role is too often overlooked. Drinking an adequate amount of water every day is one of the easiest exercises to keep fit.
Attention to the media and the scientific world
Media attention on the topic of water is growing to scientifically deepen the role it plays in promoting good health. From the recent researches emerge the relationships that exist between the water and the functioning of different organs and systems of our body. Unusual themes such as the analysis of the effects of water on the mind and on cognitive states become more and more the object of study.
Water and diet
Nutritionists pay more and more attention to the issue of water intake with diet. In fact, water is an essential food that has a primary and irreplaceable role in the hydration of the organism, contributing to the maintenance of the state of well-being.
It is now widely recognized that the role of water also covers the contribution of useful substances, thanks to its high bioavailability, ie the quantity of elements present in it that are assimilated by the body, first of all calcium. Mineral waters containing at least 300 milligrams of calcium per liter and low sodium should be considered as a real food source of calcium that contributes to maintaining optimal bone health.
The myth that calcium-rich waters favor kidney stones must be debunked: there are numerous studies that have shown that a high calcium intake is not accompanied by an increased risk of kidney stones.
The mind is bright if it is hydrated
Considering that our brain is made up of 85% of water it is easy to understand how the pursuit of an optimal water balance is essential for the proper functioning of this vital organ. In fact, thanks to its liquid content, the brain amplifies its electrical conductivity and allows electric currents (through which the connections between the various brain areas and between these and the rest of the body occur) to propagate at high speed and in a manner fluid and continuous. Numerous scientific studies have shown the existence of a direct correlation between the degree of dehydration and levels of cerebral efficiency and intellectual performance. The first signs already arrive at values of dehydration around 2%, with the onset of headaches, a sense of tiredness, initial impairment of attention and concentration, reduction of capacity and accuracy in carrying out tasks, even simple.
Drink more than benefits?
Water helps to lose weight, cleanses the body of toxins, improves the appearance of the skin, helps to digest more easily, also there is a theory that claims that drinking makes us feel satisfied faster, thus taking in less calories. A 2010 study by the Department of Human Nutrition, Food and Exercise in Virginia confirmed this connection, showing that consumption of water significantly reduces calorie intake among middle-aged adults and the elderly.
