We often take for granted that which is closest to us, that which is essential for our survival. An example of this is water, that liquid gold. Water is excellent at hydrating our bodies; therefore, it is essential for our skin health.
According to the Spanish Academy of Dermatology and Venereology, 30 % of our skin is made up of water, so water intake is essential to maintain skin turgor and elasticity. Dehydrated skin is less elastic; this means it takes longer to return to it original place when we stretch it.
The body mainly loses water through the kidneys in the form of urine and through the skin as sweat. An adequate amount of water inside the body prevents the skin from becoming dehydrated. Without this daily dose, our skin is unable to fulfil its functions as a natural barrier and becomes less smooth. On the outside, water cleans us, calms us and refreshes us.
In order for our skin to benefit from water’s properties, both inside and out, we need to drink a sufficient amount and apply moisturising formulas that penetrate inside our cells. If we follow these two basic pieces of advice, our skin will look healthy and full of life.
The World health Organization (WHO) recommends consuming between 2 and 3 litres, or between 10 and 15 glasses of water a day (1 glass of water is equivalent to 200 ml). 20–30% of this amount comes from solid food, and 70–80% comes from the direct intake of water, according to data from the Spanish Water and Health Research Institute.
The necessary amount of water is not the same throughout a person’s lifetime; rather, it increases with age and varies according to diet, environmental conditions and our level of physical activity, among other factors. As we age, there is a greater tendency to become dehydrated, so we need to drink more.http://www.europeanhydrationinstitute.org/es/hydration_levels.html
The Spanish Heart foundation advises that when exercising, we start drinking water an hour or two before we begin, that we drink before we feel thirsty, that we take a break every 20 minutes to drink water and that we consume drinks containing mineral salts if the temperature is above 25ºC. With a 1% loss of total body water, we begin to feel thirsty; a 2% reduction in body water has been shown to reduce performance and mental function. Thirst, then, is the first sign of dehydration.
In light of all this, we can see that water has great power over us: it hydrates us, calms us, cleans us and assists in the proper functioning of our bodies. Therefore, if we want to feel good and have a healthy, elastic face, we mustn't forget the importance of being properly hydrated.
