Elders hydrate less than young adults, both in Europe and in the United States.UU.

the next Congress of the European Federation of societies of nutrition (FENS) addressed in Madrid in monographic form Symposium hydration: a key aspect of nutrition ”

-En EE.UU. the population is more than hydrates in Europe

-lack of hydration can cause alterations in energy efficiency work, degree of attention and performance of the worker

-experts recommend rehydrated every hour during the working day with water and non-alcoholic beverages

Madrid, and October of 2011- the eleventh Conference of the European Federation of societies of nutritionwhich will take place in Madrid from 26 to 29 October, it will address in a monographic manner at the Symposium hydration: a key aspect of nutrition ”, novel aspects about the importance of hydration, as the guidelines and recommendations of fluids according to the type of work performed and the environment in which to develop, or the status of Spain fluids of the population relative to other countries.

According to Patricia Padrao, belonging to the Faculty of food science and nutrition from the University of Porto (Portugal), and one of the speakers will participate in the Symposium, the Americans are the population more total water consumption makes on a daily basis (between 2.84 L/day and 3.91 L per day average)followed by Canadians (2.41 L every 3.04 L/day), while in Europe the values are considerably lower (between the 1.98 L/day in France to the 2.62 L/day in Holland), while complying with general recommendations. According to the specialist, men do a greater total water consumption than women, both in the countries of the continent and in the United States.UU.

In Europe, and according to the data relating to total intake of drinks ” there are apparently large differences with regard to the consumption of liquids from a village to another, together with methodological variations among national opinion polls. In particular, Italy seems to be the country with one lesser intake (about 1 l day) while Spain presents values higher (up to almost 2 liters/day) in adults, theoretically superior to United Kingdom, Belgium and Portugal.

In the third age, the average daily intake is lower for young adults, both in North America (2.14 L/day to 2.99 L/day) and in Europe (of 1.61 L every 2.24 L/day), being the stage of life with higher percentage of people do not reach the values of reference (in some countries)(, until the half of the population within that stage).

Hydration in the workplace and their patterns

Another key element that has not received sufficient attention so far is the need to maintain adequate hydration in the workplace, which must adapt to the needs of individual, characteristic of labour and environment where it takes place. A work of media physical intensity and a little warm environment, recommends drinking at least one glass of water or liquid every hour. According to Prof. Dr. Lluis Serra Majem, Chairman of the foundation of research of nutrition (FIN) and another of the speakers who will participate in the Conference, for a same temperature of 35 ° C, a sedentary job can cause a loss of fluids through sweating of approximately five litres while one intense could get to about 16 liters a day ”.

For this expert, the lack of hydration can cause alterations in the efficiency at work, degree of attention and, above all, on the health of the worker. Dehydration increases the effort cardiovascular increasing 4 beats to the minute per each percent of body weight lost, which leads to an increase in the perception of fatigue, and in a dehydrated worker, can alter their labor productivity. Various studies have shown that when dehydration exceeds 2% of body weight, performance and working capacity decrease and even more if you are working with heat.

To promote a greater awareness in this field in the health professionals, responsible for companies and authorities, has developed a guide that presents the latest knowledge in the field of hydration and occupational health that will be addressed during the Symposium. Is highly recommended to promote breaks during the work, although in many cases companies think that it is a waste of time and productivity. In fact more likely that maintaining hydration maintained enough productivity to compensate for the breaks, especially in hot environments, with air conditioning or a large burden of work both physical and intellectual ”, points out Serra Majem.

Strategies in fluids for higher sports performance

In specific situations such as the practice of sports, the importance of adequate hydration is if it can be even greater. For Prof. Dr. Ron Maughan of the school of sport, exercise and Sciences of the health of Loughborough University in United Kingdom and one of the experts that will also pass through the Symposium on hydration, a few simple tips can help the athlete to assess its state of hydration and develop a strategy customized according to the Office to carry outthe environment and individual needs. An appropriate strategy will consider hydration status prior to the exercise as well as the need for fluids, electrolytes and energy before, during and after the ”. The needs of carbohydrates will also vary and drinks should contain variety of sugars to maximize absorption and oxidation.

Finally, the assistance of Maxime e. Buyckx, Health and Wellness Programmes is planned. Global Scientific and Regulatory Affairs. Coca-Cola. Atlanta (USA).(UU.), which will feature the work being carried out by the ILSI International Institute created in 2001 to provide scientific knowledge on hydration, addressing the conclusions of some of his work more relevant.
