THE DISCOVERY OF WATER

I must point out the following article from the September 16 n.37 ESPRESSO written by Tiziana Moriconi:

If you feel sleepy and the pressure under your shoes, forget about the energy drink: the real refreshing drink is water, without adding sugar or other. According to the findings by researchers at Vanderbilt University Medical Center (Tennessee, USA), a few glasses are enough to raise blood pressure and the state of happiness, and even promote weight loss. The water it increases the activity sympathetic nervous system and, consequently, energy expenditure. Also works as a vasoconstrictor, also prevents blood from pooling in the extremities of the body.

Julia McHugh, also of Vanderbilt University School of Medicine, has found out later where and how you experience this physiological effect. According to the results of the study, published in "Hypertension", the mechanism will be established in the stomach or first part of the intestine (duodenum), because the pressure increases even though the water is introduced directly into these two organs.
not seem to have any role, in addition, the dissolved salts, since the pressure does not change if we comministrano only minerals. Indeed, early data indicate that the effect may be using more water low in salts.
The effect was well observed in patients with barosferiflesso system (the geese keep the values \u200b\u200bwithin the normal range) damaged. In young and healthy, however, the pressure changes are much more modest, the fact remains that black pint of water before donating blood reduces by 20 per cent of the fainting, as demonstrated by a study by the American Red Cross.
