A new research report has revealed that water doesn’t really satisfy the urge for thirst, it rather manipulates the blood pressure, making it moderate.

Lead researcher, David Robertson, and his team Vanderbilt University Medical Center identified the quality nearly a decade ago, in those patients who suffered a loss in their baroreflexes, the mechanism regulating the blood pressure within a normal ratio.

Water elevates the compassionate battle or flight movement in the nervous system, which enhances alertness, blood pressure and energy spending.

The American Red Cross observed that intake of 16 ounces of water ahead of blood donation, turns down the fainting likelihood by 20%.

As it has been claimed that water increases sensitive nervous system activity and the subsequent energy spending, however, it does encourages weight loss, Robertson said.

The study appeared in June issue of the journal Hypertension.

"The observation came as a complete surprise. We had to unlearn the idea that water had no effect on blood pressure”, said Robertson.

The current study found that water reaching the stomach or duodenum directly, increases blood pressure, which excludes an oral or esophageal mechanism for the response.
