Scientists have zeroed in on receptors in the liver that govern blood pressure rates in certain kinds of people, especially ill people and elderly people in general, even if they’re healthy.
These receptors, or regulators, are triggered by the simple act of drinking water; in response, the regulator raises the blood pressure by up to 50 points. The amount of water that triggers the response is a half liter, or 17 ounces, consumed at once.
Other people affected by the regulator include drug users and people of any age with nervous-system disorders.
After discovering these receptors, researchers at the Max Delbruck Center for Molecular Medicine, in Berlin, and two other research centers in Germany, were also able to determine, through animal studies, how the receptor could be stopped from working – i.e. prevented from raising blood pressure.
With that knowledge, the researchers say, physicians can give the right amount of water, in the right way, who need it--without worrying about elevated blood pressure.
