One may ask why us talk of sodium in this article, you should know that when you are dehydrated, the water volumes in your body simply go down, this increasing the sodium levels which in turn causes your body to secrete a hormone that is called “Vasopressin” that prevents the kidneys from releasing water in urine and thereby preventing water loss.

The vasopressin hormone released by the kidneys to prevent water loss in urine causes the constriction which in simple terms is the narrowing of the blood vessels and this thereby increasing blood pressure.

Some studies have proved this for example, the animal studies that was conducted by the Monash University reported that chronic dehydration not only worsens high blood pressure in mice but also creates a greater risk of severe kidney damage.

What Volumes Of Water Should I Drink A Day ?

Drinking the recommended volumes of water, a day has many benefits health wise, including:

Daily water intake helps to normalize blood pressure
