Drinking Water's Impact on Blood Pressure: A Health Overview
High blood pressure is when blood pushes too hard against your arteries.
Drinking enough water is like giving your body a helping hand.
Water makes up most of your blood, and when you're low on water, your blood pressure can go up.
Drinking 6 to 8 glasses of water daily can help keep your blood pressure normal.
Dehydration can cause the blood vessels to narrow and also causes your body to lose electrolytes, which causes vasopressin levels to rise.
Drinking beet juice, tomato juice, pomegranate juice, and low-fat milk can also help maintain healthy blood pressure.
