How Does Drinking Water Affect Your Blood Pressure Levels?

High

blood pressure, or hypertension, happens when the force that your blood exerts on the walls of your arteries and veins becomes higher than it should be. While you can maintain it through medicines and lifestyle changes, one of the most organic ways is to drink water regularly. Since blood is around 90 per cent water, dehydration can reduce your blood volume and lead to the blood vessels becoming narrow, raising blood pressure. And so, you need to be well hydrated with 6 to 8 glasses of water daily to maintain balance.

How does dehydration increase blood pressure?

Doctors say dehydration happens when your body loses more water than it can replace, and that may happen because of excessive sweating, diarrhoea, vomiting, or even too much urination. And so, when you become dehydrated, your body loses electrolytes - those that usually help muscles contract and regulate the movement of fluids in and out of your cells through sodium. Sodium is important for maintaining electrolytes for normal blood pressure. It also supports the contraction and relaxation of muscles - including those in your blood vessels. So, when the sodium levels go low, it triggers the release of vasopressin, a hormone that helps your body hold on to water. And so, high blood pressure can also lead to acute kidney failure, making your body go into shock due to lack of oxygen, ultimately causing organ failure.

How does drinking water normalise blood pressure?
