Can Drinking Lots Of Water Lower Blood Pressure?

Water combines with various other substances present in the bloodstream of a person to play a significant role to maintain the levels of blood pressure and hydration.

Blood Pressure and Water Intake

Blood pressure of people varies during the daytime and may go down or up depending on their mental and physical states. Doctors consider blood pressure, as measured consistently higher than 140 mmHg (millimeters of mercury) systolic or more than 90 mmHg diastolic as high pressure.

Eating food items and various liquids containing high amount of salt will contribute to raise the problem of blood pressure. In addition, by consuming fluids or water in inadequate amount leads to dehydration and high levels of sodium in the blood stream of a person.

Can Drinking Lots Of Water Lower Blood Pressure?

Yes, drinking lots of water will help in lowering your blood pressure. Whenever any person intakes water in inadequate amount, the patient’s body compensates via retention of sodium. Indeed, this is a red flag, as sodium has close relationship with the problem of high blood pressure.

With the retention of sodium, persistent dehydration results in gradual closing of various capillary beds present in the human body. This results in increase in pressure on arteries and thereby, causes increase in blood pressure. Hence, it is essential for you to take the following important steps to avoid the problem of high blood pressure, which may cause dehydration.

Drink about Eight or Ten Glasses of 8-Ounce Water Daily

If you are already a patient of high blood pressure, you should aim to have higher water intake i.e. about eight or ten glasses of water of about 8-ounces on a daily basis.

Let Your Body to Adapt Higher Water Intake

You may to go overboard on your water intake, while your body may only take in adequate amounts. If you fail to have excessive amount of water currently, you have to increase your water intake gradually and thereby, allow your body to adapt it easily. This is because; despite, drinking more amount of water reduces your high blood pressure problem, drinking higher than 96 ounces water daily may create increase stress on your kidneys and the digestive system.

Drink Water Before Your Physical Exercise

You should make sure to replenish the water store, which you lost while doing exercises via evaporation and sweat. You should make sure to intake water in sufficient amount before, at the time and after completing your physical exercise. Especially, when you do physical exercises, you should always keep the following points in your mind-

  • Drink about 2 glasses i.e., 16 ounces of water or fluid before two hours of your physical exercise.
  • Drink water for every 15 minutes while you involve in any physical exercise session lasting for about one hour.
  • You should strictly avoid restriction fluids while you do exercises, if you work to reduce your blood pressure levels.


Body a human being consistently seeks for balance and gives responses to changing sodium levels and other electrolytes present in the blood stream by simply increasing or decreasing its blood volume. Whenever the levels of sodium in your blood increases too much, your kidneys give responses by exerting excessive amount of sodium in combination with water as urine.

If you are already a patient of kidney or any other related systemic problem, which your body fails to cope up and burden under a huge load of sodium, your blood pressure will increase. Drinking of water in higher amounts increase the amount of water or fluid in the body to reduce the load of sodium (based on excretion of sodium) and maintain pressure in blood vessels.
