How Much Water Should You Drink To Keep Your Heart Healthy?

Table of Contents

Every day, we all have to drink a certain amount of water. But what is the best amount? We are all different and so our needs vary, but most experts recommend drinking half of your weight in ounces of water each day. However, you should be careful not to overhydrate yourself, because that can cause renal failure. So here is a study to keep you well informed on how much water you should drink to keep your heart healthy.

The Study

Sufficient fluid is essential for all bodily functions, including good heart function. So, how much water is needed?

Scientists at the National Heart, Lung, and Blood Institute in the United States have found that serum sodium is an accurate indicator of hydration status. 

For 25 years, they followed 15,000 adults and found that if people drink little liquid, sodium in the blood serum increases. 

The body tries to conserve water and activates processes that increase the risk of heart failure. At the same time, an increase in sodium levels by one mmol / l increases the likelihood of heart failure by 20%.

Scientists also found that the amount of fluid needed varies by gender: women are recommended to drink up to 1.6 to 2.1 liters (6 1/2 to 8 3/4 “8 oz. cups”) of fluid per day, and for men – from 2 to 3 liters (8 1/3 to 12 1/2 “8 oz. cups”). 

Good hydration can reduce the risk of left ventricular hypertrophy and heart failure. 

But, when calculating the daily water balance, one must consider ordinary water and drinks (tea, coffee, juices) and water contained in food (soups, cereals, stews, salads, etc.).


Drinking less than the recommended amount of water per day contributes not only to dehydration but also to dehydration-linked heart failure.

Daily intake of water can help to prevent or at least slow down the changes in your heart that lead to heart failure. Recommendations on fluid intake are different for men and women.

When people don’t drink as much fluid, their status becomes more dehydrated which causes the body to conserve water in other ways that contribute to getting heart failure.
