Staying Hydrated: The Surprising Link Between Drinking Water and Preventing Blood Clots


Does Drinking Water Help Prevent Blood Clots?

Water is an essential component of our daily lives, and our bodies cannot function properly without it. From regulating body temperature to aiding in digestion, water plays a vital role in maintaining our overall health. But does its benefits extend to preventing blood clots? In this article, we will explore the link between drinking water and blood clots and provide you with a comprehensive understanding of this topic.

The Connection between Water and Blood Clots

Before we delve into the question of whether drinking water can help prevent blood clots, let’s first understand what blood clots are and why they occur. Blood clots are clumps of blood that have changed from a liquid to a gel-like state. These clots form when there is an injury or damage to a blood vessel, causing platelets (cell fragments in the blood) and proteins to form a plug to stop bleeding.

While blood clots are essential in preventing excessive bleeding, they can also be dangerous when they form in healthy blood vessels. These clots can block blood flow, leading to stroke, heart attack, and other serious health conditions. Therefore, finding ways to prevent blood clots is crucial for maintaining good health.

Now, let’s get back to our main question – does drinking water help prevent blood clots? The short answer is yes, and here’s why.

The Role of Hydration in Blood Clot Prevention

Our bodies are made up of 60% water, and staying hydrated is vital for various bodily functions, including blood clotting. When we are dehydrated, our blood becomes thicker, making it more prone to clotting. On the other hand, drinking enough water helps to keep our blood thin, reducing the risk of blood clots.

Furthermore, dehydration can also lead to a decrease in blood volume, making blood vessels narrower, and increasing the chances of clots forming. By staying hydrated, we help maintain sufficient blood volume and keep our blood vessels healthy, reducing the risk of clots.

Drinking Water and Circulation

Another crucial factor in blood clot prevention is proper blood circulation. When our blood isn’t circulating efficiently, the chances of clots forming increase. Drinking water helps to improve blood flow by maintaining blood volume and ensuring our blood vessels are not constricted due to dehydration.

Moreover, being well-hydrated also helps to thin our blood, reducing the amount of force needed to pump it through our body. This results in improved circulation and ultimately lowers the risk of blood clots.

The Importance of Maintaining a Healthy Weight

Being overweight or obese can also increase the risk of blood clots. Fat cells release proteins that can cause inflammation and damage to blood vessels, leading to the formation of clots. Drinking water can help with weight management by reducing appetite and promoting satiety, leading to fewer calorie intakes. By keeping a healthy weight, we can lower the risk of blood clots.

How Much Water Should You Drink to Prevent Blood Clots?

While there is no specific amount of water recommended for preventing blood clots, the general rule of thumb is to drink eight glasses of water (8 ounces each) per day. This is equivalent to 2 liters or half a gallon of water. However, it is essential to listen to your body and drink water as per your thirst levels.

In addition to water, you can also consume foods with high water content, such as fruits and vegetables, to ensure you stay adequately hydrated. However, it is crucial to note that drinking excessive amounts of water can lead to dilution of essential electrolytes in our bodies, which can be dangerous for our health. Therefore, it is vital to maintain a balance and not overhydrate.


In conclusion, drinking water can indeed help prevent blood clots by keeping our blood thin and improving circulation. By staying well-hydrated, we can also maintain a healthy weight, reducing the chances of blood clots forming. However, it is not a foolproof method, and factors such as genetics, underlying health conditions, and lifestyle choices also play a significant role in blood clot prevention.
