The One Thing to Do Every Day to Support Healthy Blood Flow
September 12, 2025
You probably don’t give much thought to your blood flow – until something feels off. Maybe you notice tingling in your hands or feet, you’re unusually tired, or your brain feels foggy. What you may not realize is that your circulation is quietly working around the clock to keep every organ in your body alive and well.
“Blood flow is how the body powers, protects and repairs itself,” says Brett A. Sealove, M.D., FACC, FAHA, RPVI, CPE, Chair of the Department of Cardiology at Jersey Shore University Medical Center. “Without adequate blood flow, dysfunction of the organ system occurs. If it continues to decline, life is not sustainable.”
So, what’s the one simple thing you can do every single day to support your circulation? According to Dr. Sealove, it’s staying hydrated.
Why Hydration Matters for Your Heart and Circulation
Your blood is about 90 percent water. When you don’t drink enough, your body literally has less blood volume to circulate. That means your heart has to work harder, and your organs may not get the oxygen and nutrients they need.
“Water isn’t just something you drink; it’s something your body needs to work correctly every day,” explains Dr. Sealove. “It is the fuel for your bloodstream and for the engine of the body, namely the heart.”
Even mild dehydration can make a big difference. A one to two percent drop in hydration can reduce the amount of blood your heart pumps by 10 percent each minute, which can impact everything from your brain function to your energy levels. Since the brain itself is about 75 percent water, being dehydrated – even a little – can affect your concentration and mood.
The good news? Dehydration is one of the most modifiable risk factors for circulation. “Staying hydrated improves blood volume, which helps with cardiac function, brain health and keeping your organs nourished,” says Dr. Sealove.
How Much Water Do You Really Need?
The exact amount of water your body needs varies, it depends on things like your metabolism, activity level and environment. But there are some simple signs you’re likely drinking enough:
- You’re using the bathroom regularly
- Your urine is relatively clear
- You’re not waiting until you’re thirsty (since thirst means you’re already dehydrated)
Dry skin, headaches, fatigue and dark-colored urine can all be signs of dehydration.
Don’t Like Plain Water? Try This
If you're having trouble drinking enough water because you think it tastes boring, you're not out of luck. Dr. Sealove suggests these easy ways to liven it up:
- Add a squeeze of lemon
- Try sparkling water for some fizz
- Infuse your glass with fresh herbs or mint
Other Ways to Support Healthy Blood Flow
Hydration is the most important daily step, but it’s not the only one. Dr. Sealove also recommends:
- Regular exercise: Movement improves blood vessel function and helps circulation work more efficiently.
- Eating a nutritious diet: A balanced diet supports the health of your blood vessels.
- Managing stress and avoiding tobacco: Both protect the lining of your blood vessels (endothelial function), which is crucial for circulation.
Final Takeaway
Blood flow powers everything your body does – from thinking clearly to keeping your heart strong. The easiest way to support it? Drink enough water throughout your day.
As Dr. Sealove puts it: “Dehydration is one of the most modifiable risk factors for maintaining health. Staying hydrated helps every organ system in your body.”
So grab a glass of water. Your heart, brain and body will thank you – today and for years to come.
