Lars Sondergaard, cardiologist: "Water helps the heart pump blood more efficiently."

Cardiovascular diseases remain a challenge for Spain due to its high mortality rate. With a strong impact on heart health and blood circulation , these conditions are behind cases of heart attacks, arrhythmias, heart failure, and hypertension . In fact, high blood pressure is spreading like an epidemic among the population, especially those who are sedentary and have unhealthy habits. Ultra-processed foods are among the risk factors , which is why medical professionals always emphasize the importance of including a healthy diet full of protein, vegetables, fruits, and fiber every day.
However, in this quest for healthy eating, the importance of hydration is often forgotten. In this regard, cardiologist Lars Sondergaard has warned against common practices that, while initially considered healthy, such as smoothies or fruit juices, can also have a negative impact on heart health . Therefore, he emphasizes the use of water every day, not only to keep the body free of toxins, but also to maintain blood circulation.
The benefits of drinking water for circulation, according to a cardiologistWater is generally considered the kidneys' best friend , as it supports kidney function by cleansing and releasing toxins, as well as excess sodium. However, this latter process also contributes to improved heart function.
"When a person is dehydrated, their blood can become thicker and more prone to clotting, which can increase the risk of cardiac events. Drinking enough water can help your heart pump more efficiently , as it doesn't have to work as hard to move blood," explains Dr. Lars Sondergaard.
Drinking the recommended amount of water, typically around 2 liters a day , also has a positive impact on preventing heart failure. " Water helps the body maintain proper electrolyte balance, which is crucial for healthy heart rhythm and function . These factors, together, contribute to a lower long-term risk of these diseases," the cardiologist adds.
Now, some of the problems arise when people begin to reduce their water consumption and turn to other liquids for hydration . It's well known that sugary soft drinks are not recommended due to their high sugar content, which is why some people turn to fruit juices or natural smoothies as an alternative. However, this can also have a negative impact.
Cardiologists urge replacing juices with waterFruit juices contain high levels of sugar , whether natural or added, with the latter being much worse, as they are typically the ones sold on the market. That's why cardiologists urge extreme caution when incorporating them into our diets. They don't have to be banned when it comes to natural juices , but experts do recommend replacing most of them with glasses of water.
"A diet high in added sugars can negatively affect heart health, contributing to weight gain, high blood pressure, increased inflammation, and unhealthy cholesterol levels—all risk factors for heart disease," explains cardiologist Estelle Jean. Dr. Lars Sondergaard also emphasizes: " Excessive sugar consumption can cause chronic inflammation in the blood vessels and lead to fatty liver disease, which increases the risk of cardiovascular events such as heart attacks and strokes."
