Adequate hydration plays a fundamental role in the health of your heart. It may seem trivial but drinking a sufficient amount of water every day can help prevent heart problems.
Hydration: a key ally for a healthy heart
To function properly, the heart needs an adequate amount of fluids. This is where water comes in. Water helps maintain normal body temperature, lubricates and cushions your joints, and is critical for heart health .
Water helps maintain the balance of your body fluids. If you don't drink enough water, it can lead to dehydration. Dehydration occurs when you lose more fluids than you take in and it can negatively affect organs and bodily functions, including the heart. This is because dehydration can make the blood thicker and lower blood pressure. This may then require more effort for your heart to pump blood.
How Dehydration Can Affect Your Heart Health
Dehydration occurs when you lose more fluid than you take in. This imbalance can potentially negatively impact your organs and bodily functions, including your heart.
Your heart's function can be hampered by severe dehydration, leading to potentially dangerous conditions like a heart attack or heat stroke. Indeed, the heart must pump harder to keep the thicker blood circulating, which can tire it and ultimately increase the risk of heart disease. Additionally, dehydration can worsen heart function and lead to symptoms such as fatigue, weakness, dark urine, headaches , dizziness, and rapid heart rate.
Maintaining proper hydration levels is crucial to maintaining your heart health. Not only is drinking enough water essential for heart health, but maintaining proper hydration can also reduce the long-term risk of heart failure. People with heart disease, including heart failure, particularly benefit from careful management of fluid intake.
How much water should you drink each day to protect your heart?
The National Academies of Sciences, Engineering, and Medicine recommend adequate fluid intake for the average adult living in a temperate climate. For women, about 11 cups (or 2.7 liters or about 91 ounces) of total fluid intake per day is recommended, and for men, about 15.5 cups (or 3.7 liters or about 125 ounces) .
Interestingly, almost 25% of your daily fluid intake comes from food, and the rest comes from drinks. So it's a good idea to eat water-rich foods like fruits and vegetables to supplement your fluid intake.
Recommendations for people with heart disease
For those battling heart conditions such as heart failure, managing fluid intake is especially important. Healthcare professionals often recommend fluid restriction for these individuals, typically limiting intake to 6-9 cups (or 1.5-2 liters) per day.
This is a contradictory idea, since in most other circumstances we are encouraged to drink more water to stay hydrated and protect our hearts. However, in heart failure, too much fluid can overload the heart and exacerbate symptoms. It is therefore essential to discuss your fluid intake needs with your doctor.
