Why Summer Can Be Hard on Your Heart

• Heat causes your heart to work harder to cool your body

• Dehydration thickens the blood and increases heart workload

Extreme heat and dehydration can increase cardiac strain, especially in people already at risk of heart attack, making early prevention even more important. Understanding these risks helps you take better care of your heart.

1. Stay Properly Hydrated

• Drink water regularly, even if you do not feel thirsty

• Aim for small sips throughout the day instead of large amounts at once

• Coconut water, lemon water, and diluted fruit juices help replace electrolytes

• Avoid sugary sodas and packaged drinks as they strain the heart

People living with hypertension should be extra cautious in summer, as dehydration and excess salt can cause dangerous blood pressure fluctuations.

Tip: Pale yellow urine usually indicates good hydration.

2. Eat Heart-Friendly Summer Foods

• Choose fresh fruits like watermelon, berries, oranges, and papaya

• Add vegetables such as cucumber, spinach, tomatoes, and bottle gourd

• Prefer grilled, steamed, or boiled foods over fried meals

Healthy food keeps cholesterol under control and reduces inflammation. Following a balanced heart-healthy diet rich in fruits, vegetables, and whole foods supports healthy cholesterol levels and reduces inflammation.

Quitting smoking is one of the best gifts you can give your heart.

Early action can prevent serious heart complications.
