Summer Cardiovascular Care: How to deal with soaring temperature

The scorching summer months pose a unique challenge for maintaining cardiovascular health . With rising temperatures comes a significant increase in cardiovascular disease (CVD) morbidity and mortality. Studies have shown a concerning correlation: a mere 1-degree Celsius rise in temperature translates to a 2.1% jump in CVD deaths and a 0.5% rise in related illnesses.

These risks are particularly amplified for vulnerable populations in tropical regions and during heatwaves.

Here, we delve into key strategies to safeguard your cardiovascular health during the summer:

Hydration as the Cornerstone: Adequate fluid intake is paramount for optimal heart function and stroke prevention. Dehydration thickens the blood, raising the risk of blood clots that can lead to stroke. For individuals with heart failure, managing fluid balance is crucial. Consulting your cardiologist is essential to determine the appropriate fluid intake, particularly during hot weather and physical activity. Generally, aiming for 8-10 glasses of water daily is a good starting point.

Vigilance with Blood Pressure : High blood pressure is a well-established risk factor for both heart disease and stroke. Consistent monitoring and strict adherence to your doctor's recommendations are vital.This includes medication, lifestyle adjustments, and dietary modifications. Consider incorporating summer fruits and vegetables with high water content into your diet, as these can help regulate body temperature. Additionally, limiting processed foods and maintaining proper fluid intake are key.

Combating Cholesterol

Elevated cholesterol levels contribute to the buildup of plaque in arteries, significantly increasing the risk of stroke and heart disease. A heart-healthy diet low in saturated fats and cholesterol is essential. Opt for fresh summer fruits and vegetables, and avoid processed snacks altogether.

Exercising with Caution

While regular physical activity is crucial for cardiovascular health, strenuous workouts under extreme heat can be detrimental. Choose cooler times of the day to exercise and prioritize hydration to prevent heat-related illnesses. Consider lower-intensity activities like yoga during peak heat hours.

Nutritional Strategies: A balanced diet rich in fruits, vegetables, whole grains, and lean protein is a cornerstone of cardiovascular health. Minimize salt intake and processed foods, and focus on seasonal produce for optimal hydration and nutrient intake.

Alcohol Moderation or Abstinence: Excessive alcohol consumption elevates blood pressure and stroke risk. Additionally, alcohol contributes to dehydration, further highlighting the importance of moderation during the summer. Consider adhering to recommended daily intake guidelines or abstaining altogether. Similarly, limit caffeine intake and avoid sugary beverages.

Quit Smoking: Smoking is a significant cardiovascular risk factor. Quitting smoking is paramount for improving heart health and reducing stroke risk.



Stress Management Techniques: Chronic stress is a known exacerbator of cardiovascular risk factors. Employing stress-reduction techniques such as mindfulness meditation and deep breathing exercises can be highly beneficial.

Knowledge is power: Familiarize yourself with the warning signs of stroke and seek immediate medical attention if you suspect a stroke.

By integrating these essential strategies into your summer routine, you can significantly reduce your risk of heart attack and stroke. Additionally, it's vital to prioritize the well-being of vulnerable populations during extreme heat, including the elderly, individuals with existing CVD, children, and those requiring care assistance.
