With temperatures touching 40+°C, most people focus on staying cool.But very few realize this:

👉 Extreme heat can silently increase your risk of heart problems.

During heatwaves, hospitals often see a rise in cardiac emergencies, especially among elderly individuals and those with BP, diabetes, or existing heart conditions.

In this blog, we’ll cover:

✔ How heat affects your heart

✔ Why dehydration increases heart attack risk

✔ 5 practical ways to protect your heart

✔ When to consider ECG, 2D Echo, and TMT tests

How Heatwaves Affect Your Heart (Simple Explanation)

When temperature crosses 40°C:

1️⃣ Increased Cardiac Workload

• Blood vessels dilate

• Heart pumps faster to maintain circulation

👉 Result: Your heart works harder than normal

2️⃣ Dehydration & Blood Thickening

• Excess sweating → fluid loss

• Blood becomes more concentrated

👉 Increases risk of clot formation, heart attack, and stroke

3️⃣ BP & Sugar Fluctuations

• BP may drop or fluctuate

• Blood sugar control becomes unstable

👉 Adds extra stress on the heart

⚠️ 5 Ways to Protect Your Heart During Heatwaves

1. Maintain Proper Hydration (Not Just Water Intake)

Don’t wait for thirst.

👉 Follow structured hydration:

• Drink water consistently throughout the day

• Include ORS/electrolytes if sweating heavily

✔ Helps maintain blood flow

✔ Prevents blood thickening

✔ Reduces clot risk

2. Avoid Peak Heat to Reduce Cardiac Load

Between 11 AM – 4 PM, heat stress is highest.

👉 Avoid:

• Outdoor activity

• Heavy exercise

• Direct sunlight

✔ Reduces unnecessary strain on your heart

3. Monitor Blood Pressure & Sugar More Frequently

Heat can cause unpredictable fluctuations.

👉 Especially if you have:

• BP

• Diabetes

✔ Regular monitoring helps detect early changes✔ Prevents sudden complications

4. Maintain Electrolyte Balance

Sweating leads to loss of sodium and potassium.

👉 Include:

• ORS

• Coconut water

• Balanced diet

✔ Helps maintain heart rhythm

✔ Prevents weakness and dizziness

5. Don’t Ignore Early Warning Signs

Heat-related symptoms are often misunderstood.

👉 Watch for:

• Unusual fatigue

• Dizziness

• Chest discomfort

• Breathlessness

⚠️ These can be early signs of cardiac stress
