Summer is a season of sunshine and outdoor fun, but for your heart, it can pose hidden challenges. When temperatures soar above 80°F, your cardiovascular system faces extra pressure. Dr. Sarita Rao, the best cardiologist in Indore, emphasises, “When it’s hot, your heart rate usually increases as it works harder to keep your body cool. This extra effort can cause dehydration, abnormal heart rhythms, and even heart attacks.” Understanding how summer heat affects your heart and taking proper precautions can help you stay safe and healthy during the hottest months.

The Impact of Heat on Heart Health

1. Increased Heart Rate

Hot weather causes your body to work harder to cool itself, leading to an increased heart rate. For individuals with existing heart conditions, this added stress can be dangerous.

2. Dehydration and Low Blood Pressure

Excessive sweating in the heat can lead to dehydration, reducing blood volume and causing low blood pressure. This can result in dizziness, weakness, and fainting, posing risks for those with heart problems.

3. Blood Vessel Expansion

Heat causes blood vessels to expand, which can lower blood pressure and disrupt the heart’s normal rhythm, leading to complications like arrhythmias.

4. Heat Exhaustion and Stroke

In extreme heat, the body may struggle to regulate temperature, leading to heat exhaustion or stroke. These conditions can cause severe complications, including heart attack or stroke, especially for those with underlying heart disease.

Precautions for a Healthy Heart in Summer

• Stay Hydrated: Drink plenty of water throughout the day to prevent dehydration.
• Avoid Peak Heat Hours: Limit outdoor activities during the hottest parts of the day, typically between 10 a.m. and 4 p.m.
• Wear Appropriate Clothing: Opt for lightweight, loose-fitting, and light-colored clothing to help keep cool.
• Use Cooling Measures: Utilize fans, air conditioning, or cool compresses to maintain a comfortable body temperature.
• Monitor Health Symptoms: Be vigilant for signs of heat-related illnesses, such as dizziness, nausea, or confusion, and seek medical attention promptly.
