According to recent forecasts from the meteorological agency, an extreme heatwave with temperatures around 38 degrees Celsius is expected to continue in our country for some time. Amidst this intense heat, the most crucial aspect to watch out for is heart health. A report from the U.S. Centers for Disease Control and Prevention (CDC) indicates a surge in hospitalizations for cardiovascular diseases as the heat intensifies. Let's explore how we can protect our hearts during these heatwaves.

Symptoms of Heat Exhaustion

Exposure to a heatwave can lead to symptoms like headaches, dizziness, and nausea. Your skin may become clammy, and your body might struggle to regulate its temperature. If you experience these symptoms, move to a cool place and use a cool, damp cloth to lower your body heat. If symptoms don't improve after an hour, it's advisable to seek immediate medical attention. Heatstroke, in particular, is very dangerous, so if you notice a rapid and strong pulse, a rising body temperature, and flushed skin, get to a hospital right away.

Light Meals and Ample Hydration

During a heatwave, body temperature regulation significantly impacts blood flow. A healthy body circulates blood to the skin to dissipate heat. However, overeating diverts blood to the digestive system, making heat dissipation more difficult. Therefore, it's important to eat light meals and consume water-rich fruits and vegetables like watermelon and cucumber.

• It's recommended to drink 1.5 to 2 liters of water per day.
• Alcoholic beverages, especially beer, should be avoided as they can cause dehydration.

Manage Your Time Wisely

On days with severe heatwaves, avoiding direct sunlight is paramount. The National Emergency Management Agency also advises against outdoor activities between 2 PM and 5 PM during the summer. It's best to schedule your outings for the morning or evening and maintain a consistent daily rhythm.

Exercise with Caution

While exercise is essential year-round, it's crucial to avoid strenuous activity in the heat. Jogging or cycling in the midday sun can be risky, so exercising indoors is a safer option. Incorporating exercise that considers the specific conditions of summer will greatly help in maintaining heart health.

Frequently Asked Questions

• How does hot weather affect the heart? When temperatures rise, blood vessels dilate, and the heart must pump more blood to circulate it. Dehydration can further strain the heart.
• Does a heatwave increase the risk of heart attack? Yes, heatwaves increase the heart's oxygen demand and can lead to dehydration, thereby raising the risk of heart attack.
• How does blood pressure change in hot weather? Blood vessels dilate, which can lower blood pressure. However, severe dehydration can lead to unstable blood pressure.
• How much water should I drink daily for heart health? It's best to drink small amounts frequently, even before you feel thirsty.
• What symptoms during hot weather are warning signs? Chest pain, severe shortness of breath, dizziness, and a feeling of irregular heartbeat are all warning signs.
• What foods are good to eat during a heatwave? It's important to consume plenty of heart-healthy foods such as fruits, vegetables, whole grains, fish, and legumes.

Maintaining a healthy heart during a heatwave requires careful attention. Individuals with pre-existing cardiovascular conditions should be particularly cautious, but small changes in daily routines can significantly contribute to heart health. Let's face the heat and have a healthy summer!
