As temperatures soar during the summer, the risk of heart attacks also rises significantly. Heatwaves aren’t just uncomfortable — they can be dangerous, especially for people with existing heart conditions. Excessive sweating, dehydration, and thickening of the blood put extra pressure on the heart, increasing the risk of heart-related emergencies.
Why Does Heart Attack Risk Rise in Summer?
When the body loses too much fluid through sweat, it leads to dehydration. This reduces blood volume and causes the blood to thicken. As a result, the heart must work harder to circulate blood, raising both blood pressure and heart rate. These physiological changes increase the chances of a heart attack, particularly in people who already have heart problems.
How Heat Stroke Affects the Brain
Extreme heat doesn’t just strain the heart; it also affects the brain. Heatstroke can cause inflammation in brain tissues, potentially leading to brain hemorrhage. Lack of electrolytes due to sweating and dehydration can disrupt the body’s balance, leading to neurological issues in severe cases.
Common Issues Faced by Heart Patients in Hot Weather
According to cardiologist Dr. Prashant Kothari, regular heart patients often face increased blood pressure during summer. Due to thickened blood and fluid loss, medications may need adjustment. The heart rhythm may become unstable, and patients might experience fatigue, dizziness, or palpitations even with normal activity levels.
Tips to Keep Your Heart Safe in the Heat
. Stay Hydrated – Drink at least 3 liters of water daily. If you’re stepping out in the sun, increase intake to 4 liters
Avoid Sugary and Fizzy Drinks – Skip cold drinks and sodas. Opt for homemade lemonade or salt-sugar water to maintain electrolyte balance.
Eat Water-Rich Foods – Include potassium-rich fruits and vegetables like bananas, watermelon, cucumber, and coconut water in your diet.
Stay in Cool Spaces – Use air-conditioned rooms or fans to avoid heat exposure, especially during peak afternoon hours.
Avoid Heavy Exercise Outdoors – Reduce intense physical activity during the day to prevent overexertion.
Summer can be a tough season for your heart, but the right steps can go a long way in protecting your cardiovascular health. Whether you’re a heart patient or simply health-conscious, staying cool, well-hydrated, and informed is the key to beating the heat without stressing your heart
