As winter sets in, experts warn that heart attack cases tend to rise significantly. Before the Covid pandemic, India recorded over seven lakh sudden heart-attack deaths annually, and the number may have increased since then.
Cold weather especially affects elderly individuals and those with diabetes, hypertension, obesity, or smoking habits, putting them at higher risk. Low temperatures cause blood vessels to constrict, forcing the heart to work harder and increasing the chances of cardiac emergencies.
At Rhythm Hospital, we observe a noticeable surge in heart-related cases during winter, highlighting the importance of awareness and timely action.
Understanding why winter increases heart attack risks and learning how to stay protected can help safeguard your health. As temperatures drop, staying cautious, adopting healthy habits, and seeking prompt medical care can truly be life-saving.
Winter and Heart Attacks: Why Risks Increase & How to Stay Safe
During winter, the risk of heart attacks increases because cold temperatures cause blood vessels to constrict, raising blood pressure and putting extra strain on the heart.
People with diabetes, hypertension, obesity, or existing heart disease are especially vulnerable during harsh weather. Reduced physical activity and seasonal infections can further heighten cardiac stress.
To stay safe, it’s important to keep the body warm, stay active indoors, monitor blood pressure, eat heart-healthy foods, and avoid sudden exposure to cold.
7 Key Reasons & Prevention Tips
1. Cold Weather Narrows Blood Vessels
When temperatures fall, blood vessels tighten, restricting blood flow to the heart. This narrowing forces the heart to work harder, which may trigger a heart attack in vulnerable individuals.
Staying warm, wearing layered clothing, and avoiding sudden exposure to cold winds are essential steps to reduce winter-related cardiac strain.
2. Increased Blood Pressure in Winter
Cold weather makes it harder for the body to stay warm, so it works harder and blood pressure goes up. This can be risky for people who already have high blood pressure.
To stay safe during winter, it’s important to check blood pressure regularly, avoid eating too much salt, and limit heavy activities when it’s really cold.
This helps prevent sudden heart problems.
3. Higher Risk of Blood Clots
Cold weather makes blood thicker, which can lead to more clots. For people with coronary artery disease, this can be very dangerous and might cause a heart attack.
Drinking enough water, keeping homes warm, and not staying still for too long can help lower the risk of blood clots a lot.
4. Overexertion in Cold Weather
Many people exert themselves without realizing the strain, whether it’s shoveling snow, brisk walking, or sudden physical activity.
Overexertion amplifies the heart’s workload in winter. Taking frequent breaks, warming up before any physical activity, and avoiding sudden intense exertion are vital safety measures.
5. Reduced Physical Activity in Winters
When days get shorter and nights get colder, people tend to be less active. Not moving much can make blood flow worse and raise cholesterol.
Even in winter, doing light exercises inside, stretching, or taking short walks can keep the heart healthy and avoid stiffness or heart issues.
6. Winter Infections & Flu Affect the Heart
Cold weather can increase the risk of flu, viral infections, and respiratory issues, and other services, it can indirectly affect the heart.
When the body fights infection, the heart works harder. Getting vaccinated, improving immunity, and resting well during illness can prevent inflammation-related cardiac events.
7. Seasonal Stress & Lifestyle Changes
The winter season can bring stress from holidays, changes in daily habits, eating too much, and less sunlight, things that can hurt heart health.
To keep your heart healthy during winter, it’s good to manage stress with meditation, watch your food portions, and stay on a regular sleep schedule.
