As temperatures drop, the risk of heart-related emergencies rises sharply, cautions Dr. M. D. Dixit, Chief Cardiac Surgeon & Director at Arihant Hospital, Belagavi.
Dr. Dixit explains that exposure to cold causes blood vessels to tighten, which increases blood pressure and forces the heart to work harder. “Without adequate warm clothing, individuals are more likely to experience chest pain, breathlessness, and in severe cases, heart attacks,” he said.
Winter also tends to trigger lifestyle changes that negatively impact heart health. Reduced physical activity, increased consumption of oily and fried foods, and lower vitamin D levels all contribute to a higher risk of heart attacks and strokes. The body also releases more adrenaline in low temperatures, raising heart rate and blood pressure, while thicker blood increases the chances of dangerous clots.
He further advised elderly individuals to avoid breathing exercises in gardens and open areas during early mornings, as cold air can irritate the lungs, reduce oxygen intake, and strain the heart. Dust and smoke pollution can further worsen the situation.
People with existing cardiac conditions — including those who have undergone angioplasty or heart surgery, or those being treated for high blood pressure or coronary artery disease — need to be especially careful in winter.
Dr. Dixit urged immediate medical attention for anyone experiencing:
- Chest pain or tightness
- Discomfort spreading to the shoulder, arm, back, neck, jaw, or teeth
- Excessive sweating, dizziness, heartburn, or nausea
Recommended Precautions for Heart Safety in Winter
- Avoid early morning walks; step out only after sunrise.
- Wear proper winter clothing, covering head, chest, hands, and feet.
- Limit oily, fatty, and deep-fried foods.
- Opt for light indoor exercise.
- Avoid night travel during winter.
- Do not skip prescribed BP, diabetes, or cardiac medicines; visit your doctor regularly.
Dr. Dixit emphasizes that timely precautions and awareness can prevent winter-related cardiac emergencies and help individuals stay safe and healthy.
