Winter Increases Heart Attack Risks
Heart attacks are a big problem worldwide, and they happen more often in winter.
When it's cold, our blood vessels get smaller, making our hearts work harder.
We also move less, eat more unhealthy food, and get sick more easily, all of which can hurt our hearts.
To stay safe, we should dress warmly, move carefully in the cold, exercise inside, eat healthy foods, and check our health often.
This can help keep our hearts strong even in winter.
Heart attacks are a leading cause of death globally, with 19.8 million CVD deaths in 2022, 85% due to heart attack and stroke.
Winter increases heart attack risk due to vasoconstriction, reduced physical activity, respiratory infections, and stress.
Vasoconstriction in cold weather raises blood pressure and increases heart strain, especially for those with blocked arteries.
Prevention tips include dressing warmly, avoiding sudden strenuous activity, maintaining indoor physical activity, eating a heart-healthy diet, and monitoring health metrics.
People with existing heart conditions, hypertension, or diabetes are particularly vulnerable during winter.
