As winter sets in, many people enjoy the cool, comfortable weather without realizing that a drop in temperature can significantly affect the heart and blood vessels. Numerous studies have confirmed that the incidence of acute myocardial infarction (heart attack) tends to rise during periods of extreme cold.
When the body is exposed to low temperatures, the autonomic nervous system triggers vasoconstriction (narrowing of blood vessels) to conserve body heat. This leads to:
When the heart works harder than usual, the risk of abnormal heart rhythms or acute ischemic heart events increases.
To keep your heart safe and strong in cold weather, follow these recommendations:
Cold weather may make the body feel refreshed, but for the heart, it is a time that requires extra caution. Keeping warm, managing risk factors, and having regular heart check-ups can effectively reduce the risk of heart and vascular diseases.
When temperatures drop, blood vessels constrict to reduce heat loss. This raises blood pressure and forces the heart to pump harder, increasing the risk of ischemic heart events or arrhythmias, especially in people with underlying conditions such as hypertension, diabetes, or high cholesterol.
Because their bodies adapt to cold more slowly than younger people. The blood vessels and heart muscle may function less efficiently. In low temperatures, blood pressure tends to rise and the heart works harder, increasing the risk of heart failure or ischemic heart disease.
If you experience any of the following, seek medical care urgently, as they may signal an acute heart attack:
