How Cold Weather Impacts Heart Health

Cold temperatures can affect your cardiovascular system in several significant ways. In cold weather, your body naturally works to conserve heat, causing blood vessels to constrict. This constriction can increase blood pressure & heart rate, putting additional strain on the heart. For individuals with pre-existing heart conditions, this added stress can trigger serious health issues, including heart attacks.

Furthermore, winter often brings about lifestyle changes that can negatively affect heart health. People tend to become less active during colder months, leading to weight gain and increased cholesterol levels. Seasonal affective disorder (SAD) can also contribute to depression and anxiety, which are known risk factors for heart disease.
