Cold weather often increases blood viscosity and vasoconstriction, which can lead to higher blood pressure and greater cardiac workload — factors that can show up on ECG tracings. This article would explain the connection between cold-induced physiological changes, ECG findings, and long-term heart risk. It offers a balanced mix of science and tips to help readers navigate winter safely. https://sunfox.in/blogs/how-does-cold-weather-affects-your-heart/
