Cold weather significantly increases the risk of heart attacks

-
Cold weather significantly increases the risk of heart attacks due to several physiological responses. As temperatures drop, blood vessels constrict, raising blood pressure and placing additional strain on the heart. This can lead to increased heart rates and a higher demand for oxygen, which may result in blood clotting. Moreover, engaging in strenuous activities like shoveling snow can exacerbate these risks, especially for those with preexisting conditions. To mitigate risks, individuals should dress warmly, take breaks during physical exertion, and avoid excessive alcohol consumption.
