Winter Increases Heart Attack Risks Due to Cold-Weather Triggers
Winter increases the risk of heart attacks because cold weather makes blood vessels narrower, which raises blood pressure and makes the heart work harder.
Cold weather also makes blood thicker, which can lead to blood clots.
Additionally, people tend to eat richer foods, drink more alcohol, and be less active during the winter, which can also harm heart health.
Doctors advise staying warm, avoiding sudden cold exposure, taking medications as prescribed, and staying active to reduce the risk of heart attacks during winter.
Cold weather causes blood vessels to constrict, raising blood pressure and increasing heart workload.
Thicker blood due to dehydration in cold weather increases the risk of blood clots and heart attacks.
Festive-season habits like rich food, excess salt, and alcohol intake further compound heart attack risks.
Elderly people and those with pre-existing heart conditions are at higher risk during winter.
Preventive measures include dressing warmly, avoiding sudden cold exposure, staying active, and seeking medical attention for warning signs.
