Researchers with the American College of Cardiology have reviewed decades of data that show heart attacks, strokes and coronary artery disease are significantly more deadly in cold months than warm ones.

A recent study has found that cold weather can be a significant hidden risk for individuals with heart disease. While the dangers of hot weather for cardiovascular health are widely recognized, researchers now report that exposure to extreme cold may be even more deadly.

The study indicates that cold temperatures can cause blood vessels to constrict, elevate blood pressure, and increase the risk of blood clotting. Analysis of temperature-related deaths suggests that cold weather may be nearly 20 times more deadly than heat for those with pre-existing heart conditions.
