Wintertime and cold weather remarkably increase the risk of cardiovascular morbidity and mortality. There is an excess of ca. 2000-3000 deaths occurring in Finland during the winter and even half of them are for cardiovascular reasons. Both acute and and repeated exposures to cold increase blood pressure and may contribute to the higher wintertime cardiovascular morbidity and mortality. It has been suggested, that cold-related cardiovascular deaths could be prevented by proper protection from cold temperature.
