Cold-induced vasodilation (CIVD) is a cyclic oscillation in blood flow that occurs in the extremities on cold exposure and that is likely associated with reduced risk of cold injury (e.g., frostbite) as well as improved manual dexterity and less pain while working in the cold. The CIVD response varies between individuals, but the within-subject reproducibility has not been adequately described....

PURPOSE To describe the self-reported ambient cold exposure in northern Sweden and to relate the level of cumulative cold exposure to the occurrence of sensory and vascular hand symptoms. We hypothesize that cold exposure is positively related to reporting such symptoms. METHODS A questionnaire about cold exposure and related symptoms was sent out to 35,144 subjects aged 18-70 years and livin...

Cold regions have their unique hazards such as hypothermia and frostbite. Hence, these hazards must be taken into account very early in the design phase. Moreover, risk analysis approaches should be updated to take into account the specific hazards of the Cold Climate region. There can be a high dependence between different cold region hazards and a combination of failures can happen during an ...

BACKGROUND Injury is a major public health concern, particularly for Canadians living in Arctic regions where the harsh physical and social conditions pose additional challenges. Surveillance data collected over the past 2 decades through the Canadian Hospitals Injury Reporting and Prevention Program (CHIRPP) provide insights into the burden of injuries in certain parts of Canada. OBJECTIVES ...
