New proof that cold weather can give you a stroke

Changes in temperature and dew points can increase the probability that a person will have a stroke according to research conducted by Dr. Judith H. Lichtman, associate professor in Epidemiology at the Yale School of Public Health in New Haven, Connecticut that was presented at the Feb. 13, 2014, session of the American Stroke Association's International Stroke Conference.

Large changes in temperature during a day, higher moisture content in the atmosphere as indicated by dew points, and low temperatures were implicated as producing higher risks for strokes that are caused by a blood clot that blocks blood flow in or leading to the brain.

A single degree increase in temperature reduced the chances of stroke and reduced the potential to die from a stroke by at least one percent according to an analysis of 134,510 people that were 18 years of age and older that were admitted to hospitals due to having a stroke between 2009 and 2010.

Considering the cold temperatures caused by a polar vortex and the unusually cold temperatures in the southern United States that has already been designated as the stroke capital of the United States, one might expect considerably more strokes to occur in 2014 than have occurred during the previous few years with milder winters.
