More Fatal Strokes in Winter

Now you have another reason to welcome spring: People are more likely to have a particular kind of highly-fatal stroke in colder months. Doctors in Hong Kong have found that January is the month when most aneurysmal subarachnoid hemorrhages occur. The mortality rate for this type of stroke comes in at 50 percent, and most people who have one die on the day of the event.

Changes in atmospheric pressure appear to play a role in whether someone has this type of stroke. Smoking and high blood pressure have also been linked to it as well, which is a good reason for giving up the habit and having your blood pressure monitored regularly.
