Stroke mortality in Miyagi, Japan.
Hypertension is a major cause in stroke mortality in Japan but is not the sole factor. This research, based on geographical comparisons between two selected towns of contrasted stroke experience, implicates a poor indoor thermal environment as having an important role, especially by sudden changes in temperature between rooms elevating blood pressure. High dietary salt is also an important contributory cause of stroke and is already the target of a public education campaign to encourage a reduced intake.
