According to the new findings, cold weather may increase blood pressure risk in the elderly. The study was published in the Jan. 12 issue of the Archives of Internal Medicine.
Although the study does not demonstrate a causal link between blood pressure and external temperature, the observed relationship nevertheless has potentially important consequences for blood pressure management in the elderly.
Study by the Institut National de la Sante et de la Recherche Medicale of Paris, the systolic (top number) and diastolic (bottom number) blood pressures both rose and fell with the change of seasons in the 8,801 people, aged 65 or older.
The average systolic blood pressure, for example, was five points higher in winter than in summer for the participants. Instances of high blood pressure (systolic blood pressure higher than 159, or diastolic higher than 94 millimeters of mercury or higher) were found in 33.4 percent of participants during winter but just 23.8 percent during summer.
