Winter BP and variability rises may influence monitoring timing in mild hypertension; leaves open causal temperature effects.
Do seasonal changes in environmental temperature affect 24-hour ambulatory blood pressure and short-term BP variability in stage I hypertensive subjects?
Blood pressure and its short-term variability are significantly higher during the cold season in patients with mild hypertension, suggesting clinical assessments may yield different results depending on the season.
Winnicki et al. (1996) studied this question.
