Key result
A 1 °C decrease in the 14-day moving average mean air temperature was associated with a 0.54% (95% CI 0.41-0.68) increase in systolic blood pressure.
Why the study?
Ambient air temperature and temperature variability are supposed to influence blood pressure, but findings have been inconsistent.
Do short-term changes in ambient temperature and temperature variability affect blood pressure in a general population?
Observational (n=3,184)
No

Effect estimate: 0.54% increase (95% CI 0.41-0.68)
Decreases in ambient air temperature and diurnal temperature range are associated with increases in systolic, diastolic, and mean arterial blood pressure.
No takes yet. Share an insight, caveat, or question.
Lower ambient temperatures and reduced variability were associated with higher BP; leaves open whether seasonal monitoring or interventions merit trials.
Woeckel et al. (2023) conducted an observational in Blood pressure (n=3,184). Decreases in ambient air temperature and diurnal temperature range was evaluated on Systolic BP (SBP), diastolic BP (DBP), mean arterial pressure (MAP), and pulse pressure (PP) (0.54% increase, 95% CI 0.41-0.68). A 1 °C decrease in the 14-day moving average mean air temperature was associated with a 0.54% (95% CI 0.41-0.68) increase in systolic blood pressure.
