Key result
Outside temperatures ≥10°C were inversely associated with home blood pressure, with a 1°C increment corresponding to a 0.40 mmHg decrease in systolic and 0.28 mmHg decrease in diastolic pressure.
Observational (n=79)
Effect estimate: 0.40 mmHg decrease in SBP and 0.28 mmHg decrease in DBP
An inverse association between outside temperature and home blood pressure is evident only in warmer seasons (≥ 10°C), suggesting that modern heating systems may blunt this effect in colder months.

May inform seasonal BP monitoring adjustments; leaves open heating's mitigation of winter effects in larger studies.
Hozawa et al. (2011) reported an observational. Outside temperature ≥10°C vs. Outside temperature <10°C was evaluated on Change in systolic and diastolic blood pressure per 1°C increment in outside temperature (0.40 mmHg decrease in SBP and 0.28 mmHg decrease in DBP). Outside temperatures ≥10°C were inversely associated with home blood pressure, with a 1°C increment corresponding to a 0.40 mmHg decrease in systolic and 0.28 mmHg decrease in diastolic pressure.
