This study aimed to demonstrate antihypertensive effects by moving to high thermal insulation performance houses. Field surveys on home blood pressure and indoor temperature were conducted before and after moving in winter 2014 and 2015. Systolic blood pressure (SBP) decreased by 1.5 mmHg per 1 °C increase in indoor air temperature and standard deviation (SD) of SBP improved by 2.3 mmHg per 1 °C improvement in SD of indoor air temperature in a group over 125 mmHg. However, to raise indoor temperature, it is not satisfied only by moving to high thermal insulation performance houses but adequately heating a room.
