Design outcomes

Primary

MeasureTime frame
During the summer season (July-September) and winter season (December-February), we will measure blood pressure upon waking, before bedtime, and during the night at home and in model homes. This will verify differences in seasonal variations caused by the home environment.

Secondary

MeasureTime frame
Using continuously measured heart rate and activity levels from an activity monitor, we perform stress indicator analysis (autonomic nervous system analysis) and sleep analysis, and conduct exploratory analysis of their relationship with blood pressure and residential environment information.
