- Primary Outcome Measures
Name Time Method Correlation of daily rhythmicity among the following measurements is explored as primary outcomes. Intrinsic factors such as salivary cortisol, melatonin, and microbiota in the oral cavity, along with heart rate, activity (exercise, walking, and calorie consumption), sleep (including but not limited to wakeup time and bedtime), subcutaneous glucose levels, in combination with diurnal variation of external factors such as eating behavior and housing environments (temperature, humidity, illumination, air pressure, noise, carbon dioxide concentration, air quality, ultraviolet levels, discomfort index, heat stroke risks, opening motions of refrigerators, and electricity usage) are evaluated.
