Figure 1. Daily stress. Upper: Average stress values for all the test subjects in 15-minute intervals (measured for each as the share of seconds that exceed the average in each 15-minute interval). Lower: percentage of seconds of stress more than twice as high as the average in 15-minute periods. The 15-minute interval of each test subject is compared to their personal average over approximately 10-day periods.
