Your Mood Pattern

The data tells a quiet story. On days when sleep dipped below six hours, your average mood score fell to 3.2 — a full 4.1 points below your baseline of 7.3 on well-rested days. The effect compounds: when you also consumed more than three cups of caffeine that same morning, the drop deepened to 5.8 points below baseline.

Social time emerged as a surprising buffer. Even on high-workload days (rated 8 or above), spending at least one hour with friends or family lifted your mood by an average of 2.4 points. But on the three days where social time was zero — May 15, 18, and 21 — your mood never broke above 5, and twice hit 2 or 3.

Perhaps the starkest signal came from workload itself. The correlation coefficient between workload and mood was -0.81, making it the single strongest predictor in your dataset. When workload hit 9 or 10, your sleep also suffered — those nights averaged 4.5 hours, creating a feedback loop that took two days to break.

By Friday, May 16, you logged 8.5 hours of sleep, one cup of caffeine, and four hours of social time. Your mood hit 9 — a near-perfect day. The contrast with Wednesday, May 14, is instructive: similar workload (6 vs. 5), but sleep was 7 hours and caffeine was 3 cups. Your mood was 6, not terrible, but noticeably lower. The data suggests that even modest changes in sleep and caffeine create measurable differences in how you feel.
