Super Bowl Sunday Was Fine. Monday Wasn't.
Super Bowl LX took place on Sunday, February 8. We expected to see an impact on Body Feedback Scores — but not where we expected it.
Sunday (Feb 8) came in at 53.1 nationally — completely in line with the typical Sunday average of 53.6. Whatever excitement, snacking, or late-night watching happened, the body didn't register it yet.
Monday (Feb 9) dropped to 50.0 — a 3.1-point decline. For context, the previous Sunday-to-Monday transition (Feb 1→2) only saw a 1.2-point drop. The post-Super Bowl Monday was 2.6× worse than a normal Monday transition.
The State-Level Story
The national average doesn't tell the full story. Some states saw dramatic overnight changes:
| State | Feb 8 (Sun) | Feb 9 (Mon) | Change |
|---|---|---|---|
| New York | 57.3 | 37.7 | -19.7 |
| Arizona | 68.3 | 51.0 | -17.3 |
| Illinois | 53.4 | 42.4 | -11.0 |
| Colorado | 46.8 | 38.6 | -8.2 |
| Florida | 62.0 | 54.1 | -7.9 |
| Texas | 57.0 | 53.4 | -3.6 |
New York and Illinois — both major metro areas with high Super Bowl viewership — saw the largest drops. New York fell from the Normal zone (57.3) into Attention (37.7) in a single day.
Not Everyone Dropped
A few states actually improved:
- Indiana: 32.3 → 40.3 (+8.0)
- Washington: 41.7 → 46.0 (+4.3)
- Michigan: 48.7 → 51.5 (+2.8)
Whether this reflects different viewing habits, time zones, or simply sample variation is an open question.
What Likely Happened
Body Feedback Scores are based on HRV and resting heart rate. Late nights, alcohol consumption, high-sodium snacks, and emotional arousal (win or lose) are all known to suppress HRV and elevate resting heart rate the following day.
The effect appears and resolves quickly: by Tuesday (Feb 10), the national average recovered to 51.9.
Takeaway
Major cultural events may not show up in biometric data on the day itself — but the physiological aftereffects are measurable the next morning. The body processes the experience overnight, and the data captures it.
