Your glucose rises an average of +1.0 mmol/L between 5am and 7am without any food or insulin activity. This is consistent with dawn phenomenon - a natural cortisol-driven rise in blood sugar in the early morning hours.
Post-lunch BG peaks at an average of 12.8 mmol/L, typically 75-90 min after eating. Your current bolus timing is pre-meal by 5 min, but your insulin-to-carb ratio may need reviewing for lunches specifically - pattern shows consistent under-coverage.
On days with a 20–40 min low-intensity walk (afternoon, 3–5pm window), your overnight TIR improves by an average of +14 percentage points. This is the single most consistent positive pattern in your data.
Your average time from meal log to bolus has decreased from 12 min to 6 min over the last 3 weeks. This correlates with a measurable reduction in peak post-meal glucose from 13.8 to 12.1 mmol/L on average.
On days following sleep scores above 75 (Garmin), your next-day TIR averages 79%. Following poor sleep (<60), it drops to 64%. This is a statistically significant correlation across 14 days of paired data.
Overall: Solid week with clear patterns to work with. Your average TIR of 78% is above the international target of 70%. The main opportunity is post-lunch glucose management - addressing your pre-bolus timing alone could push TIR to 83%+. Exercise consistency continues to be a strong positive factor. Two nighttime lows recorded (both mild, both self-treated). Dawn phenomenon is consistent and worth discussing with your team.
