Your sleep score hit an impressive 87 last night with nearly 8 hours of sleep, though your HRV dropped significantly to 16 (from 25 yesterday) and resting heart rate increased to 75.5 bpm. This cardiovascular shift suggests your body may be responding to stress or increased recovery demands despite the good sleep duration.
HRV plummeted to 16 from yesterday's 25 - this pattern is often associated with accumulated stress, dehydration, alcohol consumption, or your body working harder to recover from recent activities.
Elevated to 75.5 bpm (above your typical 63-75 range) - this commonly occurs alongside low HRV and may indicate your autonomic nervous system is in a more stressed state.
Dropped to 73 due to extremely poor recovery index (8) - likely linked to the previous night's disrupted sleep with low efficiency (72%) and high wake time (93 minutes).
Your week shows a recovering sleep pattern after the poor night on 19th February (66 score, only 335 minutes). Sleep duration has been highly variable, ranging from 5.6 to nearly 8 hours, with last night's 478 minutes being your longest this week. However, today's cardiovascular metrics (low HRV, elevated RHR) suggest your body is working harder despite the good sleep duration, indicating possible accumulated stress or recovery debt.
Moderate positive correlation (r=0.67, n=31): when sleep efficiency increases tend to coincide with increases in sleep score.
Moderate positive correlation (r=0.61, n=30): when resting heart rate increases tend to coincide with increases in sleep score.
Moderate negative correlation (r=-0.54, n=30): when sleep duration increases tend to coincide with decreases in HRV.
Moderate positive correlation (r=0.53, n=30): when deep sleep increases tend to coincide with increases in readiness score.
Moderate negative correlation (r=-0.51, n=30): when HRV increases tend to coincide with decreases in sleep score.
