VV Signal Score
83
Strong signal
Poor sleep tracks with inflammation, chronic disease, and mortality risk. The signal is meaningful, but the strongest outcome evidence is observational—not proof that a better sleep score adds years to life.
VV Signal Score
65
Promising signal
Wearables can reveal patterns, but sleep scores, HRV, and recovery numbers are estimates rather than diagnoses.
