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
Continuous glucose monitors are moving from diabetes care into consumer metabolic self-tracking. That can help some people understand meals, sleep, stress, exercise, and risk. It can also turn normal physiology into false precision, food fear, and subscription anxiety.
VV Signal Score
58
Early or context-dependent
Wearables can reveal patterns, but sleep scores, HRV, and recovery numbers are estimates rather than diagnoses.
News cycle
Dexcom's Stelo Glucose Biosensor System is now cleared for over-the-counter use in people ages 2 and older who do not use insulin.
Why now
FDA clearance moves over-the-counter metabolic tracking into childhood for the first time.
