Scoring for this category is still being researched — your inputs below are saved and ready for when it ships.
A directional, educational estimate built on published research — not a clinical measurement or a diagnosis.
Inputs
Habits, not one-time measurements — answer honestly, nobody sees this but you.
What moves it
- Quitting smoking at any age produces measurable risk reduction within years, not decades.
- Sleep quality affects nearly every other category on this site — recovery, metabolism, mood, and injury risk.
- Consistency in exercise frequency matters more than intensity for most long-term outcomes.
- Alcohol's effects are dose-dependent — the trend over months matters more than any single week.
Solutions, scaled to you
A low score is never a dead end — it just changes where you start. Pick whichever matches what’s actually available to you right now.
On your own
- Track sleep and exercise for two weeks before changing anything — a real baseline beats guessing.
- Set a specific, small exercise-frequency target and hit it consistently before raising it.
