UseWhen to use: shift work, sedation recovery, or sleep-disorder follow-up needing a now-rating.
StrataHigher = sleepier; ≥6 generally unsafe for driving/safety-critical tasks.
LimitsWhen not to use: as OSA diagnosis. · Pitfall: confusing with Epworth (trait sleepiness). · Reassess after naps/caffeine/sedatives.

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| Current sleepiness | 4 — Somewhat foggy / let down |
|---|
→SSS4/7
- Cue：Moderate sleepiness — caution for safety-sensitive tasks
| Current sleepiness | 1 — Feeling active, vital, alert |

→SSS1/7
- Cue：Lower momentary sleepiness

FAQ
Frequently asked questions
- Does Stanford Sleepiness Scale (SSS) upload patient data? Where is it calculated?
- Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
- How is Stanford Sleepiness Scale (SSS) calculated in practice? Can you show a worked example?
- Inputs: Current sleepiness 4 — Somewhat foggy / let down → Result: SSS 4 /7（Cue: Moderate sleepiness — caution for safety-sensitive tasks） Inputs: Current sleepiness 1 — Feeling active, vital, alert → Result: SSS 1 /7（Cue: Lower momentary sleepiness）
