# Does inactivity\_seconds include sleep?

For providers that don't report inactive time directly (like Garmin), `inactivity_seconds` is computed as **24 hours minus active time**. So it includes sleep and is **not** a sedentary-time metric.

For sedentary behaviour, use the more granular `activity_levels_samples` instead, since most wearable APIs don't expose a dedicated sedentary-minutes field.
