Why your own
baseline matters.
A useful comparison begins with the circumstances around it.
Illustrative campaign imageryCompare two readings.
A personal baseline is your usual pattern across several readings taken in similar conditions. Choose a situation for each day to see what matches and what changes.
| Condition | Monday | Tuesday |
|---|---|---|
| Time of dayMatches | Morning | Morning |
| ActivityDiffers | Seated at rest | Walking |
| Earbud fitMatches | Usual fit | Usual fit |
Activity differs
Compare seated readings with other seated readings, and walking readings with other walking readings.
Illustrative example of recording conditions.
See what repeats over time.
A baseline tells you what’s usual for you. A profile brings the history of several signals together. In this example, each week uses readings from seated mornings with a consistent earbud fit.
| Signal | Weeks 1–2 | Week 3 | Week 4 |
|---|---|---|---|
| Time between beats | Usual range | Shorter | Shorter |
| Breathing pace | Usual range | Faster pace | Faster pace |
A pattern worth a closer look
Both signals changed together in week 3 and again in week 4. With a longer history, we can study when the pattern repeats and whether one change tends to come first.
The first question is “compared with what?”
A number or a pattern has little meaning without a reference. For a personal wellness experience, the reference should help a person understand what is usual for them, while keeping the circumstances of the observation in view.
Your day changes the setting.
A quiet morning, a moving conversation and a brisk walk are different moments. Fit, activity and surroundings can change what is available to observe. Bringing those details together makes the comparison more understandable.
A pattern opens a conversation.
A personal reference should help people ask better questions about their routines. It should not turn a single observation into a diagnosis. Our developing experience keeps the person, the setting and the limits of the observation in the same picture.
