Questions you can finally answer

Your Apple Watch knows.
Why shouldn't you?

Why have I been so tired lately?

Your sleep has averaged 5.8 hours over the last two weeks — down from about 7 the month before.

That alone would explain feeling run down. Nothing here looks alarming — your body is just short on rest.

Try protecting an earlier bedtime for a few nights. Even one extra hour tends to make a real difference.

Explains how you feel, in plain English

Is my heart doing okay?

From what your watch records, yes. Your resting heart rate has been steady around 61 bpm, comfortably in a healthy range, and it barely moves day to day.

A calm, consistent resting heart rate is usually a quiet good sign.

Reassurance, grounded in your numbers

Have I been active enough?

You've been out walking most days this month, a little more on weekends — that's a solid, steady habit.

There's no quota to hit. If you wanted a gentle nudge, one more short walk on the quieter days would round the week out nicely.

Encouraging, never judging
