Open health data
Free, plain-English reference ranges for how much people sleep, how many steps they take, healthy weight by height, resting heart rate and more — free to cite and embed.
These are illustrative, rounded reference ranges for general guidance — not precise national statistics or medical advice. Each dataset says where its figures come from.
Why an open data hub
Simple questions — how much sleep do I need, how many steps is enough, what is a healthy weight for my height — are surprisingly hard to answer without wading through jargon. This hub gives the honest, well-established range for each, in plain language, on a page you can cite or embed for free.
Every figure here is a rounded consensus band rather than a single precise number, because a range is both more honest and more useful: a healthy adult might need seven hours of sleep or nine, and both are normal. Where real measured averages vary by country or year, the dataset page says so.
Datasets
How much sleep people need by age
Consensus sleep-duration ranges from newborns to older adults — most adults land at 7–9 hours.
Average daily step counts
What counts as sedentary, active and highly active — and why 10,000 steps is a target, not a medical threshold.
Healthy weight range by height
The weight band for a healthy BMI (18.5–24.9) at each height — more useful than a single "average" weight.
Resting heart rate by fitness
The normal adult range is 60–100 beats per minute; fitter hearts tend to beat slower at rest.
Typical bedtimes and wake times
When people actually go to bed and wake — and why teenagers run naturally later.
Average adult height
Typical adult-height bands by sex, and why a global "average" is only a rough guide.

Frequently asked questions
Can I cite or reuse these figures?
Yes. Everything here is free to quote, cite and embed, with a link back to the dataset page. The figures are rounded, illustrative ranges drawn from public consensus guidance, not a proprietary survey.
How accurate are the numbers?
They are honest order-of-magnitude ranges, not precise national statistics. Each dataset explains where its band comes from and where real measured values vary. Treat them as a starting point, then check a primary source for exact figures.
Are these medical advice?
No. They are general reference information. Individual needs vary, and anything about your own health should be discussed with a clinician.
Your own numbers, tracked
TempoLife logs your sleep, steps and weight and shows how you compare with the healthy ranges over time.
