Quick Answer (TL;DR)
Resting heart rate is how many times your heart beats per minute at rest. For most adults, 60 to 100 beats per minute is considered normal.
What It Means
Fitter people often sit in the 50s or lower, which is usually a good sign. What matters most is your own baseline and any lasting change from it.
Why It Matters for Your Health
A resting rate that drifts upward over weeks can reflect illness, dehydration, stress, poor sleep, thyroid problems or anaemia, so it works well as a general early-warning number.
Recommended Biomarker or Metric to Track
Log your resting rate each morning before getting out of bed.
