Resting heart rate over time.

What resting heart rate is

Resting heart rate is the number of heartbeats per minute while you sit or lie still. Watches and rings usually work it out themselves: from periods when you were still for a while, sometimes also from the night. Apple Health calls it “Resting Heart Rate”; other apps use names like “resting HR”.

Because it is measured at rest, it is less affected by what you happen to be doing than your heart rate across the day. That makes it well suited for seeing changes over days and weeks.

Why it varies

From day to day, resting heart rate moves by a few beats. Many people see changes after short nights, after intense training days, in hot weather, after a late evening or while travelling. The measurement itself varies too: how well the watch fits and how many quiet phases there were both play a part.

Single outliers are therefore part of the picture. It gets interesting when a value moves in one direction over several days – or when a pattern repeats, for instance after certain weekdays.

Your usual range

Reference values from tables are of little help in everyday life: typical resting heart rate differs a lot between people, and devices measure differently too. More telling is your own usual range – the range your value was in over the last four weeks.

Instead of “good” or “bad”, it then reads “within your usual range”, “above” or “below”. That is a description, not a judgement and not a statement about a cause.

Devices and measurement

Values from different devices are not directly comparable. Switching watches often shows up as a jump in your history even though nothing else changed. It helps to stay with one source where possible and, after a switch, to wait a few weeks until your usual range has formed again.

Where to find your values and how to choose the source is explained in the guides on Apple Health and Health Connect.

How mypacing shows resting heart rate

In the daily picture, resting heart rate is one of three recovery signals, alongside HRV and sleep. Each is compared with your usual range over the last four weeks and described in a full sentence, such as: “Your resting heart rate is above your usual range today.” In your history, the usual range appears as a band in the chart.

mypacing is not a medical device: the app does not make diagnoses and gives no recommendations; it shows your values clearly.
