For me, on most days the difference between an RHR value at sleep versus just being awake is only about 2-3bpm – so not enough to be of major concern.But if it’s 10bpm due to data gathering wonkiness, then that’s more problematic.However, some of those were cumbersome, and all required extra effort (which, let’s be honest, none of us wanted to do upon waking up).So, data was often somewhat variable and inconsistent day to day.But wait a second you ask – how does a unit differentiate between sleep and non-sleep rest? Consider just lying around when you wake up and looking at your actual HR using the device, and then later in the day validate that the value shown on the app for RHR is your lowest HR value while awake.Remembering that you usually want to lie down for 2-4 minutes to let things calm a bit.For me, the most valuable use case of the data is around fatigue and predicting some sickness.For example, my resting HR is usually in the 39-42bpm range.
No longer are you limited to just workout HR data, but now you can get it while you eat, sleep and work (and practice Valentine’s Day). And in many ways, they continue to be the company that does 24×7 data gathering the best (now with the newer Basis Peak).
Now technically speaking, per most medical definitions of this, it’s actually your lowest heart rate while awake.
Typically you’ll see slightly lower heart rates while sleeping.
For example, if you confer with the American Heart Association, they note that RHR should be measured while sitting or lying:“Your resting heart rate is the heart pumping the lowest amount of blood you need because you’re not exercising…Resting, sitting or standing, your pulse is usually the same.
Sometimes as you stand for the first 15 to 20 seconds, your pulse may go up a little bit, but after a couple of minutes it should settle down.”Most devices on the market today can automatically detect your RHR and display it to you within the app or even on the device itself.
