Heart rate, the number of times the ventricles of the heart contract and relax (that is, beat) per minute or other unit of time. In human beings, the normal resting heart rate among adults ranges from 60 to 100 beats per minute (BPM), whereas the normal
Bradycardia is a slow heart rate -- fewer than 60 bpm. Your resting heart rate typically drops below 60 bpm when you're sleeping. Some athletes and young adults can have heart rates of 40-60 bpm as well. More seriously, bradycardia results from your heart being unable to pump well enough...
though individuals who are overweight or obese may have a higher heart rate while sleeping due to poorer cardiovascular efficiency and a larger amount of body tissue to oxygenate relative to the size of the heart.

[67] found a significant relationship between reduced sleep quality and lower RMSSD and heart rate during sleep. Regarding 24 h HRV, significant negative correlations were reported between sleep quality and HRV [66,69] and positive correlations were reported between sleep quality and mean heart ...
Your heart rate generally decreases while you sleep. If you notice that it increases during sleep, it can signalsleep apneaor another underlying cause. If a problem like a dangerous arrhythmia is causing a high heart rate, it can be fatal—and possibly occur without warning. ...
Because heart rate variability is specific to each individual, giving a specific number of recommended beats per minute is difficult. Generally, your heart rate while sleeping should be 20 to 30 percent below your resting heart rate during the day. As you measure your HRV over time, you should...
While it generally holds that the lower your heart rate, the better, recent studies suggest that there is enormous variability in the average resting heart rate from person to person. This means that you shouldn't worry too much if you are far from the average resting heart rate of 65.6±...
HRV is an extremely sensitive metric that varies greatly throughout the day. Tracking it 24/7 (or any time when you're active) is not very useful because it fluctuates drastically from one moment to the next. Even changes in yourrespiratory ratewhile you’re sleeping can have a significant...
