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...
What Is Your Sleeping Heart Rate? Nightly averageRHRvaries widely between individuals. A normal heart rate can range anywhere from 40 to 100 beats per minute (BPM) and still be considered average. It can also change from day to day, depending on your hydration level, elevation, physical acti...

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...
They found that core body temperature drops >0.7 [°C] in a 17 [°C] sleeping environment, with even greater drops in lower temperature conditions. The same may apply to day-to-day fluctuations where the operative temperature around the head significantly affects the core body temperature. It...
Even changes in your respiratory rate while you’re sleeping can have a significant impact on your heart rate variability. In order to get a consistent and reliable HRV measurement, WHOOP calculates your heart rate variability using a dynamic average during sleep. It is weighted towards your last...
If your HRV drops, it means that some reasons have affected you, such as excessive work pressure, mood swings and not sleeping well. In addition, smoking, drinking and some drugs are also likely to reduce HRV. If you have a continuous sharp drop in HRV, it may be a pre disease, which...
Unstable angina occurs at rest or while sleeping, when one would expect that the work the heart might be expected to do would be minimal. Episodes of angina are never normal and need to be reported to and evaluated by a health care provider promptly. ...
