If your lowest nightly heart rate goes up that’s a sign that you are doing something that stresses your body. People who get a COVID-19 vaccine for example usually report that their lowest rate rate goes up in the night. The same goes for getting ill or being stressed at work.
For heart rate variance higher numbers are better and indicate that the body is less stressed. People with burnout have very low heart rate variance.
If you would observe that additional sleep increases your lowest nightly heart rate and reduces your heart rate variance that’s a sign that your body recovers less well in the night.
Besides cognitive measures, measures of stress such as the lowest night time heart rate and heart rate variance are good metrics to track.
Thanks but that requires better model of how humans function than I have. It’s not obvious to me how to interpret those metrics.
They are metrics of whether people are stressed.
