Experts from Mount Sinai, Kiel University and Puget Sound say wearable-tracked millisecond heartbeat changes can guide recovery, with average scores around 65 for men and 62 for women.
Higher variability generally signals better nervous-system flexibility, while persistently low readings are linked in studies to anxiety, depression, PTSD and possible cardiovascular problems including atrial fibrillation.
Researchers say trends over time matter more than single readings, chest straps can outperform wrist devices, and breathwork may improve scores, though evidence remains mixed and standardisation is limited.
Can chasing a high HRV score become a new source of stress, harming the nervous system you are trying to heal?
As AI predicts depression from HRV, what are the ethical lines between helpful insight and digital mental health surveillance?
