Researchers have used mathematical analysis tools to study the effect of classical music on a fetal heartbeat and identify patterns in heart rate variability. They recruited 36 pregnant women and ...

Heart rate variability (HRV) is the variation in the time between two consecutive heartbeats over a specific period. Doctors may use HRV as an indicator for certain aspects of a person’s health, ...

Heart rate variability typically decreases during stressful situations, although the heart rate increases. Managing stress levels can mean a more variable heart rate. Exercise and relaxation ...

Wearables measure several aspects of health, and heart rate variability might be one of those. It may be surprising when your device informs you that your heart rate variability is high or low, but ...

Micro-fluctuations in the time between heartbeats are proving a helpful indicator of mental health, stress levels and exercise capacity. They could even provide insight into how well you are ageing.

Playing music has long been a way for expectant parents to connect with their children in the womb, but a group of researchers has found evidence it can calm fetal heart rates, potentially providing ...
