Heart Rate Variability (HRV)

Heart Rate Variability is where the amount of time between your heartbeats fluctuates slightly. Even though these fluctuations are undetectable except with specialized devices, they can still indicate current or future health problems, including heart conditions and mental health issues like anxiety and depression.

HRV is typically measured in milliseconds (ms) using an electrocardiogram (ECG) or a heart rate monitor. The time intervals between heartbeats (R-R intervals) are analyzed to calculate the average HRV and other metrics. 

HRV is considered an important indicator of cardiovascular health and overall well-being. Higher HRV generally indicates: 

• Good autonomic nervous system function:

  The ANS is able to adapt to changes in the environment and maintain a balance between the "fight-or-flight" (sympathetic) and "rest-and-digest" (parasympathetic) systems. 

• Reduced stress levels:

  HRV decreases during stress, so higher HRV suggests better stress resilience. 

• Improved cardiovascular fitness:

  HRV is associated with lower risk of cardiovascular diseases, such as heart attacks and strokes.
