Can HRV (Heart Rate Variability) Measure Stress?

How does the body react to stress or anxiety? Your heart’s movements represent both physical and mental stress, which is why the variability of the heart rate (HRV) is an important indicator.

 

You have an autonomous nervous system (ANS) that regulates your heart. Your heart under stress: The rest-and-digest part of the ANS blocks the portion that continuously governs fight or flight under relaxed circumstances. As anxiety begins, it eases the brakes to stabilize and brace the body for the fight or flight phase’s stressor.

 

The Fight or flight mechanism

 

Your fight or flight mechanism allows resource reallocation to prepare the body for battle. Think of it as if your ANS is adding resources in certain places (for example, your muscles) while maintaining them minimally in other areas (for example, your digestion) when faced with risk.

 

Your fight or flight device inside your heart stimulates the heart like a metronome to beat more steadily so that your ANS can restructure resources elsewhere. Its triggering increases the heart rate but reduces beats (the HRV) variation.

 

Your system uses energy to control the functions of the body. It reduces your heart rate level and increases your HRV. It can be flexible and can change from one beat because the heart does not have to pound rapidly to pump blood into your body.

 

Stress decreases HRV, and relaxation increases HRV.

 

A persistent physical or psychological stress cycle puts you at risk for injuries, well-being, and prolonged fatigue. Patterns of payment Focus HRV is a device to warn you that activity/reconciliation is unbalanced.

 

Generally, higher HRV is an indication that the activation and resting processes are more stable and autonomous. If you find that your HRV is small compared to your baseline, your battle or flight system would possibly overdrive and push your body at an excessive speed. Mentally, hormonally or biologically, you are paid.

 

In daylight or stress or anxiety in the HRV, play with ways to change the balance to relax or monitor many day-to-day stressors.
