Heart rate variability describes variation in the intervals between heartbeats. Wearables have made it easy for executives to encounter an HRV score each morning, often with a simple instruction about readiness.
The score needs more context than its presentation may suggest.
Know what is being measured
Readings depend on the device, measurement conditions and the person. Changes can reflect several influences, including activity, sleep, illness and other factors. A population comparison is not the same as a meaningful change from a stable personal pattern.

Research can examine associations between HRV and aspects of functioning. That does not make a consumer reading a direct measure of executive judgment or a verdict on whether a decision should proceed.
Use the information proportionately
If you track HRV, keep the measurement conditions reasonably consistent and consider it alongside other observations. Notice patterns rather than treating one low score as an explanation for the day.
Do not use the score to diagnose a health problem or to overrule appropriate medical advice. Equally, a favorable reading does not compensate for missing information in a business proposal.
For a decision, check the preparation, alternatives and authority directly. A wearable may prompt a useful question about rest or health; it cannot answer the commercial question the executive has been asked to settle.
