KnowYourPrime evidence rating Emerging Evidence currently favors the claim, but more confirmation is needed. Groups of workers reporting more job stress tend to have lower HRV, and HRV drops during stressful work periods compared with recovery, but the one study that followed the same people through a working day did not find job demands lowering HRV. The link supports statements about groups, not predictions about one person. Finding KYP-ER-0006 Version 1.0 Reviewed October 24, 2026 Rating rule 1.6 [CC BY 4.0](https://creativecommons.org/licenses/by/4.0/) ## Why this is rated Emerging This is the evidence beneath every claim that a wearable can detect or prevent burnout. Two independent reviews affirm the link: one across job-strain studies comparing workers, one within doctors comparing their own stress and recovery periods. A null result sits against it. Teachers rating their job demands six times a day showed the effect on exhaustion and not on HRV. With two affirming anchors and a core-hitting null, the rule rates the claim Emerging rather than Established. How the rating rule reads this evidence - Systematic-review or meta-analytic evidence affirms the core relationship. - Multiple supporting studies are consistent with the core relationship. - Null-result evidence bears directly on the claimed effect. ## Key results - A systematic review of 10 studies found higher occupational stress associated with lower HRV, mainly reduced parasympathetic activity; 9 of the 10 studies were cross-sectional, so the direction is not established. (Järvelin-Pasanen et al., Industrial Health, 2019) - In a meta-analysis of continuous HRV monitoring in doctors, RMSSD was lower during stress than recovery (standardized mean difference -0.63) and SDNN lower (-1.05), in studies of 12 to 54 participants rated moderate quality at best. (Kane et al., Occupational Medicine, 2026) - Across 669 ambulatory measurements in teachers, job demands affected emotional exhaustion but not state HRV. (Schmid et al., Anxiety, Stress, and Coping, 2021) ## What this finding covers **Applies to:** The association between occupational stress and HRV in working adults, measured between people and within people across work and recovery. **Does not cover:** Whether any wearable or vendor score can predict or prevent burnout in an individual, which no study scored here validates; workplace wellness program outcomes. ## Limitations - Most studies compare groups at one point in time, which cannot show that stress causes lower HRV. - Studies used different HRV devices and stress questionnaires. - Much of the within-person evidence comes from doctors and surgeons, not general workforces. ## Evidence base 6 studies scored · 2 anchor · 1 null · 3 supporting · Evidence last evaluated Oct 24, 2026 ### Anchor studies The studies the rating rests on. 1.
