Key result
Smoking, insomnia, and job insecurity among live fire instructors were associated with decreased heart rate variability.
Why the study?
This study aimed to identify the association between health-related characteristics, occupational stress subscales, and heart rate variability in live fire instructors.

Are health behaviors and occupational stress associated with heart rate variability in live fire instructors?
Insomnia, smoking, and job insecurity are associated with decreased heart rate variability among live fire instructors.
Answers are grounded in this paper and cite their sources.
Should not yet change practice; hypothesis-generating for occupational effects on HRV.
OBJECTIVES: This study aimed to identify the association between the healthrelated characteristics and the subscales of occupational stress of live fire instructors and heart rate variability (HRV). METHODS: We conducted questionnaire survey on a general health checkup for 15 live fire instructors. Occupational stress and HRV parameters were measured to determine the association between health behavior, including smoking, drinking, exercise, and sleep-related disorders, and occupational stress of live fire instructors and HRV parameters using Spearman's rank correlation coefficient. RESULTS: Smoking, insomnia, and job insecurity, a subscale of occupational stress measurement, showed negative Spearman rank correlations with HRV. CONCLUSIONS: Insomnia, smoking, and job insecurity (due to occupational stress) among live fire instructors were associated with decreased HRV.

Shin et al. (2022) conducted a cross-sectional in Occupational stress (n=15). Occupational stress and health behaviors (smoking, insomnia, job insecurity) was evaluated on Heart rate variability (HRV). Smoking, insomnia, and job insecurity among live fire instructors were associated with decreased heart rate variability.
