Contributions to nursing, health, or public policies
On the other hand, this RCT represents advances for workers’ health and for nursing, since this study proposed a more robust methodology, aiming to verify the effect of an intervention on an outcome. Using HRV CBKF brought two strengths: encouraging self-regulation, involving workers in seeking an expected result through goals for prevention and health maintenance, and providing the measurement of a phenomenon in a non-invasive way. The results found brought a great contribution to nursing by demonstrating that HRV CBKF can improve autonomic regulation, minimizing the symptoms of chronic stress.
