Salivary neuropeptides including oxytocin and beta-endorphin increase synchronously during acute stress training and stay elevated into recovery.
Pairwise correlations exceeded 0.9 across baseline oxytocin, neurotensin, and substance p, while composite scores tracked self-assessed hardiness.
Assessment across three training timepoints evaluated the acute stress response, highlighting potential neuroimmune targets to enhance occupational resilience.
