Abstract
Escalating stress prevalence, particularly among essential service personnel whose cognitive compromise threatens public welfare, necessitates rapid, accessible non-pharmacological interventions. Individuals who struggle with endogenous cultivation of beneficial neuropsychological states may benefit from passive exogenous stimulation. This uncontrolled exploratory investigation (n = 74) evaluated single-session rhythmic audiovisual stimulation protocols delivered within an immersive reflective chamber (MindGym), wherein employed individuals with self-reported high-stress received randomized assignment to alpha (9-11 Hz) or theta (4-7 Hz) conditions, the sole intervention difference being stimulation frequency of synchronized stroboscopic light and binaural beats during an 11.5-min exposure. Both protocols were well-tolerated and associated with substantial acute improvements in anxiety, mood disturbance, flow states, and vitality, alongside moderate enhancements in perceived stress and purpose in life. No between-protocol differences emerged, though baseline mood disturbance predicted preferential theta-enhancement of existential purpose. Neurophysiological entrainment evidence was inconclusive given consumer-grade instrumentation. These findings establish feasibility warranting controlled trials with active comparisons and follow-up.
