This systematic review and meta-analysis explored how psychosocial stress affects brain activity, focusing on EEG (electroencephalogram) measures like alpha and beta power and frontal alpha asymmetry (FAA). Psychosocial stress consistently reduced alpha power, indicating heightened cortical activity. Beta power and FAA showed inconsistent patterns across stress phases (anticipation, reaction, recovery). The findings emphasize the complexity of the brain's response to stress and suggest that alpha power may be a reliable marker for stress. These insights are valuable for understanding the neurological impact of stress and for developing stress-management interventions.
To manage stress's neurological effects, incorporate relaxation practices such as mindfulness, yoga, or biofeedback, which may help regulate brain activity associated with stress. These interventions are supported by alpha power reduction findings, though inconsistencies in other measures highlight the need for personalized approaches. Future research will clarify the optimal strategies for different stress phases.
