Mental Stress Management Using fNIRS Directed Connectivity and Audio Stimulation
Summary
This study shows 16 Hz binaural beats auditory stimulation (BBs) effectively reduces workplace stress and boosts cognitive vigilance. BBs improved accuracy and reduced stress markers, enhancing prefrontal cortex connectivity.
Area of Science:
- Neuroscience
- Cognitive Psychology
- Occupational Health
Background:
- Workplace stress negatively impacts cognitive function and well-being.
- Cognitive vigilance is crucial for task performance and safety.
- Developing effective, non-invasive methods to mitigate stress and enhance vigilance is essential.
Purpose of the Study:
- To investigate the efficacy of 16 Hz binaural beats auditory stimulation (BBs) in mitigating mental stress.
- To assess the impact of BBs on cognitive vigilance.
- To explore the neurophysiological mechanisms underlying stress and BBs' effects.
Main Methods:
- Inducing stress using the Stroop Color-Word Task (SCWT) under time constraints and negative feedback.
- Administering 10-minute sessions of 16 Hz BBs.
- Measuring stress levels using functional Near-Infrared Spectroscopy (fNIRS), salivary alpha-amylase, reaction time (RT), and target detection accuracy.
Main Results:
- 16 Hz BBs significantly increased target detection accuracy by 21.83% (p < 0.001).
- Salivary alpha-amylase levels, a stress biomarker, decreased by 30.28% (p < 0.01).
- Neuroimaging analyses revealed BBs enhanced prefrontal cortex connectivity, particularly in the dorsolateral and left ventrolateral regions.
Conclusions:
- 16 Hz BBs serve as an effective intervention for mitigating workplace mental stress.
- BBs demonstrably enhance cognitive vigilance and improve neural network function.
- The findings support the use of BBs as a tool for improving employee well-being and cognitive performance.

Stress often leads to unhealthy habits like smoking, excessive drinking, and overeating, which offer short-term relief but ultimately increase long-term health risks. These behaviors create a cycle that temporarily lowers stress levels but can result in severe long-term health consequences. Breaking these habits is essential to reduce the risk of chronic diseases and improve overall well-being. Three primary changes that support better health include quitting smoking, reducing alcohol intake,...

A social support system is a structured network of personal relationships that provides assistance to individuals facing various challenges, offering a buffer against psychological and physical stressors. This network may consist of family members, friends, neighbors, colleagues, or other community members who provide resources and companionship. Social support can take many forms, including advice, emotional comfort, practical help, and companionship. Research indicates that these networks can...

Regular exercise and meditation serve as essential tools in managing stress and promoting physical and mental well-being.
The Role of Exercise in Stress Management
Regular physical activity is essential for reducing stress and promoting cardiovascular health. Exercise strengthens the heart, enhances blood flow, keeps blood vessels flexible, and helps lower blood pressure, all of which reduce the body's stress response. Research shows that adults who exercise regularly have nearly half the...
