Exploring the potential effects of different frequencies of flashing light stimulation on alleviating mental fatigue: a behavioral and EEG study

Flashing light stimulation at 20-30 Hz frequencies effectively alleviates mental fatigue and enhances alertness. These findings suggest that broader frequency-band light stimulation could offer a more effective method for reducing mental fatigue compared to single-frequency stimulation. Further research is needed to investigate the optimal parameters for light stimulation and its potential applications in clinical and everyday settings.
