Area of Science:

  • Neuroscience
  • Human Physiology
  • Public Health

Background:

  • Mask-wearing became widespread during the COVID-19 pandemic as a public health measure.
  • The neurological effects of prolonged mask usage remain largely uninvestigated.

Purpose of the Study:

  • To examine the impact of extended mask use on human brain activity using electroencephalogram (EEG).
  • To assess cognitive performance and physiological parameters during mask-wearing.

Main Methods:

  • 10 subjects performed a cognitive task with and without masks.
  • EEG recorded neural activity; physiological data (oxygen saturation, heart rate, blood pressure, temperature) were also collected.
  • Spectral analysis and linear discriminant analysis (LDA) were applied to EEG data.

Main Results:

  • Masked subjects showed significantly lower EEG spectral power in alpha, beta, and gamma bands.
  • Task performance and oxygen saturation levels were significantly reduced in the masked group (p < 0.05).
  • Occipital (O1, O2) and frontal (F3, AF3, F7) brain regions showed significant variations in neural activity.

Conclusions:

  • Prolonged mask usage can alter human brain activity, particularly in frontal and occipital lobes.
  • Reduced neural activity and cognitive performance are associated with mask-wearing.
  • Further research is needed to understand long-term implications of mask mandates on cognitive function.
