Abstract

Overview

This study investigates the effects of electromagnetic radiation (EMR) from the wireless signal range on mice. Recent decades have seen a significant increase in environmental EMR, yet its impact on living organisms is not well understood.

Findings

  • Exposure to 2.4-GHz EMR modulated by 100-Hz square pulses resulted in a marked increase in the time mice remained awake.
  • This increase in wakefulness corresponds with decreased time in nonrapid eye movement (NREM) and rapid eye movement (REM) sleep stages.
  • Conversely, unmodulated 2.4-GHz EMR exposure did not significantly alter sleep architecture.

Conclusion

These results suggest a specific physiological response in mice to prolonged exposure to modulated wireless-range EMR, highlighting potential concerns for similar exposure in humans. Further exploration into different modulation functions and frequencies is recommended to fully understand this phenomenon.
