Abstract

Abstract

Overview

Electromagnetic radiation (EMR) in the environment has surged in recent decades, raising significant concerns about its effects on health.

Findings

  • Prolonged exposure to 2.4-GHz EMR, modulated by 100-Hz square pulses at a nonthermal output level, results in a significant increase in wakefulness among mice.
  • This increase in wakefulness is accompanied by a decrease in both nonrapid eye movement (NREM) and rapid eye movement (REM) sleep phases.
  • In contrast, exposure to unmodulated 2.4-GHz EMR at the same output level does not noticeably affect mouse sleep patterns.

Conclusion

The study indicates a distinct physiological response in sleep architecture due to prolonged exposure to modulated wireless-range EMR, highlighting potential health risks associated with environmental EMR exposure.
