Does exposure to radiofrequency radiation (RFR) affect the circadian rhythm of rest-activity patterns and behavioral sleep variables in humans?

Abstract

Overview

This exploratory field study investigates the impact of radio-frequency radiation (RFR) from base transceiver stations (BTS) on human circadian rhythms and sleep behaviors.

Methodology

• Study Design: A sample of 89 healthy subjects, randomly selected from 1434 surveyed, was divided into five groups based on their proximity to the BTS.
• Measurements: Circadian rest-activity rhythms and various sleep variables were analyzed, focusing on differences by group location and E-field strength.

Findings

Higher E-field strengths were observed closer to the BTS, especially between 0 and 150 meters and in inter-tower areas. These conditions led to:

• A marginal delay in the peak timings of rest-activity rhythms in certain groups.
• Gender-specific secondary effects on circadian amplitude, sleep efficiency, dichotomy index, and wake after sleep onset.

Conclusion

The study revealed only marginal influences of RFR on circadian and sleep parameters among groups differing by their nearness to BTS. However, the presence of secondary gender-specific effects suggests a potential under-examined area of concern. Further extensive, rigorous studies are encouraged to more fully understand the impacts of BTS radiation on human health.
