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 assesses the impact of radio-frequency radiation (RFR) from base transceiver stations (BTS) on human circadian rhythms and sleep behavior. Conducted on 89 healthy individuals randomly selected from a larger pool, the study evaluates how proximity to BTS influences circadian rest-activity rhythms and various sleep parameters.

Findings

• Subjects were divided into groups based on distance from the BTS. Those in the inter-tower and very close proximity (0-150m) experienced higher E-field strengths.
• No significant disruptions were observed in circadian rhythm parameters or behavioral sleep variables across most groups.
• A slight delay in rest-activity peak timings was noted in subjects located in the inter-tower and 300-500m zones.
• Secondary effects related to gender were observed affecting circadian amplitude, sleep efficiency, dichotomy index, and wake time after sleep onset.

Conclusion

While the study found minimal immediate effects on sleep variables, the alterations noted, especially in specific proximity groups and gender differences, highlight potential underlying risks of RFR exposure. The authors advocate for more comprehensive future studies to ascertain the broader impacts of BTS radiation exposure on human health.
