Original Findings Confirmed in Replication Study: Provocation with 2.4 GHz Cordless Phone affects Autonomic Nervous System as measured by Heart Rate Variability

Abstract

Overview

This study is a double-blind, placebo-controlled replication aimed at analyzing the impacts of 2.4 GHz cordless phone radiation on heart rate variability (HRV). Employing orthostatic testing, the study aimed to evaluate adrenal function and assess responses to stressors in subjects.

Findings

• Out of 69 subjects, responses varied with some showing severe reactions indicative of stress responses.
• 7% of subjects were classified as “moderately to very sensitive” to electromagnetic fields.
• Documentation of a delayed response to electromagnetic radiation, with novel findings in heart rate variability.

Conclusion

The study confirms the sensitivity of certain individuals to non-ionizing radiation from cordless phones, affecting autonomic nervous system responses and potentially increasing heart risk in susceptible individuals. Further research is needed to fully understand the complexities of electrohypersensitivity (EHS).
