Unpacking the Science of Electromagnetic Sensitivity

by Jon Scaccia March 27, 2025

In the Breaking Bad prequel series Better Call Saul, Jimmy McGill’s (a.k.a. Saul Goodman) older brother has isolated himself due to a perceived electromagnetic sensitivity.

In a world dominated by screens, Wi-Fi signals, and 5G towers, concerns about electromagnetic fields (EMFs) have grown. For some individuals like Chuck McGill (above), these concerns go beyond curiosity or skepticism—they report experiencing severe symptoms they attribute to EMF exposure. These individuals often take drastic steps to limit their exposure, but a recent study from Belgium suggests that avoidance strategies might not be the answer.

If avoiding EMFs doesn’t reduce perceived exposure, what’s really happening? And what does this mean for public health practitioners, researchers, and individuals struggling with these symptoms?

The Research: Exploring Electromagnetic Sensitivity

This study surveyed 382 participants in Belgium during two phases of COVID-19 lockdowns (June/July 2020 and February/March 2021). Researchers wanted to understand three key questions:

1. Do people who identify as EMF-sensitive report greater worries about modern health issues?
2. Do they engage in more avoidance behaviors to reduce EMF exposure?
3. Do those avoidance behaviors actually reduce their perception of exposure?

Key Findings: Fear, Avoidance, and Exposure Perception

1. EMF Sensitivity and Health Worries Go Hand-in-Hand

People who identified as highly sensitive to EMFs reported significantly greater concerns about modern health issues. These concerns extended beyond EMFs to include pesticides, air pollution, and antibiotic overuse. This suggests that EMF sensitivity might not be an isolated phenomenon but part of a broader pattern of health-related anxieties.

2. Avoidance Strategies Are Common—but Not Effective

The study found that EMF-sensitive individuals frequently engaged in avoidance behaviors. Some of the most common strategies included:

• Reducing or eliminating RF device usage
• Seeking “EMF-free” environments to recharge
• Avoiding locations perceived as high in EMF exposure

However, despite taking these measures, participants still felt highly exposed. This contradicts the idea that avoidance leads to relief, raising questions about whether these strategies are truly beneficial.

3. Perceived Exposure Remains High, Even with Avoidance

Logically, if someone avoids an environmental factor, their perception of exposure should decrease. But the study found the opposite—individuals who adopted more avoidance behaviors continued to report high levels of exposure.

Why? The researchers propose several explanations:

• Increased Awareness: Actively avoiding EMFs may make people more conscious of their presence.
• Ineffective Avoidance: Because EMFs are virtually everywhere in modern society, partial avoidance doesn’t eliminate exposure.
• Psychological Conditioning: The more someone believes EMFs are harmful, the more they may attribute symptoms to exposure, regardless of actual EMF levels.
• Nocebo Effect: Just as placebos can improve health, negative expectations can worsen symptoms.

What This Means for Public Health

The findings highlight a paradox: individuals who report high EMF sensitivity try to avoid exposure, yet continue to feel highly exposed and distressed. This suggests that traditional avoidance strategies might not be the best approach.

So, what should public health professionals and healthcare providers consider?

• Rethinking Treatment Approaches: Rather than encouraging avoidance, interventions should focus on managing health anxieties and addressing underlying concerns. Cognitive-behavioral therapy (CBT) has shown promise in helping individuals cope with perceived environmental sensitivities.
• Addressing the Nocebo Effect: Public health messaging should be clear and evidence-based, countering misinformation while acknowledging individuals’ distress.
• Exploring Alternative Support Strategies: Helping individuals regain a sense of control—whether through stress management techniques or addressing broader health concerns—may be more effective than avoidance.

What’s Next? The Future of EMF Sensitivity Research

While this study provides valuable insights, many questions remain. Future research should:

• Investigate long-term patterns in EMF sensitivity and avoidance behaviors.
• Explore how interventions like CBT could help individuals reduce distress.
• Examine the role of misinformation and public perception in shaping EMF-related concerns.

As 5G networks expand and digital connectivity deepens, EMF sensitivity will likely remain a topic of debate. Understanding the psychological and social dimensions of this issue is crucial for developing compassionate and effective public health strategies.
