Towards 5G communication systems: Are there health implications?

Area of Science:

• Environmental Health
• Biophysics
• Public Health

Background:

• Radiofrequency electromagnetic fields (RF-EMF) exposure is increasing globally.
• RF-EMF are linked to oxidative stress, a factor in cancer, chronic diseases, and vascular homeostasis.
• The International Agency for Research on Cancer (IARC) classifies RF-EMF as "possible carcinogenic to humans".

Purpose of the Study:

• To review the current understanding of RF-EMF health effects, including emerging 5G millimeter waves (MMW).
• To highlight the need for further independent research on RF-EMF and MMW biological impacts.
• To advocate for the precautionary principle and revision of existing safety limits.

Main Methods:

• Review of existing scientific literature on RF-EMF and MMW health effects.
• Analysis of preliminary findings on MMW impacts on skin temperature, gene expression, and cellular processes.
• Evaluation of evidence linking RF-EMF to various health outcomes.

Main Results:

• RF-EMF are associated with oxidative stress, potential reproductive, metabolic, and neurological effects, and altered antibiotic resistance in bacteria.
• Preliminary MMW data suggest effects on skin temperature, gene expression, cellular proliferation, oxidative stress, inflammation, metabolism, ocular health, and neuromuscular dynamics.
• Existing evidence indicates significant biomedical effects warranting caution.

Conclusions:

• Available data suggest RF-EMF, including MMW, exert biomedical effects and necessitate invoking the precautionary principle.
• Exposed populations should be considered potentially vulnerable, and current exposure limits may require revision.
• Understanding pathophysiological mechanisms is crucial for clinical practice, especially given the role of extrinsic factors in cancer and noncommunicable diseases.
