Ubiquitous extremely low frequency electromagnetic fields induces anxiety-like behavior: mechanistic perspectives

Overview

Anxiety is an adaptive condition marked by heightened uneasiness, which, when persistent, can lead to reduced quality of life and impact both mental and physical health. Increasing concerns have been raised about the dangers of extremely low frequency electromagnetic fields (ELF-EMF; 3–3000 Hz), which are present ubiquitously in our daily environment. Research has begun to uncover the anxiogenic (anxiety-inducing) effects of ELF-EMF exposure.

Findings

• Studies show that ELF-EMF can impact various brain regions, notably the hippocampus, a key area involved in anxiety regulation.
• ELF-EMF exposure interferes with the hippocampus-prefrontal cortex pathway, which can lead to anxiety-like behavior.
• Such exposure can induce oxidative stress within the hypothalamus and hippocampus, further contributing to anxiety behavior.
• ELF-EMF may reduce neuroplasticity and increase NMDA2A receptor expression within the hippocampus, both mechanisms linked to increased anxiety.
• Antioxidant supplementation is proposed as a potential protective measure against ELF-EMF-induced anxiety behavior.

Conclusion

• ELF-EMF causes oxidative stress in brain regions associated with anxiety, resulting in elevated stress hormone levels and heightened neural excitability.
• Decreased neuroplasticity and receptor modulation in the hippocampus due to ELF-EMF exposure may play a critical role in triggering anxiety behavior.
