Wireless radiation and the brain

October 16, 2023

Did you know that your brain is the organ of your body that is most sensitive to radiofrequency (wireless) radiation? And chances are it’s being bombarded by exposure every single day.

How does this exposure affect the brain and should we be concerned?

To answer these and other questions, a team of researchers from Korea reviewed the relevant research and made some interesting observations.

‘Humans are swimming … in a vast ocean of different radiations in this environment, resulting in frequent exposure,’ the authors wrote. This radiation is known to affect biological systems from microbes to animals and humans and how it affects them depends on the characteristics of the signal, such as frequency, power and length of exposure.

In some cases, the effects can be therapeutic, the authors pointed out. For example, some very high frequency millimetre waves (such as 101 GHz) have been used to successfully treat various diseases, including cancer.

However, in many cases, the effects can be harmful.

For example, wireless radiation has been found to have harmful effects on the male reproductive system, including:

  • inflammation
  • testicular impairment
  • sperm
  • testosterone
  • and DNA fragmentation.

However, it’s the central nervous system (CNS) that’s most affected by exposure, especially the hippocampus. ‘Specifically, microwaves can damage the brain (one of the two key components of the human CNS), particularly affecting the neurotransmitters which play an important role in passing signals inside the body,’ the authors wrote. ‘Accordingly, microwave-induced injury to neurotransmitters can cause a delay in the signaling process, which has critical implications for body function.’

Among the harmful effects on the CNS that the authors identified were:

  • DNA damage
  • oxidative stress
  • effects on structure of hippocampus causing behavioural changes (eg anxiety)
  • reduced memory and learning
  • changes to calcium influx
  • changed antioxidant enzymes
  • and possibly CNS diseases such as Alzheimers.

While pointing out that not all radiofrequency signals are harmful, the authors nevertheless recommend that protective techniques be developed to overcome ‘the potentially harmful effects of ever-increasing doses of radiation’.

‘[M]icrowave radiation can modulate responses in the CNS, where higher doses can produce ROS, oxidative stress, and neuroinflammation. Treatment with natural products is, thus, necessary to reduce these harmful effects, they say.

One of these is the use of flavonoids, beneficial compounds that are found in fruits and vegetables. ‘Flavonoids represent one such group of plant-derived compounds displaying important radioprotective and neuroprotective properties while reducing DNA damage and inflammation within the CNS; thus, flavonoid treatment may be an important and promising therapeutic alternative for avoiding radiotherapy-induced pathophysiological alterations in the brain, as well as cognitive impairment.'

It's food for thought.
