What are our bacteria trying to tell us?

What have WiFi, 5G and the bacteria that are probably on your skin and in your nose got to do with each other?

Believe it or not, they all emit radiofrequency radiation.

A recent US study discovered that Staphylococcus aureus bacteria – which are commonly found on the skin and in the nose – communicate using signals in the 3.18 GHz and 3.45 GHz bands of the radiofrequency (wireless) spectrum. These are the same parts of the spectrum used by WiFi and some 5G technologies.

The authors used a sensitive measuring system to detect radiation in the 1 to 50 GHz frequency range from Staphylococcus aureus biofilms over a 70-day period. They observed the most ‘notable’ radiation in the 3-4 GHz frequency band.

They say that their findings could help demystify how cells communicate.

A biofilm is a colony of microorganisms or microbes (including bacteria) that adhere to each other. They are ubiquitous life forms that are associated with infection and disease.

The findings of this study suggest that, because Staphylococcus aureus bacteria appear to communicate using 3-4 GHz signals, they could well be impacted by the 3-4 GHz signals from man-made technologies.

‘Just imagine what our man-made high-frequency signals, used by cell phones, wireless smart meters, WiFi systems, wireless baby alarms, DECT phones, and many more gadgets/installations/systems, delivered at colossal power levels compared to the natural ones, may do to these intricate communicative mechanisms,’ says Associate Professor Olle Johansson, commenting on the findings.

What is the relevance of these findings to humans?

Science has shown that ‘the human body contains trillions of microorganisms — outnumbering human cells by 10 to 1’ and that ‘this plethora of microbes contribute more genes responsible for human survival than humans contribute’.

In other words, what happens to the body’s microbes, affects the body’s function and health.

‘Perhaps it is high time to start de-smarting our life and our environment, and instead start listening carefully to our bacteria,’ says Johansson.
