Is Bluetooth or WiFi Radiation Harmful?
Worried that your mobile phone might be a bearer of bad news? Concerned about the dangers that could be lurking in your Bluetooth earphones?
The advent of technology has drastically affected all aspects of our lives. While some believe that this change is for the better, others aren’t so convinced. Recently, experts from different fields have become increasingly interested in the topic of digital devices and the potential risks associated with them.
One of the burning questions nowadays refers to the possible side effects of electromagnetic radiation through radio frequent energy.
Some professionals believe that wireless and Bluetooth technologies pose a significant risk to one’s health, going so far to assume that digital devices such as cellphones, tablets, routers, and headsets can cause cancer and other underlying issues in humans.
So, are these concerns justified? Is Bluetooth or Wifi radiation harmful?
To answer those questions, first, we need to familiarize ourselves more with the topics surrounding RF signals and radiation in general. Afterward, we’re going to take a quick look at what the experts have to say about this hot-spot issue.
What is Radiation?
If we were to take a textbook approach we could say that “radiation is the emission or transmission of energy in the form of waves or particles through space or a material medium.”
Depending on the energy of the radiated particles, radiation can be categorized as ionizing nonionizing. The ionizing radiation is so powerful that it can physically transform an affected atom or molecule. This kind of radiation is deemed extremely dangerous to humans, as well as all other living organisms, as it can alter our DNA, a process that often leads to cancer.
However, non-ionizing radiation is considered low-energy radiation. That means that it’s unable to physically alter atoms or molecules. While frequent exposure to this type of radiation can have possible side-effects, it is not powerful enough to penetrate deep into the tissue and cause severe health conditions.
The type of radiation that can cause biological damage is called ionizing radiation. There are two types of harmful radiation associated with ionizing radiation:
- Electromagnetic radiation
- Particle radiation
Although electromagnetic and particle radiation are somewhat different than ionizing radiation itself, they’re still extremely dangerous to all living things. Ultraviolet radiation, X-rays and thermonuclear explosions are just a few examples of these types of energy emissions that can cause damage to biological molecules.
Visible light, radio waves and thermal radiation are all types of non-ionizing radiation. They can all be categorized as:
- Acoustic radiation
- Gravitational radiation
These electromagnetic waves are not strong enough to cause biological harm. Bluetooth or Wifi radiation is also non-ionizing radiation, meaning it doesn’t pose a threat to humans in a traditional sense.
How Does Bluetooth/Wifi Radiation Work?
Although not entirely the same, the one thing Bluetooth and Wifi have in common is the fact that they both use radio waves to emit signals and transfer data over short distances.
Radio waves, also known as radiofrequency and RF energy, is a soft form of electromagnetic energy in which electric and magnetic waves advance together through electromagnetic fields.
Many studies have been conducted in regards to the dangers of this type of electromagnetic radiation, but the results so far are inconclusive. Researchers have failed to provide sufficient evidence to support the claim that the usage of Bluetooth and Wifi supported devices can cause health problems.
However, research suggests that over-exposure to RF EMR could possibly be grounds for concern. Of course, certain experts believe that these studies are ambiguous because the amount of exposure needed to cause significant damage can not be achieved in normal circumstances through everyday use of cellphones or Bluetooth devices. It is their opinion that this amount of critical exposure is only possible in specialized conditions and highly controlled environments.
Is Bluetooth or Wifi Radiation Harmful?
No, it is not. At least not in the traditional sense.
Nothing suggests that regular usage of Bluetooth or Wifi powered devices can cause cancer or any other type of biological harm.
Nevertheless, if you are concerned and wish to protect yourself from the potential dangers of Bluetooth/Wifi radiation, it’s possible to take some precautionary steps to limit your exposure to RF signals.
Some experts suggest turning your mobile phone off or putting it on airplane mode when going to sleep. It’s also a good idea not to sleep next to your smartphone, tablet and other Bluetooth supported devices. Another way to limit exposure is to position your routers in rooms where you spend the least amount of time in. It’s also a good idea to use wired earphones or speaker-mode when responding to calls on your mobile phone.
Finally, try to keep your devices at a safe distance from your head and body when in use.
