There have been health concerns about the possible danger of wireless devices, including Bluetooth earbuds, since 2015 after 247 scientists from 42 countries petitioned the World Health Organisation (WHO).
The scientists raised safety concerns about the effects of exposure to the electromagnetic fields (EMFs) that’s emitted from wireless devices.
A recent viral video on X has sparked a widespread panic over the use of wireless devices. In the video, a woman claimed her friend developed brain cancer due to constant use of earbuds.
The young lady alleged that earbud devices send signals directly to the brain, potentially causing cancer.
Let’s look at the facts to understand if these concerns are valid.
What is electromagnetic radiation?
Every day, as we connect our Bluetooth and wireless headphones, interact on our computers and cell phones, or even use our microwave ovens, we’re surrounded by a type of low-level electromagnetic field (EMF) known as radio frequency radiation (RFR).
Back in 2011, the International Agency for Research on Cancer raised some eyebrows when it flagged RFR as possibly carcinogenic to humans. This concern originated from studies showing a connection between extensive cell phone use and an increased occurrence of glioma, a type of brain tumour.
Adding to the concern, in 2018, research by the National Toxicology Program revealed that high exposure to RFR – like the kind from older 2G and 3G cell phones – might even cause cancer in rats.
Now, the big questions we face are about what these findings mean for us. How do they translate to human health? And just what levels of RFR exposure could be considered dangerous?
Scientist’s view about Bluetooth and Cancer
Joel M. Moskowitz, PhD, who leads the Center for Family and Community Health at the University of California, Berkeley, points out that while there’s a lot of study on the general health risks of EMFs (electromagnetic fields), the long-term safety of radiation from Bluetooth or wireless headphones hasn’t been studied much.
This means scientists are still trying to figure out if these popular devices are safe to use for years.
The radiation from Bluetooth devices is called “non-ionizing.” This type of radiation doesn’t damage DNA like some other types can.
Many studies have looked at whether cell phones, which use similar but stronger signals than Bluetooth, can cause brain cancer.
So far, most scientists and health organisations like the WHO agree that there’s no clear proof that using cell phones or wireless devices can cause brain cancer.
Understanding the safety of wireless Headphones
Bluetooth and wireless headphones give off less radiation than cell phones, but their close position to our heads worries some health experts.
Joel M. Moskowitz says that even though these devices are right next to our head or body, the amount of radiation the head gets is only about half or a third of what you would get from a cell phone.
Moskowitz points out that the Federal Communications Commission (FCC) has set safety limits on how much radiation wireless devices can emit.
This limit is 1.6 watts per kilogram, a rule made in the mid-1990s to protect us from the immediate risks of heating from these devices.
For example, Apple AirPods have a radiation level of about 0.466 watts per kilogram, which is well below the FCC’s limit.
However, even though products like AirPods meet these safety standards, many scientists are still concerned.
They question whether the current rules are good enough to protect us from the possible dangers of using these devices for a long time.
Some experts think that even low levels of radiation from regular and long-term use could build up and potentially harm our health over time.
Safety use of earbuds
1. Use wired headphones: These don’t use Bluetooth, so there’s no radio wave exposure.
2. Limit how long you use them: Take breaks if you wear Bluetooth earbuds for a long time.
3. Keep the volume down: Protect your hearing by not playing music too loudly.
4. Try other options: Use the speakerphone or other hands-free tools when you can.
