🎧 The Radiation Concerns of Bluetooth Headphones

Doctor Mike Varshavski addresses the claim that wireless Bluetooth headphones, including AirPods, might be dangerous due to the radiation they emit, potentially causing brain cancer. He explains that all wireless devices emit electromagnetic fields (EMFs), a type of non-ionizing radiation. While high-frequency EMFs can be ionizing and potentially carcinogenic, Bluetooth devices operate at much lower frequencies. Despite concerns, there is a lack of direct evidence linking Bluetooth headphone radiation to health issues. A 2019 study indicates that Bluetooth headphones emit significantly less radiation than cell phones, which have been the focus of most research on this topic. The International Agency for Research on Cancer classified radio frequency radiation from wireless devices as a possible carcinogen based on limited evidence, but no clear causal link has been established. Doctor Mike emphasizes the need for more research but concludes that the current evidence does not support the claim that Bluetooth headphones are dangerous.

🔍 Debunking the Myths Around AirPods and EMF Radiation

The discussion continues with an examination of the specific concerns regarding AirPods and their potential health risks. Despite a Medium article suggesting that AirPods might be dangerous, the World Health Organization's petition did not specifically mention Bluetooth headphones. The article also raises the issue of wireless devices emitting pulses of electromagnetic energy, which some believe could cause cell damage. However, this belief is not supported by substantial evidence in human health. The Federal Communications Commission (FCC) sets safety limits for radiation from wireless devices, and Bluetooth headphones, including AirPods, emit far less radiation than these limits. Doctor Mike clarifies that AirPods, despite being singled out, are well within the safe range of radiation exposure. He suggests that while skepticism is understandable, the current scientific consensus does not support the idea that Bluetooth headphones pose a significant health risk. He also recommends taking breaks from headphone use for reasons unrelated to radiation concerns, such as hearing health and reducing screen time.

Transcripts

- Hey, I'm Doctor Mike Varshavski,

board-certified family medicine doctor.

Welcome to another episode of "Truth or Scare."

On today's episode,

the claim is wireless bluetooth headphones are dangerous

because they emit radiation that might cause brain cancer,

and AirPods are riskier than other types of headphones.

Let's start with saying that all wireless devices,

Wi-Fi routers, baby monitors, cell phones,

video game console, smart watches, headphones, and more,

emit EMFs, also known as electromagnetic fields,

which are technically a type of radiation.

Bluetooth technology uses radiation

in order to connect one wireless device to another,

such as headphones, to an iPhone or laptop.

EMFs actually exist on a frequency spectrum

where frequency essentially means energy,

and we can split these EMFs

into two main categories based on that frequency.

High-frequency EMFs are considered ionizing radiation.

A lot of exposure to that kind of radiation

can change human cell structure enough to cause cancer.

X-ray machines, CT scans,

they all emit low levels of ionizing radiation,

which is why precautions are taken

to use them as little as possible.

UV light is also ionizing,

which is why I always say wear sunscreen

and avoid tanning beds your entire life.

On the other hand,

EMFs from very low- to mid-frequency

are non-ionizing radiation.

Non-ionizing radiation does not have enough energy

to directly damage cell DNA,

which is what happens when cancer develops.

However, with this claim,

the theory is that low- and moderate-frequency EMFs

might not be directly causing cellular DNA damage,

but perhaps over time,

because we're not just using these headphones

for a second or two,

that damage ultimately can arise.

But what does the evidence tell us about all of this?

To be honest, there haven't been direct studies

on looking at the health impacts of radiation

from Bluetooth headphones.

Most of the research exploring the potential link

between non-ionizing EMFs and cancer

has focused on cell phones.

And although cell phones and Bluetooth headphones

both emit the same kind of non-ionizing radiation,

Bluetooth headphones emit a lot less of it,

10 to 400 times less, according to one 2019 study.

And at this point,

there are some experts

that believe cell phones are a potential risk for cancer,

and they've been quite vocal about their concerns

for a while.

Back in 2011,

the International Agency for Research on Cancer,

which is an agency within the WHO

that evaluates cancer risks

classified radio frequency radiation from wireless devices

as a possible carcinogen.

The main evidence at the time

was a large observational study

that actually didn't find an overall increased risk

of brain tumors from cell phone usage.

But the study did find statistical association,

so a correlation, not causation,

between malignant brain tumors called gliomas

and those who had the highest levels of cell phone exposure.

But researchers warned that the association was not strong

and that the data was hard to make sense of

because there's so many confounders,

meaning other factors besides cell phone usage

that could have explained why people ended up

with brain cancer.

Then, in 2015,

more than 200 scientists

petitioned the World Health Organization and United Nations

for stricter rules around non-ionizing EMFs

and referenced the 2011 decision

to classify it as a potential carcinogen.

The scientists argued that radiation emissions

from wireless devices

might be harmful at levels deemed safe

under the existing guidelines.

The petition came on the heels of a study

that showed the heaviest users of cell phones

and cordless phones

were somewhat more likely to be diagnosed with meningiomas,

which is a type of slow-growing brain tumor.

But the association was, again,

too weak for researchers to conclude that cell phone use

generally caused meningiomas.

Some more recent studies have been done,

and they do suggest a link

between cell phone usage and cancer

or biological changes that might enable tumor formation,

but all of them had flaws or substantial limitations.

So the results have been framed

as a reason to do more research

and not as clear evidence that cell phone radiation

is a risk factor for brain cancer.

For example, one 2018 study

found that high levels of radio frequency radiation

caused cancerous heart tumors in male rats and mice.

The study certainly made headlines,

but researchers said the results

could not be generalized to humans.

First of all, the way that the rodents

were exposed to radiation in the study

was not how we use cell phones.

And at the end of the day, rats aren't people.

(suspenseful music)

It's a good first step

and maybe it'll guide further research,

but it doesn't give us a clear answer as of yet.

Moving on, in 2020,

the FDA published a review of 125 studies,

exploring that potential link

between radio frequency radiation and cancer.

They looked at a mix of animal research

and observational studies on humans.

They found no consistent pattern to support a link.

There are good reasons

to keep investigating these potential health risks

of cell phones.

They've evolved a lot since they became popular,

and so has the way we use them.

Also, we're no longer talking primarily about adults.

Today, most kids have their own cell phones,

and kids don't necessarily respond the same way as adults do

when they're exposed to potential environmental health risks

like toxic chemicals or viruses,

so maybe the same will go for EMF.

It's important for scientific knowledge

to keep up with this modern technology,

so the call for more research

isn't really a reason to panic.

It's the responsible path forward.

But let's go back to Bluetooth headphones,

which became a bigger part

of this whole conversation in 2019

when a Medium article that argued AirPods might be dangerous

and referenced the 2015 WHO petition.

The fact that the WHO petition

had not specifically mentioned Bluetooth headphones

didn't seem to even matter.

The article came out the same year as AirPods did,

so they were already in the spotlight.

The Medium article also brought up the idea

that the amount of radiation emitted by wireless devices

isn't the only factor in their potential health effects.

See, wireless tech emits short births

of electromagnetic energy called pulses,

which the article said might be able to cause cell damage

at a lower intensity level than non-pulsing radiation could.

One expert said this factor is ignored

by government health agencies,

and therefore isn't captured by safety guidelines.

There's some rat research on electromagnetic pulses,

but as far as human health goes,

this is not exactly an evidence-based belief.

But is someone out there

actually making sure your headphones

aren't blasting you with dangerous radiation?

Yes.

The Federal Communications Commission, or FCC,

sets maximum exposure limits for radiation

emitted from cell phones, cell phone towers,

and all wireless devices sold in the US.

These radiation limits

are based on how much radio frequency energy

can be safely absorbed into the body,

and they're lower than what's been deemed safe in research.

That means there's actually a built-in margin of safety.

The rate at which you absorb radiation from a device

is called its specific absorption rate.

This rate is based on emissions measured from the device

when it's operating at its highest possible power levels.

Specific absorption rates for Bluetooth headphones

don't come anywhere near the FCC radiation limits.

This is true no matter which brand or kind you have.

AirPods have unfortunately been singled out

as more dangerous than over-the-head Bluetooth headphones

because they supposedly emit five times as much radiation

and maybe that they sit directly inside your ear canal

so they're closer to the brain.

But the five times number, it's a myth,

and the radiation from AirPods

is well within the safer use range.

Recent models amid a maximum of 8%

of the FCC radiation limit,

and that's the safe limit, so 8% of the safe limit.

That being said, skepticism around wireless devices

is widespread enough that the FCC published suggestions

for how to decrease radiation exposure from them

while also clarifying at the same time

that the agency does not endorse any need

to take reduction measures.

But where does all of this leave us?

You are exposed to non-ionizing radiation

from so many devices in your life.

It's all around you.

Exposure from Bluetooth is just a small piece of that pie.

Bluetooth worries were, and are,

mainly based on the possibility of cell phones causing harm.

And we currently don't have strong evidence

that cell phones are harmful,

at least in that sense.

And the leap to Bluetooth is probably a huge one,

given that they release so much fewer EMF than cell phones,

and that's because cell phones

need to communicate with cell towers miles away.

A Bluetooth device only needs enough radio frequency

to connect with a phone or laptop that's in the other room.

Less distance equals less energy and probably less damage.

One thing about headphones, though,

that understandably makes people uneasy

is that it's common to wear them for hours on end

and on a daily basis.

So this heavy usage is typical behavior,

and if there's any chance they're dangerous to use

and you've been using them a lot,

I can understand, those implications can be scary.

But remember that right now,

studies about cell phones and cancer

that have involved humans

have not been able to support a causal link.

While we can't say with 100% certainty

that there isn't one,

but it's a good thing

when researchers keep looking for something bad

and can't even find it.

If you're nervous about radio frequency radiation exposure,

you could always take AirPod breaks

or alternate between wireless and wired headphones.

In fact, it might be a good idea

to spend more time headphone-free and cell-phone-free

for reasons unrelated to brain cancer fears,

like the potential impact on your hearing,

and accident risk,

and cell phone addiction 'cause that's a real thing.

So on my Truth or Scare scale where zero is complete BS

and 10 is absolute truth,

this claim gets a 3.5.

Some of these were absolutely awful.
