Are Bluetooth Headphones Dangerous?

are Bluetooth headphones dangerous

The Bluetooth devices including headphones release low quantities of nonionizing radiation. Low levels of these radiations do not cause any damage to people. According to the FDA, nonionizing radiation is generally regarded as safe for humans. Here, we will see are Bluetooth headphones dangerous or not?

We will discuss why people are concerned about Bluetooth headphones. The evidence about the safety of utilizing these gadgets will also be examined here.

What is EMR or Electromagnetic radiation?

Electromagnetic fields are invisible zones of energy or radiation created by electricity.

According to the National Institute of Environmental Health Sciences, the invisible area of energy is termed EMR or electromagnetic radiation. These EMR radiations can be emitted by both natural and man-made sources.

The nonionizing waves emitted by the gadgets are safe for humans to utilize.

When a body generates energy, the energy travels at various frequencies. The greater frequency of radiation is linked with higher energy levels.

Bluetooth and wireless headphones, as well as mobile phones, and even microwave ovens used in our homes, generate a kind of non-ionizing EMR known as radiofrequency radiation (RFR).

Some studies claim these radiations may pose a threat to humans, while some do not. Now, the question is which particular type is responsible for health issues in humans.

EMR is classified into two types:

Ionizing Electromagnetic radiation

Ionizing EMR waves can harm human cells due to their high frequency. The word ionizing refers to the EMR’s ability to take electrons from atoms. Due to its higher frequency, ionizing EMR is more dangerous than non-EMR.

Below are the sources of ionizing EMR:

  • Heat and light energy from Sun
  • Radiations from building materials
  • X-ray machines
  • Radioactive waste and elements

Nonionizing Electromagnetic radiation

These EMR waves have a low frequency and, in most cases, have no detrimental impact on people.

Nonionizing EMR sources include:

  • Bluetooth devices
  • Mobile phones
  • Laptops
  • Infrared radiations in lamps
  • Power lines
  • Microwaves radiations used in home appliances
  • MRI machines
  • UV radiations from tanning beds
  • WIFI networks
  • Energy smart meters

Are Bluetooth headphones dangerous or safe?

There are not enough studies done on the usage of Bluetooth headphones. The majority of research is focused on high-level nonionizing radiation exposure.

The frequency and duration of exposure may affect the health of a person. Using Bluetooth headphones for extended durations can be dangerous, but only limited animal studies have shown this.

Nonionizing radiation is only hazardous when in direct contact with a person. This scenario is uncommon and only a worry for people who work on nonionizing radiation-producing sensors and technologies for longer periods.

The result of studies regarding the health consequences of nonionizing EMR varies. Some studies believe that nonionizing EMR is dangerous, while some believe they are not. Scientific reports can be controversial and vary.

According to various studies, scientific publications might be contentious and conflicting. However, there is mounting evidence that nonionizing EMR may pose certain health hazards.

It is observed, exposure to high amounts of non-ionizing EMR can virtually triple the likelihood of miscarriage. Women who have high levels of nonionizing EMR exposure during their pregnancies are more likely to have children with ADHD.

The potential risk of cell phone use

Scientists investigated the dangers of cell phones, radiation, and their use. According to one study, cell phones may lead to brain tumors. Tumors were visible in male rats that had been exposed to nonionizing EMR during the research.

The rats were subjected to radiation in a way that created conditions that differed from those encountered by humans while using mobile phones.

According to the researchers, these findings in animals may not apply in the same way to humans. During these studies, the intensity and duration of radiation exposure were greater than what individuals experienced from cell phones.

Certain forms of nonionizing EMR have been identified as potentially hazardous to humans by the International Agency for Research on Cancer. Some kind of brain cancers like Glioma has been linked to cell phone use.

Despite increased cell phone use, brain cancer rates in the USA have remained consistent. This steadiness demonstrates that mobile phone use does not raise the chance of developing brain cancer.

Different devices or gadgets generate different levels of non-ionizing EMR. According to one research, Bluetooth headphones create less EMR than a conventional mobile phone.

Even though mobile phone use raises the risk of some health disorders, using Bluetooth headphones may still be safe.

What is causing the concern?

More than 200 scientists signed an appeal to the WHO and the UN (2015). Several studies, according to the experts: have indicated that EMR may be detrimental to people even at levels far lower than the current limits allow.

The scientists identify the following as potential consequences of non-ionizing EMR overexposure:

  • Risk of certain types of cancers
  • Mental problems
  • Increase in free radical production
  • Genetic harm
  • Various neurological disorders

The scientists proposed many new safety precautions in their appeal, including:

  • Additional safeguards against EMR for Children and pregnant women
  • Reinforcing EMR rules
  • Introducing EMR free zones
  • Educating the people about the potential health risks of EMR

The scientists who penned this plea made no mention of Bluetooth headphones. However, the appeal was acknowledged by the authors of a 2019 study concerning the safety of Bluetooth headphones.

That is why some individuals are concerned that Bluetooth headphones are harmful to use. Even though non-ionizing EMR is far safer than ionizing EMR, some experts are concerned that it may be more hazardous than we realize.

Cancer, neurological problems, and DNA damage are among the concerns. More research, however, is needed to confirm these concerns.

Which precautions to take

Until we reach a final decision, all we can do is take extra care to prevent the potential health dangers of using Bluetooth headphones.

According to Healthline, “If you want to make long phone calls, use speaker or wired headphones.

The rule also applies to the people who listen to music for several hours every day. This is especially crucial for children who are more vulnerable to radiation.

One of the basic recommendations is to keep your cell phone 10 inches away from your face, as poor signals strength produces more radiation.

We may all take steps to reduce the amount of radiation we are exposed to regularly. It is the best strategy to avoid radiation as much as possible.


There is currently no evidence to support the idea that wearing headphones is hazardous to one’s health. Scientists are unsure if prolonged exposure to high amounts of non-ionizing EMR is hazardous.

It is critical to realize that cell phones emit more EMR than headphones.

The researchers are unsure if the Bluetooth headphones are dangerous or safe to use.

Some folks may choose to remain on the safe side while using their Bluetooth headphones. They can reduce their reliance on Bluetooth headphones and other wireless gadgets to avoid potential health risks.
