Not all Bluetooth earbuds are safe, but there are some precautions you can take to ensure they are. Be sure to clean them periodically to avoid eardrum damage. Invest in premium earbuds for the best sound quality. People are starting to question whether Bluetooth wireless headphones are safe to use.
If you’re not sure if they are safe, take precautions and don’t use them. Even if there is no evidence to show that wireless headphones can cause ear damage, the fact that you cannot see the sound waves makes it difficult to be specific. In this article, Hooke Audio will show you, Are Bluetooth Headphones Safe?
What Exactly Is Electromagnetic Radiation?
The invisible energy or radiation known as electromagnetic fields, also called an electromagnetic fields, is produced by electricity.
Bluetooth and wireless headphones emit radiofrequency radiation (RFR), a nonionizing, or low-level, EMF.
The International Agency for Research on Cancer (IARC) classified this radiation as potentially carcinogenic to people in 2011. This classification was based upon an increased risk for glioma (a type of brain cancer) due to cell phone usage.
In 2018, the National Toxicology Program’s (NTP) research found that high levels of RFR, such as those used in 2G or 3G cell phones, could cause cancer in rats.
We now have to ask ourselves how these findings relate to humans and which specific RFR levels may be a danger to our health.
- Fields of ionizing radiation are more potent than other types and have shorter wavelengths.
- This type of radiation can destroyTrusted Source electrons in atoms.
- This causes chemical bonds to be broken.
- High doses of ionizing radiation in the body can cause unstable atoms, known as free radicals, to generate oxidative damagesTrusted Source.
- Gamma rays and X-rays are two other sources of ionizing radio that are more commonly used.
- Visible light is located in the middle of the spectrum. It marks the boundary between nonionizing and ionizing radiation.
- Nonionizing EMFs are shorter in wavelength and have a lower frequency. They can’t break chemical bonds.
- Many Trusted Source forms, both natural and artificial, contain nonionizing fields.
- These are some sources of nonionizing EMFs:
- Radiofrequency radiation is used in many communication devices microwaves
- UV radiation is used in tanning beds
- Infrared radiation is also used in heat lamps
Are Bluetooth Headphones Safe?
Bluetooth is a nonionizing EMR and, therefore, generally safe for humans. It will not cause any health problems.
Bluetooth is safe for humans because it has a low specific absorption rate (SAR).
The Federal Communication Commission (FCC), in the United States, requires that phones have a minimum SAR level of 1.6 Watts per kilogram (W/kg). The SAR limit for handheld and mobile devices in the European Union is 2 W/kg.
These levels are safe for humans. SAR levels for Bluetooth devices can be lower.
Apple Airpods, for instance, have a SAR value of only 0.072 W/kg (for the head) and 0.603 W/kg (for the body). Airport Class 1 transmission power is a significant advantage over other Bluetooth devices. Bluetooth headphones in Class 2 and 3 have lower SAR values than the majority.
These SAR levels show that Bluetooth devices are safe for human health. They are not even close to the minimal levels that could affect human health.
Bluetooth devices emit radiation, so people are still cautious about this. Radiation is often linked to health problems and concerns. People still have concerns about the safety of Bluetooth devices.
How Do They Affect Our Health?
Because it can cause chemical bonds to be broken and alter the molecular structures of many substances, including human tissue, ionizing radiation can prove to be dangerous.
A person is more susceptible to radiation exposure if they are exposed for a longer time. For example, a person could be exposed to X-rays over a more extended period without protection.
High doses of radio ionizing radiation can cause damage immediately. Source:
- Hair loss
- Skin damage
- Organ and tissue damage
- Damage to a developing fetus
- Bone marrow damage
Even if there are no symptoms immediately, this radiation can cause long-term problems for a person’s health.
Some problems that may develop over a more extended period include:
- Oxidative damage
- Fertility complications
- Effects on developing fetus
The World Health Organization (WHO) states that medical applications such as radiation therapy and X-rays account for 98% of all radiation doses from all sources, 20% of total population exposure.
Physicians and other healthcare professionals can reduceTrusted Source radiation exposure by using lead shields that protect the body from radiation.
The average levels of nonionizing radiation that are acceptable for human health should not exceed the Trusted Source. Ordinarily, nonionizing radiation passes through the body without causing any harm.
Concerns have been raised about a possible interference with pacemakers and other devices.
According to the American Heart Association, pacemakers are not usually affected by radiation from household devices like microwaves and computers.
Yet, the AHA does recommend keeping antennae and motors roughly 6 inches away from a pacemaker or implantable cardioverter-defibrillator.
Cell phones have been implicated in cancer-causing factors. The Indian Journal of Occupational and Environmental MedicineTrusted Source authors noted that evidence of a link between cell phone radiation and cancer is weak and insubstantial.
International Agency for Research on CancerTrusted Source has declared radiofrequency radiation a possible human cancer gene. Scientific studies are being done to find out if cell phone use can cause adverse health effects.
According to the Centers for Disease Control and Prevention, Trusted Source states that more research is required before determining if cell phone use causes adverse health effects.
Nonionizing radiation can produce heat, such as in a microwave. Although this heat isn’t usually dangerous, it can cause damage to human tissue in certain situations.
People who work in scientific or industrial settings and are exposed to high doses of trusted sources of nonionizing radio radiation may be at increased risk for tissue damage.
Some organs are more vulnerable than others. The eyes and the testes are, for instance, more vulnerable because they have a lower blood supply and are less capable of regulating temperature.
The riskTrusted Source for damage from nonionizing radiation is shallow. It only occurs after long-term exposure to high levels of radiation.
Bluetooth Headphones: Common Safety Concerns
Some websites claim that Bluetooth can cause severe health problems and be harmful.
These claims might not be valid. We’ll address some of the most common myths and concerns about Bluetooth radiation and its effects on the human body.
Can Bluetooth Cause Cancer?
A 2015 study found that mobile phone users are at a somewhat higher risk of developing meningioma (a type of brain tumor). Similar concerns were raised about the safety of Bluetooth and other nonionizing EMR emitting devices like Bluetooth.
However, this study did not indicate an increased risk of brain tumors. The study didn’t prove that mobile phones could directly cause cancer.
Multiple studies have attempted to replicate the results of this study, but no evidence has been found to support it. There is no evidence that mobile phone use causes or increases cancer risk. At best, the evidence linking them is weak.
Nonionizing EMR devices, in general, don’t seem to have an associated effect on cancer risk. A study found that children exposed to nonionizing EMR have the same chance of developing childhood cancer as children who are not.
Last but not least, Bluetooth devices have significantly lower SAR than cell phones. The purported cancer risk from mobile phones cannot be applied to Bluetooth devices. It makes sense that they might even be more harmful than mobile phones.
Are Wireless Headphones Able to Make Me Sterile?
Wireless headphones have been linked to infertility, and cell phone use has sparked concerns about their safety.
In 2009, a study published in Fertility and Sterility stated that mobile phones placed near the testicles, such as in pockets or attached to the belt, can cause damage to the testes and affect sperm quality.
Studies later found that extended use of mobile phones can cause significant changes in sperm parameters, such as sperm count, motility, and morphology. The increased oxidative stress caused by EMR from mobile phones is believed to be the cause.
Furthermore, factors like proximity to the testes and prolonged use of mobile phones can influence oxidative stress in the sperm. These factors don’t apply to Bluetooth devices which are usually used far away from the lower half.
However, it is still not clear if Bluetooth devices can cause male sterility. Therefore, it is not possible to conclude that Bluetooth devices can cause you to become sterile.
Will Being Surrounded by Bluetooth “cook My Brain”?
You might be curious whether Bluetooth headphones can generate enough heat to cook your brain.
Bluetooth headphones have a low power output, so even if radio waves reach your brain from them, they won’t cause any lasting damage. Even after hours of usage, Bluetooth headphones don’t produce enough heat for your brain to cause any permanent damage.
Bluetooth headphones are not as powerful as microwaves. They only require 850- 1800W to work. Bluetooth headphones emit 100 mW, which is approximately 8,500 to 18,000 times less power than microwaves.
This power discrepancy allows microwaves to cook food and protects your head when you use Bluetooth headphones.
Bluetooth headphones can be worn in the ear but don’t cause any significant changes in cochlear nerve activity. The risk that Bluetooth headphones could cause cancer or other brain diseases is not supported by evidence despite their proximity to the brain.
Bluetooth headphones won’t cause your brain to burn, so we are confident that they will not.
As you can see, Bluetooth devices are pretty safe and pose no danger to the health of anyone. We hope that our article has helped clear up any misconceptions people may have about the safety of Bluetooth Headphones.
