People worry that wearing a radio-transmitting gadget on their head is going to cause some health issues. Let’s face it: Despite what comic books may have us believe, radiation rarely gives you superpowers. It’s generally something we want to stay away from.
But is radiation from Bluetooth headsets something to be worried about? The short answer is no – if you ask the scientists who study it. To understand why, let’s talk briefly about cell phone radiation studies first.
Cell phone radiation has been extensively studied. Scientists wanted to evaluate the potential health risks, especially when it came to cancer. What did they find?
American Cancer Society offers a thorough overview of all the studies to date. The basic consensus is that current research does not point to any obvious link to health issues from cell phone use. To quote a few expert agencies mentioned in the article:
“The majority of studies published have failed to show an association between exposure to radiofrequency from a cell phone and health problems”
– Food and Drug Administration
“At this time we do not have the science to link health problems to cell phone use. Scientific studies are underway to determine whether cell phone use may cause health effects.”
– Center for Disease Control and Prevention
“There is no scientific evidence that proves that wireless phone usage can lead to cancer or a variety of other problems, including headaches, dizziness or memory loss.”
– Federal Communications Commission
Nevertheless, more research is ongoing and people are encouraged to exercise caution and limit their exposure, especially when giving cell phones to children.
What does all of this mean for Bluetooth headsets? Well…
Unlike cell phones, which have to transmit a signal to an antenna that might be many kilometers away, Bluetooth headsets only need to reach the phone in your pocket. Most Bluetooth headsets have a range of only 10 meters (30 feet). This also means that they emit far less radiation than cell phones themselves. How much less? One thousand times less.
That’s why most authorities explicitly advise using hands-free devices including Bluetooth headsets if you’re worried about radiation exposure from cell phones. For instance:
“To reduce radio frequency radiation near your body: Get a hands-free headset that connects directly to your phone.”
“Headsets can substantially reduce exposure since the phone is held away from the head in the user’s hand or in approved body-worn accessories.”
“Use the speaker mode on the phone or a hands-free device such as a corded or cordless earpiece. This moves the antenna away from your head, which decreases the amount of RF waves that reach the head.”
In a nutshell, if you’re going to be talking on a cell phone no matter what, using a Bluetooth headset will help you reduce exposure to radiation.
