I was cycling with the buddies and noticed many of them wearing the bluetooth headsets to listen to music and answer those important calls. Tsk Tsk guys. Very dangerous. But you an't deny the rise of the bluetooth in recent months especially when the iphone got rid of the earphone jack. So what do most people do? Go buy a bluetooth earphone to connect on. Not only does it do away with the wires but also makes workouts fun. Hence the guys cycling and listen to music. I would rather have a bluetooth transmitter to enable my favorite set of earphones to be wireless. Not many on the market at the moment with the Griffin Itrip Clip the only one that seems to be reliable. I guess if you want to avoid holding their phones up to your ears then you have to rely on Bluetooth ear buds for now.
Anyway, I bought this up to my best friend and he hates bluetooth, wireless and wifi. He believes it gives him a headache and is invariably linked to cancer. Well, good topic for us to look into. Is Bluetooth dangerous? To your health I mean
Bluetooth, named after Danish King Harald Bluetooth, who united all of Scandinavia in the 900s, is a protocol that uses electromagnetic waves for short-range communication between devices. Though it was developed in the 1990s, it has recently become ubiquitous in many of the "smart devices" used in the Internet of Things.
However, from a physics perspective, Bluetooth is basically Wi-Fi light, Moulder said. Bluetooth waves have frequencies that are roughly similar to those of Wi-Fi (close to the range of frequencies of microwaves) but Bluetooth is far less powerful, Moulder said. In general, the ranges of wireless communication protocols such as Bluetooth or Wi-Fi predicts how much power they emit, Moulder said.
It turns out that there is no evidence that Bluetooth does any harm. In addition, there are no plausible physics mechanisms by which Bluetooth could cause damage to a person's cells, said John Moulder, a professor emeritus and radiation biologist at Medical College of Wisconsin in Milwaukee. "The power is just too low to damage anything biological by any mechanism we know of," Moulder told Live Science. "If it's going to damage you, it has to be via a mechanism that no one has ever conceived of.
"It's sort of like Wi-Fi, except a tenth to a hundredth of the power," Moulder said. Worries about whether the electromagnetic radiation associated with modern gadgets may cause illness are not new. The internet is rife with concerns about the effects of cellphone radiation and Wi-Fi, and even the World Health Organization acknowledges that some people may have a condition called EMF hypersensitivity. Those with this condition experience physical symptoms such as headaches and nausea that they believe are caused by electromagnetic fields. Some have even gone so far as to move to remote areas of West Virginia that are free from radio waves.
The safety concerns are even lower for Bluetooth than for Wi-FI, Moulder said. In traditional Bluetooth devices pairings — for instance, a smartwatch worn on the wrist that is occasionally communicating with a computer — the power of the electromagnetic radiation is so low and the communication so sporadic that it's extremely unlikely that it could cause any harm, Moulder said.
There are dangers, of course, associated with cellphones that don't involve any radiation at all. For instance, studies have shown that talking on hands-free Bluetooth earphones is less safe for drivers than not talking on a phone at all, likely because the driver gets distracted by conversation with a distant partner, Moulder said. Also, people who wear headphones and blast their music — whether those headphones use Bluetooth or not — can damage their hearing, Moulder said. And frequent texting can lead to thumb problems and carpal tunnel syndrome, he said.
So there you have it, no one knows for sure if it 100% safe but looks like it. And you are probably going to face other problems than bluetooth radiation. If you need to be sure then use the solution below. I think it's kind of overboard and you probably have bigger problems like making sure your thumbs don't suffer from the same syndrome as your legs after being in the plane for an extended time. Keep flexing and stretching those thumbs.
