if the waves are bad for your health is a combination of the frequency of the waves, the effect, and how long you are exposed to it...
Bluetooth uses the frequency area around 2.6GHz (same area used by e.g. wireless networks and microwave ovens)... but the effect is quite small...
the GSM networks are on lower frequencies (which is less harmful to humans than higher frequencies), 900, 1800 and 1900MHz, but then on the other hand, the effect is often much higher...

BTemits at 2.4GHz with the power of 0.001W compared to a regular cell phone emitting between 1 and 2 Watts. So you can see it's at least a thousand times less -- nothing to worry about

Any radio transmitter uses radiation to transmitt data of any kind.
I believe cell phones can penitrate 2cms 900mhz or more into flesh.
Maggers worry is from the fact that both Microwave ovens and Bluetooth operate on the same 2.4Ghz frequency. Dont worry, the wattage for all Bluetooth profiles (which gives them their ranges from 10m all the way up to 200meters) will not "cook" your brain. remember even though 2.4Ghz is needed to oscillate water molecules its the power rate that the oscilation takes place in order to see an incremental value of temperature increase. I do believe that Bluetooth will not increase temperature (significantly or otherwise).
Since you use your phone to your ear frequently the warmth on your ear is caused by insulating the heat radiating from your head--you got an artery going through your ear lobe. Remember when your mom made you wear your tuke to go outside to play in the winter time? Thats because your head can dissapate heat quickly, hehe!
hope that this makes you feel better
