Don't use bluetooth handset too much

The use of headsets has become pervasive in the business world. However, some potentially detrimental health consequences can emerge from using headsets, especially if they are not used and maintained in the optimal manner. This is not meant as a discouragement of their use. Personal and employee health are both very important in the workplace. As long as a few simple precautions are taken, headsets can be used and their benefits taken advantage of without exposing anyone to the possible harmful effects of their use.


Hearing Loss
Anytime a speaker projects sound directly into your ear, there is the potential for hearing damage. The UCLA Ergonomics Division states that the volume of a user's headset is the largest factor in whether or not there is a risk of hearing loss. They suggest that the volume on the headset be kept low enough that someone sitting next to the user cannot overhear the conversation. It is also recommended that users of headsets take breaks of a few minutes every half hour to prevent fatigue of the auditory system.

Germs
The telephone, or the headset that accompanies it, can be one of the most prolific breeding grounds for germs in your office. University of Arizona Professor of Microbiology Charles Gerba did research on the various places where germs congregate in the work environment and found phones and headsets to be far more germ infested than more obvious culprits such as toilet seats. Headsets should be cleaned regularly with a disinfecting product to help reduce the buildup of disease causing germs.

Vocal Strain
Improper use of a headset can cause vocal strain, especially if the person using the headset is talking throughout most of their work day. If the headset has an adjustable microphone, make sure it is positioned so that it picks up a clear signal from your voice without requiring strain to speak. Speaking in a quiet, relaxed manner throughout the day helps to prevent vocal injuries. If the headset is only an earpiece with an attached mic, ensure that the input level is turned up high enough that you don't need to strain your voice.

Radiation
Questions have been raised by many groups regarding the radiation that you could be exposed to when using a Bluetooth headset. In actuality, the amount of radiation emitted from these devices is well under the threshold of what is considered harmful. While studies have still not conclusively shown that even cell phone radiation is harmful, a Bluetooth headset actually reduces the radiation that you are exposed to compared to holding your phone up to your ear. Any radiation in excess of a 1.6 watt per kilogram absorption rate is considered to be unhealthy. Standard Bluetooth headsets only emit enough radiation to be absorbed at a rate of around .001 watts per kilogram.
