What is ELF?Extremely Low Frequency (ELF) has become an issue of concern lately for infrared sauna users. Extremely low frequency radiation falls at the far lower end of the electrical spectrum. These are electrical fields which measure from 0 to 100,000 Hz. One sauna company has been at the forefront in testing and shielding sauna users from ELF. For now, it appears that Clearlight is the first company that has directly addressed this murky area of infrared. This company has been an innovator in infrared technology numerous times during the past 20 years. Again they appear to be the first to directly protect users from extremely low frequency as they state on their website:
Clearlight Saunas have attempted to address the potential issue using two methods. They run all electrical wiring through metal conduit piping, which shields the wiring. They also twist the wires which they state reduces the exposure even further. To our knowledge, this is the only brand to address Electric Fields in this manner.
Are ELF a Health Risk for Sauna Users?The concern about excessive exposure to Electromagnetic Fields, called EMFs, were first raised almost 40 years ago. At that time research showed a connection between exposure to EMF and certain types of serious health conditions including childhood leukemia. Since that time there has been increased awareness regarding the safety of electromagnetic fields. Recently, more concern has been directed specifically at ELF. This is often simply referred to as Electric Fields. Power lines are the most common culprit which radiate an electric field. However, any electrical appliance will radiate some level of Electric Fields. While we cannot completely eliminate all exposure, our goal should be to minimize direct exposure where possible. The sunlighten.com.au website has this to say about this topic:
We know that use of infrared for healing can dramatically improve overall health and that all infrared devices will result in some degree of exposure to electric fields. So the key is to keep the amount at a safe level. What is the safe level for normal activity? In their post Exposure to extremely low frequency magnetic fields induces fos-related antigen-immunoreactivity via activation of dopaminergic d1 receptor, PubMed suggests it to be 1000Mv. The American Cancer Society provides additional examples and information on the risks:
It appears that less is known about ELF than EMF. What is important is that levels above 1000 Mv can potentially be harmful and should be avoided when possible. As previously mentioned, we are pleased to see at least one company aggressively addressing this area of concern. Clearlight's site additionally has this to say about testing levels and the tested level of their units:
We are bombarded by all forms of currents on a daily basis from appliances. It is our opinion at Healing Heat Therapy that while addressing these in regards to infrared use is critical, it is not necessary to reduce all exposure to zero. The important issue is to address them in a significant manner and to substantially reduce the levels of exposures. Once that is accomplished, as consumers we should move ahead with the purchase of a sauna and use it regularly. Being anxious about what little levels remain likely does much more harm to the body through stress than any exposure that remains. We are glad to have witnessed many companies addressing these related issues during the past decade and look forward to seeing more address the issue of ELF as well.
