EMF in Infrared Saunas


First we have to define EMF. EMF stands for Electromagnetic Field which in simple terms are magnetic field that is generated when electrical current flows. Exposure to electromagnetic fields is not a new phenomenon. However, during the 20th century, environmental exposure to man-made electromagnetic fields has been steadily increasing as growing electricity demand, ever-advancing technologies and changes in social behavior have created more and more artificial sources. Everyone is exposed to a complex mix of weak electric and magnetic fields, both at home and at work, from the generation and transmission of electricity, domestic appliances and industrial equipment, to telecommunications and broadcasting.

Is EMF Dangerous

There is a lot of talk about EMF and it's dangers, but some people will not provide any evidence for their views or cite studies that cannot be found or were done on a different subjects. Most of the recent studies on EMF were done to show the effects on children and mobile devices. To make an inform decision, we can point to the research results from the World Health Organization (WHO) and the National Institute of Environmental Health Sciences (NIEHS).

Quote from the World Health Organization (WHO):

Conclusions from scientific research
In the area of biological effects and medical applications of non-ionizing radiation approximately 25,000 articles have been published over the past 30 years. Despite the feeling of some people that more research needs to be done, scientific knowledge in this area is now more extensive than for most chemicals. Based on a recent in-depth review of the scientific literature, the WHO concluded that current evidence does not confirm the existence of any health consequences from exposure to low level electromagnetic fields. However, some gaps in knowledge about biological effects exist and need further research. World Health Organization (WHO) http://www.who.int/peh-emf/about/WhatisEMF/en/index1.html

Quote from the National Institute of Environmental Health Sciences (NIEHS):

Because the use of electric power is so widespread, humans are constantly exposed to electric and magnetic fields. Studies conducted in the 1980s showed a link between magnetic field strength and the risk of childhood leukemia. After reviewing more than two decades of research in this area, NIEHS scientists have concluded that the overall pattern of results suggests a weak association between increasing exposure to EMFs and an increased risk of childhood leukemia. The few studies that have been conducted on adult exposures show no evidence of a link between residential EMF exposure and adult cancers, including leukemia, brain cancer, and breast cancer. Based on these reviews, the NIEHS recommends continued education on practical ways of reducing exposures to EMFs.

At this time, the US doesn't have any specific standards for EMF levels because most studies were inconculsive. in the 1990s The International Commission on Non-Ionizing Radiation Protection (ICNIRP) set the following guidlines:

Occupational (working place):
5,000 mG
50,000 mG
General Public:
1,000 mG
10,000 mG

Crystal Sauna EMF Readout

Using a digital EMF meter, we measured the EMF reading inside our sauna from one inch and six inches away from the heaters. Below is the EMF meter readout:

Far Infrared Technology
Standard heaters on all our saunas.
19.2 mG
7 mG
13.5 mG
Upgrade option avaliable for the Luxury, Family and Outdoor saunas.
2.4 mG
0 mG
1 mG

Pictures of EMF Readout

The pictures below are for measurement using a digital EMF meter from 1" away from the heaters (around the wooden frame surface). We measured in both vertical and horizontal layout to make sure the readout is accurate. Please note that measurement inside the sauna might be a bit different because of the wiring and heaters layout.

We also measured the PureCarbon EMF readout when using a backrest (about 5" away). The heaters pictures are a 5-picture collage to save space. We used the largest heaters we have (25"x41") at 120 volts for testing.

For comparison purposes, we also measured a computer power cord, an extension cord and a laptop.
