Shielding Smart Meters

Smart meters are becoming more common in today’s world and can be found on most if not all of your utilities (water, gas, and electric).  They have evolved because in short, people demanded them.  Customers don’t want to pay more for any of their utilities, but they want the companies to fix problems as soon as they happen.   Customers also want to know how they can limit their costs and so monitoring usage is necessary.  This used to be done with PLC (powerline communications), but this software has become dated.  This means upgrades and maintenance which costs more money.  The increased use of wireless signals makes smart meters more cost effective for companies and because of that it means a little bit cheaper bill for customers.  Many customers don’t even realize smart meters are there.

This article is for the people that do have issues caused by RF signals and walks you though how to handle them.  When dealing with smart meters it is important to understand which kind you have and how often it transmits a signal.   For meters that only transmit a signal once a day or less, I don’t bother with shielding, but many smart meters will transmit every 6 seconds.  These are the meters I look to shield.

Once you have located the meter and determined the interval of transmission, the next thing to do is shield it.  With gas and water meters, this is quite simple.  All you will need to do is wrap aluminium foil around the meter.  I normally do this 3-4 times or based on the reading on the RF meter that I am using.  When completed it looks something like the picture below.

water meter

With this shielded, the local water utility personnel can’t get a reading from the street, so when they come to take their readings, I remove the foil and then reapply it.  They take a reading once every three months.  Lately they have been calling when they are in the area, and I leave it un-shielded for a day and then re-shield for the three months they are not monitoring it.

Smart meters that are located on the electrical panel are a bit harder to shield.  Really when shielding these, it is a two step process.  The first step is to shield the meter itself like in the picture below.  Again, I just used aluminum foil and duct tape.

smart meter

I formed the foil around the glass part of the meter 4-5 layers thick.  This will decrease the signal, but it will not completely block the signal.  The utility likely will not be able to pick up the signal.  The back side of the utility box will also act as a shield since it is made of metal, however you still should account for reflection.   Shielding the rest of the signal that is coming off the meter and going into the house is necessary.  It is also important to have the inside wall shielded so if the shield on the outside is taken off, or falls off, you will still have some shielding in place.  To do this you will need to shield the wall on the back side of the meter.

Locate the inside room in your house where the meter attaches to the wall.  For our home, it is the where the box is in the photo below.  beforewallPNG

There are many types of shielding products that will work for reducing/blocking RF signals caused by smart meters.  The one I chose was a Mylar blanket.  You can find these in the camping section of a sporting goods store.  A 4 x 6 ft blanket will run you less than $5 per blanket.  These blankets are thin so you may need more than one.

Using just double stick tape on the back side of the blankets, I adhered them to the wall.  I had them all overlap where the box was located on the wall in the picture below.  This will do a couple of things.  One, it will add more shielding where the signal will be strongest.  Second, it will reduce the signal that would otherwise go into my son’s room adjacent to this room.

At this point, you could leave the wall because it is shielded, however it is not aesthetically pleasing to look at.  This is where doing an accent wall comes into play.  We used reclaimed redwood and the finished product is in the picture below.


It is important to note that with an electrical box there are 2 issues.  One is the RF signal that comes form the potential smart meter (which we just shielded), but the other is a magnetic field  that would be in the area of the box in the picture above.  Since your electrical panel is located directly below this, there is a a magnetic field generated from that.  There is shielding that you can use for magnetic fields, however it is much cheaper to move away from the problem area.  YOU SHOULD NEVER PLACE A BED OF ANY KIND IN AN AREA WITH A MAGNETIC FIELD.  This is especially important for small children and infants.  You are looking at placing any type of sleeping area at least 6 ft from the source, because at that distance the magnetic field will be greatly reduced (to the point of the ambient field in most cases).  In our house, shielding the RF signal was enough because this room is used as an office.  We place ourselves out of the magnetic field as far as possible.  In the future, we could use this as bedroom, but would just need to be mindful of where the bed was placed.

The total cost for this DIY project was around $450.  This doesn’t include the tools needed to do the project, only the materials.  The breakdown of materials was about $20 for the shielding material (used 4 blankets) and the rest was redwood shiplap.



When do you buy shielding?  Does shielding work?  Should I buy shielding for my home?  These are questions that come up a lot.  Many people that are worried about the effects of being exposed to EMF’s have bought some type of shielding.  There are many items that will shield you from some aspects of EMF’s.  Today we are going to talk about a few items that block microwave frequencies.

How does shielding work?

Most of these items are made in a similar way.  You take a piece of cloth and then you line it with a conductive metal.  Many times this metal is silver.  The lines of thread are then woven together and the result is a basic Faraday cage that mitigates microwave frequencies.   These items are good at blocking these frequencies, but this is not the whole picture.

When should you get shielding or where should you have shielding?

If you are in an area that has a lot of wireless activity, or find yourself next to towers that you can can’t do anything about, then this is when you should consider shielding.  The most cost-effective place to shield is your bed.  This is for a few very important reasons:

  • You are in the same spot for many hours a night
  • Night time is when your body heals
  • A good nights sleep is an important part of health

We live in an area that has a lot of wireless activity and because of my sensitivities I purchased a canopy as pictured below.    This is the set up that we were using for a long time.  For the record, this is wrong.  We were doing this wrong because we were only looking at one side of the problem.  I will explain.



With this setup, many times during the night, we found different parts of our body (feet, hands, arms, or head) touching the canopy.  This is where the problem is.  Items that block microwave frequencies will do so, and the higher concentration the more it will block.  This is where we failed.  By touching the canopy that is blocking wireless frequencies, it gives that energy someplace else to go, which is into your body.  This is also referred to as contact current.  By mitigating one problem we created another problem.

Key point in shielding: You should not allow the shielding to touch your body.  If you are inside of the shield you are fine. 

In our instance we had contact current passing through as shown by the picture below.  Anything above 18 microamps is considered bad and harmful as can be read here.  At 127 microamps you need to do something.  The question is –which is less bad? To be exposed to wireless frequencies or 127 microamps of contact current?   I honestly don’t know.  So I took down the canopy to try and find out which is worse for me by judging how I slept at night.   Over time I noticed that my quality of sleep started to suffer.  I was not as rested.  I was less patient.  I needed to try something different.  I had to go back to the drawing board.


What we needed was a way to create a defined space for the netting that we would not come in contact with while we slept.  The solution was a four post bed made of wood (not metal because metal is conductive).



Now with our bed we are able to set up our netting without coming in contact with it for long periods of time.  This has led to better sleeping for both my wife and I.   This was something special that needed to be made and we couldn’t have done this without Nordic Custom Woodworking (Eau Claire, WI).  Now we not only have a great looking bed, but we also have something that supports our netting in a functional way.  This in turn has provided us with better sleeping and most importantly we are not coming into contact with the netting in our sleep.

The other option to deal with shielding is to have it grounded.  However you MUST keep in mind that in most cases ground is not zero.  There is contact current there and so by attaching yourself to ground, you can increase your contact current.  This defeats the purpose of grounding.

Here are some key things that you should take away from this:

  • If you are going to shield from wireless that you cannot control, the most cost-effective method is to shield your bed.
  • By grounding the shielding, you could could increase the contact current present
  • Do not use any shielding that will touch your skin because you will increase your contact current.  This includes items like shielding blankets/sheets, shirts, hats, or any other clothing. If you use a canopy, make sure you do not come in contact with it in your sleep.
  • Bed frames should be made of wood and not metal
  • Metal is conductive and is an antenna for wireless so wear as little metal as possible. This would also include excessive jewelry and metal in under-wire bras



Magnetic Fields and Miscarriages

Recently there was a research paper that found higher rates of miscarriages based on an individual’s exposure to magnetic fields which you may read here.   In this paper they found that you have an almost 3 times (2.72) higher chance of a miscarriage by being exposed to a magnetic field of more 2.5 mG for more than 14 minutes.  Another paper that had similar findings found that women that were exposed to a field of over 16 mG had a higher chance of having a miscarriage, which can be read here.

Fields of this magnitude are not difficult to find in a common home.  Below lists some electrical items that can create fields of 2.5 mG, or items that can create fields larger than 18 mG.  Many of these items are commonly used for greater than 14 minutes at close proximity.

Electric Blankets

Electric Space Heaters

Hair Dryer

Electric Toothbrush

Electric Razors

Massage Chairs

Electric Saunas

Motorized Beds

Alarm Clock Radios

Electrical Utility Panels

Electric Cook-tops

Convection Oven

Conventional Oven


Plasma TV’s

Small Fans

Kitchen Appliances

Electric Power Tools

Computer Desktops

Wiring Errors in the Home

Just because you have something on this list doesn’t mean you have to get rid of it.  Many of these items you can still use by simply creating a safe distance.  The farther away you are the less the field will be.  In the case of wiring errors, these you can fix.



What is Dirty Electricity?

When we talk about clean power we are referring to how perfect the Sine Wave is.  How much distortion is being caused by harmonics?  What the total harmonic distortion (THD) is.  The IEEE (Institute for Electrical and Electronic Engineers) has standards for THD which can be found in the IEEE 519.  The basic, short version is that standard power that is supplied to your home will have no more than 5% harmonic voltage distortion with the largest single harmonic being no more than 3% of the fundamental voltage.   If you are shopping for inverter generators this is sometimes mentioned as a selling point if they have really low THD.  Inverter generators have other issues as described in this blog post.  What the Microsurge meter does is quantifies the THD in your home by analyzing what frequencies are present in the THD.  If you have an oscilloscope reading, then you have a much better break-down of which frequencies you are dealing with that make your THD.

On this page you will be find many before and after pictures of graphs that show a reduction in frequencies on the building wires after installing Stetzerizer Filters.  The frequencies that are reduced or eliminated are the ones that range from 4 kHz to 100 kHz (which the filters are designed to filter because they are biologically active frequencies).   People who are electronically sensitive will react to this frequency range on a building’s wires. You can find these frequencies in almost every building in America; the only exception being those buildings that have filters plugged in.  These frequencies are created primarily by the electronics that we have which include but are not limited to: switch mode power supplies, computers, certain light bulbs, variable frequency drives,  game consoles, Blue Ray players, and generally anything that uses a non-linear load.  Non-linear loads are pretty much found in all the electronics and ‘green items’  that you have in your home today.

The first step in dealing with any problem is getting a measurement of how bad it is.  Measure first to find out what your levels are.  To do this, you will need a device like the Microsurge Meter.  The higher the number on this device, the worse it is.   To reduce this number you simply plug in filters where you need them (you will not need one in all of your outlets).  To order a Microsurge Filter and filters with instructions to fix your home, click on this link.


Understanding the Triggers

The last time that I thought of killing myself I was 22.   I chambered a single hollow point round in my pistol and clicked off the safety.  Over the next hour or so I made a pro’s and con’s list of why or why not be here anymore.  This was not the first time I thought of killing myself, nor even the first time I had a plan to end it or even took steps towards that plan.  It was though, probably the closest I came and the last time I thought about killing myself.

By this time, I had been on the fence for a while on whether or not to be here and decided that I can’t keep doing what I am doing.  Either I was going to end it, or I was just going to go on and deal with things.  I was in a bad place in many aspects of my life and it had finally come to a head.  In the end, it was not the pro and cons list I created in my head, or any of the aftermath that might come of my death that kept me here.  I realized through it all that I needed a reason to keep going.  I simply needed a reason to be here.  Something I could turn to and hang on to and use as my mantra when I needed it.  I found that reason and it has gotten me through a lot.  If you are in a spot like that, find a reason to hang on to, a reason to keep going.  Stopping will not make anything better, keep fighting.  After figuring out a reason I was in a better spot.  Depressed, but in a safer spot.  Since that afternoon ending my life has not crossed my mind.  I knew that at some point I should go and see someone.  I would a little more than 2 years later, I finally went to go get some help with my depression.

I was medicated at that point and the MD told me that yes, I was depressed.  After being on medication for a while I found that the side effects from the medication were worse than the depression for me, so I stopped my medication and figured I would just deal with it.  Depression was not new to me and so I figured I would just deal with it the best I could.  I have not gone back to the doctor for depression; I have managed it on my own since.  I try and deal with the issues that make me depressed, which is much harder because there are numerous issues.  I take one at a time.  Over the course of the next decade plus there were times the depression was worse, sometimes it was better, but it was always there.

Then Kyanna got cancer.

Then Kyanna died.

Death and depression go hand and hand.  Each can be cited as the cause of the other.  Neither are things that ever go away.  They are simply things you carry.  Sometimes the load is light and others days it can feel like it is crushing you.  There are many aspects of depression people don’t recognize or don’t acknowledge, however the depression that can come with the death of a child is not one of them.   When your child dies there is depression among a host of other emotions that will follow.  For me depression was not new just harder, for my wife it was new and hard.  There are days everything is going fine and then suddenly something happens that reminds you of your child and what you lost, things you won’t do, things you miss, a sadness you can’t explain.  Sometimes you can pull yourself out, some days you can’t.   For anyone that has lost someone they love they understand that these feelings are ongoing, they never end.  There has not or do I think there will be a day or hour that I don’t think about Kyanna.   She is the closest thing to me that I can’t see, I can only feel.  That can be hard to deal with.  Over time that weight can be unbearable.  I understand death and depression because I stood at that precipice many years before.  I understand why some choose to go over the edge.   After Kyanna died, Jeni and I talked and I told her of the last time I thought about ending my life and up until that point I don’t think I ever told anyone about it.  I think I hinted, but I never told anyone that story.  I told her and I told her that I would be here no matter how bad it got, I was staying here.  After all I had a reason to be here and it was as good now as it was then.  I told her why I was staying and hoped that she would stay here with me and she has.

After Kyanna died I started researching why.  How does a 7-year-old get brain cancer?  What I found was uncomfortable but at the same time explained a lot for me and my depression as well as how Kyanna got cancer.  EMF’s were not the sole responsibility of my depression; there are and remain to be many factors that go into that.  EMF’s can alter biological processes.    There are many studies that deal with EMF’s and depression.  Suicide rates rose with the electrification of the US as read here.  Suicide rates are higher in urban area’s than rural, which of course have higher exposures rates.  EMF’s have been shown to lower melatonin levels as can be read here which can lead to depression.   There  are other papers that cite that EMF’s can cause depression like this one.  These are just some samples of the studies that link EMF’s to depression know there are more.  As I tried to find answers to explain what happened to Kyanna, I found an answer to explain things in my life. The times that I was the most depressed correlated with being in areas of high EMF’s.  That has been consistent throughout my life.

By addressing the EMF’s in my life, I have been able to get a better handle on my depression.  Do I still have issues with depression?  Yes, but it is much better than it was.  My mood swings are less, I am not as tired all the time, I am less angry, I sleep better, and most importantly I feel.  I am not numb.  Depression is something that will always be there and so you do the best to limit it as much as you can and learn constructive ways to deal with it.  With EMF’s I am aware of them and take steps to deal with them, because of all the issues that make my depression worse this is the easiest to deal with.  I act and for someone with depression that can be very hard to do.

If you are wondering how EMF’s are affecting you try these simple three things:

  1. Turn off your phone. Only use it if you must, otherwise keep it in airplane mode with the WiFi and Bluetooth shut off.  If you need to use the internet do it from a computer with a wired connection
  2. Shut off your WiFi when you are not using it. This is especially true at night.  Unplug it or put it on a timer.  This also goes for all of your electronic devices.
  3. Shut off the breaker to your bedroom at night to reduce exposure to dirty electricity. Install filters in areas that you need to be when you are awake and things are turned on.

If you have noticed, these are the three things I tell everyone, because for most people these are their biggest exposures.  In the short term, you can fix these things with a little effort.  In the long term, you will need to make more sustainable choices.  When you get to that point, let me know and I will help.   Life is too short to feel terrible or to not feel at all.  Joy is out there, hopefully you have a reason to find it.

LED Bulbs


Recently I found myself needing to buy some LED bulbs. All of the bulbs, around my light bulb, were bought at Menards.  You should be able to find these at really any home improvement store.  These are the only ones that I kept. When I was testing to find the ‘good’ LED know that I ended up returning about 2 times the amount of bulbs that I kept.  If you are going to get any of these bulbs double check to make sure they are good.  Also make sure they are EXACTLY the same bulb as the one in the picture.

Like I have said before you will need to test LED bulbs to see if they produce dirty electricity.  The easiest way to do this is with a Microsurge meter, which can be bought here and instructions can be found here.

Camping and Inverters

With the weather getting nicer, camping season is just right around the corner for many of us.  For some this means pulling a camper behind you to your favorite destination or packing a tent to get away and relax.  This also means trying to figure out a way to power everything.  This was exactly my thought recently as I tried to purchase a couple different forms of power to take with us.  To my disappointment, I ended up returning both items.  Here is why.

Many people that go camping want power.  If you can’t plug into an outlet then you will want to bring the power with you.  This means getting a generator.   Regular AC generators can be rather loud and really take away peace and quiet that you want when you are camping.  This was my thought and so like many I looked to an inverter generator, which is much quieter.   After much research I choose a 2000W Inverter Generator made my WEN.  I choose this because it claimed the lowest THD which was at .3% at no load and 1.2% at max load.  Everything was fine until I fired this up and plugged in the Mircosurge Meter to take a reading.  The reading was over 2000 G/S units.  By plugging in two Stetzerizer Filters the G/S reading was still 500, which is a far cry from the 30 G/S units I was hoping for.  What does 2000 G/S unit look like?  Just take a look at the red in the picture below.   The area between the cursors represents a frequency of 20 kHz.

Inverter generator

The blue wave shown above is 60 Hz power, the same that runs in our homes.  The high red waveform is the high frequency that is riding on the 60 Hz cycle (blue wave).

Another item that I tried was a battery inverter.  In this case it was a Suaoki 220 Wh/20,000 mAh Portable Generator Power Source Power Supply.  When I plugged in my Microsurge Meter to test this, it gave readings of 1700 G/S and after adding two filters the reading only came down to once again 500 G/S units.  The waveform is shown below.   The area between the cursor is 33 kHz.

Battery Inverter

The problems shown for these two items are very common.  I was hoping to find an exception to the rule but I did not.  Since both of these items created very large amounts of dirty electricity I ended up returning both of these items.  It seems that when we camp now we will be doing so with less electricity, and possibly the way that we should have been doing it all along.

If you are wondering about your inverter generator,  or even testing your camper (since most campers have an inverter in them) all you would need to test this is a Microsurge Meter.    Simply plug in the meter and read the number.  The higher the number the worse it is.  To lower the number just add a filter in the plug in.  Test all the plug ins and add filters anywhere the reading drops more than 20%.  In our camper we have 5 filters plugged in.  You can purchase meters and filters by clicking this link.


Recently in my local newspaper there was an article about CFL light bulbs.  This can be read here.  If you have read this or have CFL’s in your home please take time to read this.

Using the argument that ‘because we have always done it so it must safe’ should never be made.  There is a reason we have done away with mercury filled thermometers.  Mercury is toxic at any level.  Even more toxic for pregnant women and children.  However, besides the mercury issue there are many more factors that make CFL’s toxic.  The mercury in them is just one.

All fluorescent lighting will give off a radio frequency because this is part of the process for them to make light.  If a person is standing near this type of lighting it will generate current within a person’s body the closer that you stand next to it.  The National Institute of Environmental Health Sciences recognizes that at 18 microamps biological processes relevant to cancer take place.  This is almost 1/1000 of what a regular outlet is rated for.  If you were to stand near a CFL you will be over this.  If you have one in a lamp by your bed or on your desk, chances are you are over this.  This can be easily measured with a voltmeter (FLUKE 187,189 or 287 can all do this) or you can even capture the waveform with an oscilloscope.  This is not the only radio frequency that fluorescents will generate.

Almost all fluorescent light bulbs and CFL’s will add a radio frequency back onto your building’s wires.  These are harmonics which can be called high frequency voltage transients, or easier referred to as dirty electricity.  This too is easily measured with either an oscilloscope or a Mircosurge Meter.   There are numerous research papers that talk of the health implications of being around areas that have high levels of dirty electricity.  Cancer once again is one, but there are many more.

In order, to achieve energy efficiency, we have gone from linear loads (primary used in the 70’s) to non-linear loads today.  The ubiquitous use of non-linear loads (all our electronics are non-linear) has also created issues for the utility companies.  The byproduct of achieving energy efficient products are harmonics which are normally left unaccounted for, mainly because of the belief that since it is a small amount it is ok.  These small amounts add up and what you are left with thus is ground current, (since neutral and ground are bonded).  In many places the primary neutral return is too small to carry the load.   The harmonics generated from all these devices are in the frequency of radio waves and it is possible then to pick these up with an AM radio, either one that is hand held or even in your car radio.  The buzzing sound that you hear in your AM radio or the reason that your AM station cuts when driving by power lines is due to our use of non-linear loads and ‘green’ energy.

If you are looking for energy efficient light bulbs look to LED instead.   Be careful though as many LED’s will also create dirty electricity.  You must test them to find out which ones don’t.

Making your cell phone safe

Today one of the biggest exposures to EMF in your daily life comes from the very thing that most people can’t stand to live without, their phone.  Ironically, there are a lot of people that realize that their phone might be doing something harmful to them.  In order to combat this there are numerous companies that have sprung up and claim that adding this or that to your phone will make your phone safe.  The real question is how do you make your phone safe to use?  This is where the paradox starts, because the truth is if your phone works, it is not safe.

EMF’s simply put are toxins.  Toxins at any level aren’t ‘safe‘.  EMF’s can damage DNA as Dr. Henry Lai found as far back as the mid 1990’s.   A  comprehensive paper written on the toxic effects of EMF exposure written by Dr. Neil Cherry can be read here.  The latest cell phone study done by the National Toxicology Program reports increased DNA damage as well.  The paper is expected by December of this year.

How can you tell if the little device that is stuck to your phone is doing anything?  Well it is pretty simple. Does the phone still work?  Can you call it?  If the answer is yes to either one of these, then sadly you have wasted your money.  If you are currently shopping for a sticker for your phone and in the marketing says ‘that will not alter the function of your phone’ then it would be best to keep on walking.  It would be very comparable to smoking a non filtered cigarette versus a filtered cigarette.  Yes with a filtered cigarette you are getting less tar and all of the other harmful things that are found in cigarettes, but the fact remains that you are still smoking.  Smoking is toxic just like EMF’s are toxic.

What can you do?  The best option is to give up your phone.  That is what I did, however this is something almost everyone is not willing to do.  The next best option is to use airplane mode on your phone or device as much as possible.  THIS IS FREE and built into the phone.   If you are unwilling to use airplane mode then the option becomes even more cumbersome and less effective.   Other options include wrapping your phone in aluminum foil.  This will of course drain your battery faster than normal.  The last option would be buying a metal Faraday Cage for your phone, and makes using your phone much harder.

If you have fallen for some device that you wear or have on your phone, you are not alone.  I fell for this too because like everyone that buys these items I wanted to make my phone safe.  Buying something and putting it on my phone made me feel safe.  That was an illusion.  The reality is that my phone still worked ,and I under the illusion that I was safe, used my phone and devices as much if not more instead of less.  The reality, I was making myself feel worse not better.  On top of that I was around my little girl that had stage 4 cancer, which certainly didn’t help and only made matters worse for Kyanna (Puzzle Series).




When it comes to mitigating EMFs (electromagnetic frequencies) you may come across the slogan “Low EMF”.  If you are wondering what that means, well your guess will be as good as mine. “Low EMF” is just a vague statement especially when no reference is given.  In reality, something that is labeled as “Low EMF” should be taken as lightly as the terminology or usage of the word “natural” in relation to quality of food.  The question then is what do you look for?  Here are some tips to help and some ways to test.

Low EMF can relate to many different fields or frequencies.  Knowing what is lower is the first key.  The second point to make here is that if it is lower then there should be a measurement to show testing before and after.  There are devices to measure all of the fields and frequencies, so you should be able to see these measurements.  If this is not stated, shown, or explained, then just keep shopping.

There are many items that are marketed as low EMF.  The common assumption is that this will make an item safe.  Please know that this is often not the case.  If you are wearing a pendent to block EMFs, or have something on your phone or tablet, know that these don’t make them safe, and in many cases it is questionable if they are doing anything at all.  Many people buy these items thinking they have made their device ‘safe’.  They have not.  The worst part is that in thinking they are now ‘safe’ they use the item even more, which is even more dangerous.

The easiest way to test the quality of a pendent or something you put on your phone is to simply try and use it.  If your phone still works then the item doesn’t work as well as it should and in my opinion you shouldn’t buy it.  What does work then?  Airplane mode works and is build into most all devices and it is free. It works.  Wrapping your phone in aluminum foil 3-4 times works.  Try that and then call the phone, it should go straight to voice mail.  If it doesn’t wrap it a couple more times.  Putting a device in an all metal container will also work as well as any type of Faraday Cage.   The best way to lower exposure is to not have a cell phone, but if you need one, please do one of the things mentioned above.

The sauna industry is a great example of an industry that recognized the harm of magnetic fields and took a proactive response to reduce them.  Infrared Saunas are used to help promote a healthy lifestyle and have many health benefits.  What is not a benefit is being exposed to high magnetic fields.  It is because of this that you will see some marketed as ‘Low EMF’.  What should low mean?  If the sales person or site that is selling the sauna doesn’t state what the magnetic fields are then just keep shopping.  When you do find this you are looking for fields that are less than 1 milligauss or .1 microtesla. Ideally these measurements should be taken in close proximity to the heating elements.  The ambient field within the sauna should be under 1 mG. This magnetic field level recommendation comes from the BioInitiative Report.
