Infrared Sauna FAQ's

What is Infrared? 
Infrared (IR) radiation is electromagnetic radiation of a wavelength longer than that of visible light, but shorter than that of radio waves. The radiation penetrates the body and heats through a process called conversion, instead of heating the air around you.

Infrared light, as radiated by the Sun, lies between the Visible and Microwave sectors of the electromagnetic spectrum. 

What is an Infrared Sauna? 
An infrared sauna is a sauna that heats its occupants with heaters that emit far infrared radiant heat. Unlike traditional Finnish Saunas, infrared saunas do not use steam, (which heats the air, and thereby the user) but instead use infrared radiation to directly heat the user.

In an infrared sauna, the infrared heater produces radiant energy, which is the same as the heat from the sun, only without the harmful ultraviolet rays. Most of these heaters draw on technology developed in 1965 by Dr. Tadashi Ishikawa, a member of the Research and Development Department of Fuji Medical. 

The experience of a far infrared sauna is similar to sunbathing, which gives you the radiant heat that is all your own. The far infrared heat penetrates your skin, giving you that wonderful natural warmth. Unlike sunbathing, Infrared heat therapy is completely healthy and safe. You can relax in a far infrared sauna and it will never cause your skin to burn. Far infrared heat is completely healthy and safe for all living things. In fact, far infrared heat is so safe it is used in hospitals to warm newborn infants.

Are Infrared saunas safe to use?

Infrared saunas use safe and effective radiant heat just like the sun's soothing warmth. Radiant heat is more efficient because it warms you, not the air around you. Your body directly absorbs as much as 93% of the heat generated by our Carbon Fiber heaters. 

Far infrared radiation (FIR) is considered harmless for human. Infrared heaters are even used to heat premature babies in hospitals incubators. But some people with certain illnesses and conditions should not use an infrared sauna or should use it with great caution. 

The infrared radiant waves penetrate the body's tissues to a depth of over one and one half inchs. Its energy output is tuned to correspond very closely to the body's own radiant energy that our bodies generate.

At what temperature setting should I have the infrared sauna?

The recommended temperature is between 120 and 140 F. If a sauna is following safety guidelines, the temperature control will not allow settings above 140 F, beware otherwise.

How hot will the sauna get? How long does it take to heat up my infrared sauna?

Your Infrared sauna operating temperature will vary depends on the room temperature. Generally speaking, if the room temperature is over 64°F the operating temperature should be between 122-140°F. The sizes of the saunas play a major role in how fast the sauna can reach certain temperature. Average pre heating time is 30-45 mins, while a 4 person corner unit could take a little bit longer than a 2 person sauna.

The ideal temperature for an infrared sauna is between 110°F to 130°F. Remember, temperature is not important; the fact that you are receiving far infrared heat is.

Here is a helpful tip for getting the most of your infrared session:

First of all, once the sauna reaches the temperature set by the user,the heaters will not work at full capacity because they will cycle on and off once they reach their set temperature. We recommend that you start using the sauna before it reaches the set temperature in order for you to get the most infrared benefits and to maximize the output of the heaters.

If you set the sauna to 130(an ideal setting), then you should start using it around 115 or 120 while the heaters at full capacity, you will sweat more this way. Another option is to set the sauna to maximum temperature setting of 140 which will make the heaters operate at full capacity most of the time, you may not reach 140F during your sauna session but that is not important, getting the most infrared benefits is more important.

How long should I sit in an infrared sauna? 
Not exceeding 40 minutes at a time.

Can my children use the infrared sauna?
If they are supervised at all times, yes. The sauna can get very hot and people, especially little ones, can become dehydrated. CHILDREN SHOULD NOT USE AN INFRARED SAUNA UNSUPERVISED.

How much electricity does an infrared sauna use?
You can operate an infrared sauna for just a few cents per session.  They are quite energy efficient.

What does the air ionizer work?
O3: emits O3 to kill Bactria in the air. When you turn this on, it will change automatically into Ion after 15 minutes. We recommend this setting before and after using the sauna.

Ion: this setting traps and kill Bactria inside the ionizer, we recommend using this setting while using the sauna.
 
How should I clean the inside of my sauna?

Please do not use any chemical cleaners inside your sauna so as to avoid any toxic off-gassing. The inside of the sauna for this very reason, we want to avoid any off-gassing. You can use a damp cloth to wipe off any sweat. You can also lay a towel down over the bench to soak up sweat duing your sauna session.

What heaters do your suanas have? What are the differences between them? 
Our saunas feature Carbon-fiber heatesr. Carbon-fiber heater is an upgraded technolegy that emits more even heat distribution at a lower air temperature which means you can lean up against the heaters and venevr burn yourself. This is not the case with ceramic heaters which can get too hot to touch. View the differences between Carbon Fibre and Ceramic heaters

When ceramic heaters get too hot, a lot of energy will be converted into light (when they glow red) which reduces the infrared rays. That’s why most ceramic heaters have an emission rate of about 60%.

Carbon fiber heaters have a low surface temperature and 95% of the energy is converted into infrared since they never get too hot

What about EMF? Electromagnetic Field and Infrared Saunas

Infrared waves are part of the electromagnetic spectrum produced by the sun or any significant method of burning or other production method (such as electrical power).  Infrared waves are on the low end of the spectrum where the wavelengths are long and less intense.  Infrared waves are just below those of visible light.  They are “gentle” waves that give off heat.  Electromagnetic waves that are dangerous to humans, plants, and animals are those in the upper end of the spectrum, such as ultraviolet, x-rays, and microwaves.  The wavelength is closer or tighter and more intense.  Any of these wavelengths in moderation are generally safe to humans, plants, and animals; it is with prolonged exposure that damage occurs.  Electromagnetic fields in areas of high frequency and intensity (such as around high voltage power lines) are dangerous.  Infrared Saunas produce only the gentle long waves of the electromagnetic spectrum.  They do not produce EMFs in any significant amount.  You would receive more EMFs to your body from watching television or by using your microwave than you would ever receive from your Infrared Sauna.

What does Evolution Health do to reduce EMF in their saunas?
The easiest way to shield EMF is to cover electricity flow with metal. Evolution Health saunas uses steel conduits around its wiring within the walls of our saunas. On the carbon heaters themselves, however, a metal covering would also block the infrared waves. Because Evolution Health saunas emit an insignificant level of EMF, they are left uncovered for maximum far infrared output


ZERO EMF Heater upgrade option for Luxury Saunas:

Evolution Health Far Infrared Saunas fo not emit a significant level of EMF's, only 19 Mg from an inch away; flourescent lights emit far more at 40 Mg from just 6 inches away. We do have Zero EMF heaters available as an upgrade for those with MCS (multiple chemical sensitivities or for anyone who just want to lower their overall exposure to EMFs). The Zero EMF Heater upgrade is available only for our Luxury Series saunas
.

Standards

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):

Working wholeday: 5,000 mg
Short term (up to 2 hours): 50,000 mg

General Public:

Up to 24 hours per day: 1,000 mg
Few hours per day: 10,000 mg


EMF Readout

Heater Type 1" from the heaters
6" from the heaters (using the backrest) Average
PureCarbon
Avaliable on all our saunas
19.2 mg 7 mg 13.5 mg
ZeroEMF
Upgrade available for the Luxury Series
2 mg 0 mg 1 mg


Here is a summary of devices in your home that have high levels of EMFs even when you are several feet away:

Computers

The Swedish safety standard, effective 711/90, specifies a maximum of 0.25 mG at 50 cm from the display. Many US manufactured computers have EMFs of 5 - 100 mG at this distance. 

Electric Clocks

Electric clocks have a very high magnetic field, as much as 5 to 10 mG up to three feet away. If you are using a bedside clock, you are probably sleeping in an EMF equivalent to that of a powerlines, it is wise to place all clocks and other electrical devices (such as telephones and answering devices) at least 6 feet from your bed.

Fluorescent Lights

Fluorescent lights produce much more EMFs than incandescent bulbs. A typical fluorescent lamp of a office ceiling have readings of 160 to 200 mg 1 inch away.

Microwave Ovens and Radar

Microwave ovens and radar from military installations and airports emit two types of radiation -- microwave and ELF. Microwaves are measured in milliwatt per centimeter squared (mW/cm2) As of 1/1/93, the U.S. safety limit for microwave exposure is 1 mW/cm2, down from a previous 10 mW/cm2. The Russian safety limit is .01 mW/cm2. All microwave ovens leak and exceed the Russian safety limit. In addition, recent Russian studies have shown that normal microwave cooking coverts food protein molecules into carcinogenic substances.

Telephones and Answering Machines

Telephones can emit surprisingly strong EMFs, especially from the handset. This is a problem because we hold the telephone so close to our head. 

Some brands emit no measurable fields and others emit strong fields that travel several inches....right into your brain. Answering machines, particular those with adapter plugs (mini-transformers), give off high levels of EMFs.

Electric Razors and Hair Dryers

Electric razors and hair dryers emit EMFs as high as 200 to 400 mG.


Where are the infrared saunas made? 
They are made in China. There are only a couple of Infrared Sauna manufacturers in the US. There saunas are priced very high and they only seem to offer ceramic heater saunas, often twice as much as our high end Fiber Carbon Infrared Saunas.
The saunas that we offer are manufactured by reputable companies in China with a long history in the business and a strong safety record.

From what wood are the infrared saunas made?

Our Infrared Saunas are made of 100% Canadian Hemlock-Fir. Hem-Fir is a perfect combination of strength and extraordinary beauty and is quite literally one of the most handsome, elegant and versatile softwood species combinations on the market today. Hem-Fir lumber is light and bright in color, varying from a creamy, nearly-white to a light, straw-brown color. Hemlock is also quite sturdy and resistant to warping.

Is the wood chemically treated?

The wood we use is not chemically treated. We kiln dry the wood to cure it. The US requires wood for constructions purposes to be chemically treated (such as hardwood floor, plywood sheets, etc). For furniture (including saunas), the wood can be kiln dried, steamed or heat treated.

Is Hemlock/Red Cedar a "flawless" wood?

Our saunas are a natural wood product. There may be knots, color variations, and even small cracks in the wood. This is a natural part of the drying process that occurs in wood, especially where heat is involved, as in a sauna. These things are normal in a natural wooden sauna, and are in no way indicative of poor quality, and will in no way affect the performance of your sauna. It is suggested when you put screws into the wood of your sauna (as in when you install the accessories and back rest) that you pre-drill pilot holes to avoid splitting. 


What is your return policy?


See the return policy for our Luxury, Deluxe, or Basic Series saunas


How are the infrared saunas shipped?
  • Our saunas are shipped via freight (on a semi truck).  Normal shipping time in the US is 5-7 business days.  We provide tracking information via email when your sauna ships, and the freight company should call you prior to delivery to set up an appointment window.  You must be there at the time of delivery to inspect, sign for, and help unload the sauna from the freight truck. Please note the driver, although not required, will usually unload the sauna from the truck and deliver to your front door. Our Basic, Deluxe luxury, outdoor, and carbonwave360 saunas come with liftgate service so the driver will unload and deliver to your front door.

    Please let us know of any special circumstances beforehand, ie, you live in a mobile home park,so we can notify the freight company.
Will the driver set it up for me?

No.  Fortunately, installation is not that complicated! If you would like to have White Glove delivery (they will set up the sauna and discard the boxes) you can add that if ordering one of the West Coast Saunas. Note: not available for the Deluxe, basic, luxury or outdoor saunas.

I need a replacement bulb for my reading light! What should I get?

  • You need a Halogen light - 35W, 110V, Model MR16.  Please be aware that the MR16 is available in several voltages.  You must have a 110V bulb, or it will burn out very quickly. 

What is the infrared sauna warranty?

What are the Contra-indications for Infrared Saunas?

  • If you have a disease, be certain to consult with a primary-care physician concerning it.
  • If you are using any prescription drugs, check with your physician or pharmacist for any possible change in the drug's effect due to any interaction with infrared energy.
  • It is considered inadvisable to raise the core temperature in someone with adrenal suppression and systemic lupus erythematosus or multiple sclerosis, by some authorities.
  • If you have a recent (acute) joint injury, it should not be heated for the first 48 hours after an injury or until the hot and swollen symptoms subside. If you have a joint or joints that are chronically hot and swollen, these joints may respond poorly to vigorous heating of any kind. Vigorous heating is strictly contra-indicated in cases of enclosed infections be they dental, in joints or in any other tissues.
  • If you are pregnant or suspect you may be, discontinue your sauna use. Finnish women use their saunas, which don't throw heat as deeply into the body, for only 6~12 minutes and reportedly leave at that time, due to perceived discomfort. Their usage at this low level of intensity is not linked to birth defects. Infrared Thermal System usage may be 2~3 times more intense, and comparatively shorter 2~6 minute sessions hardly seem worth any minimal risk they may present.
  • Metal pins, rods, artificial joints or any other surgical implants generally reflect infrared rays and thus are not heated by this system, nevertheless you should consult your surgeon prior to using Infrared Thermal System. Certainly, the usage of Infrared Thermal System must be discontinued if you experience pain near any such implants. Silicone does absorb infrared energy. Implanted silicone or silicone prostheses for nose or ear replacement may be warmed by the infrared rays. Since silicone melts at over 200°C (392°F), it should not be adversely affected by the usage of Infrared Thermal System. It is still advised that you check with your surgeon and possibly a representative from the product manufacture to be certain.
  • Heating of the low back area of women during the menstrual period may temporarily increase their menstrual flow. Once a woman is aware that this may occur, she can choose to allow herself to possible experience this short term effect without worry or to simply avoid Infrared Thermal System usage at that time of her cycle.
  • Hemophiliacs and anyone predisposed to hemorrhage should avoid Infrared Thermal System usage or any type of heating that would induce vasodilatation, which can potentate the tendency to bleed.
  • Obviously, should any condition worsen with use of an Infrared treatment, the use of the system should be discontinued.
  • People do not experience pain using Infrared Thermal Systems unless such is contraindicated. If you do, the use of radiant heat is clearly inappropriate for you at that time.
  • DO NOT attempt to self-treat any disease with this Infrared Thermal System without direct supervision of a physician.
