Far Infrared Saunas
Far Infrared Sauna
Hothouse Dome from HTE.
Invented in Japan in 1988.
Infrared Saunas - Introduction:
are many far infrared (FIR) units on the market
which is very confusing to the public. This page
will explain how they came into existence and the
differences between them. This is important so as
not to spend a lot of money on something that will
not give optimal far infrared benefits as expected
and desired, especially if intended for specific
use as thermal therapy.
HTE (Hsin Ten
Enterprise), was the first company to
introduce a Far Infrared sauna unit to the
public in North America in 1997. The unit was
invented in Japan and is called the Far Infrared
Hothouse Dome. The traditional sauna companies
took note of this far infrared 'dry' sauna and
shortly thereafter followed suit by incorporating
far infrared heat into their existing set-up.
Source of Far
Infrared Rays and the difference between wet
and dry heat:
Traditional saunas introduced
carbon coated metal rods or carbon coated ceramic
plates into their existing sauna units to generate
far infrared heat and then renamed and marketed them
as far infrared sauna even though they remain a
traditional sauna generating a hot 'wet' heat.
A traditional sauna
uses heat to warm the air, which in turn heats up
your body. This is a 'wet' heat which therefore
requires you to remove your clothes.
A far infrared sauna
heats your body directly, without warming the air
around you. Far Infrared is a 'dry' heat, clothing
is optional. There is no sweating involved - toxins
are released through the urine and feces.
None of the
traditional 'infrared sauna' (or the copycat far
infrared sauna domes) use the same advanced unique patented crystal
chip surface as the Far Infrared Hothouse
Dome which emits 100% pure far infrared. Most far
infrared saunas emit 40% to around 90% far infrared
(very few units reach 90%). Some far infrared sauna
units generate too much wet heat and thereby
dramatically reduce the actual far infrared emission

No-one has duplicated this advanced technology.
Sources used to generate far
infrared by traditional ' far infrared' saunas:
* Carbon panels or plastic
carbon sheets mixed with bonding glue.
* Carbon coals.
* Carbonized steel metal rods.
* Ceramic coated metal rods.
* Aluminum plate with ceramic coat.
* Small flat and un-reflective ceramic plates
* Plastic, ceramic or aluminum heaters
* Chemically treated wood and glues.
* Foldable synthetic material enclosure - wire and
* Fiberglass domes - carbon.
* Precious stones such as Amethyst or Jade.
* Carbonized wiring.
Glue produces toxic fumes - Ceramic will crack and
break in half - Metal rods and wires can generate
too much heat - aluminum is a very deadly toxin.
When you compare these different sources used to
generate the far infrared, it is disturbing how
potentially toxic they may be, and therefore quite
serious to consider choosing one that will benefit
your health and not harm it.

comparison of the original versus the
traditional saunas and copycat domes.
Many far infrared saunas and copycat
domes do not radiate the correct micron far infrared
ray wavelength which is 8-10 microns (7-14
is acceptable), being the most beneficial to the
human body. Many are less than 5 microns (towards
medium infrared ray range) or way beyond 14 microns,
which is not physically beneficial.
Initially, most infrared
sauna companies did not understand what is a micron,
so many companies simply copied or re-wrote the far
infrared data and information from the Far Infrared
Hothouse Dome because scant information and
documentation was available at that time written in
Australia, exclusive distributors of the Far
Infrared Sauna Hothouse Dome, published a book
specially translated into English for the company -
"The Scientific Basis and Therapeutic Benefits of
Far Infrared Ray Therapy" written by Yamazaki Toshio
in Japan. Nearly all the traditional far infrared
sauna companies have had the audacity to copy quotes
from the book to their websites, taken from this
website. The book is not available in bookstores and
was not intended to be applied to traditional sauna
Most units weigh three times more than the Far
Infrared Hothouse dome sauna which is only 13 lbs -
UP TIME: Many units require 10-20
minutes minimum warm up time.The FIR Hothouse dome
sauna heats up immediately.
RANGE: Many have temperature ranges
that fluctuate dramatically. The FIR
Hothouse dome sauna heat is set and constant.
Many far infrared sauna pose the danger of
overheating and dehydration, air temperature can
become unbearable. The Far Infrared Hothouse dome
sauna poses no such danger as overheating of the
user does not occur. The gentle far infrared ray
penetrating the body feel more like the 70's
temperature wise. The pure far infrared heat of the
Hothouse dome does not cause hydration, unlike a
closed, intensely hot traditional sauna does.
1) Many do not have an electronic thermostat or
overload shut-off for safety. The FIR Hothouse dome
sauna has a built in regulator.
2) Most of the ceramic heaters
have some kind of protective face guard because they
are so hot that if you accidentally touch them you
will get hurt. The Hothouse dome surface will not
cause this to happen as it has a silicone crystal
Traditional sauna units have the source
of far infrared too far away from the body to
have optimal impact. The far
infrared emitter surface should
be as close to the body as possible.
The Far Infrared Hothouse dome is within inches of
A traditional sauna wooden box
unit which people sit in, is hard pressed to provide
optimal Far Infrared benefit as the source of far
infrared being emitted is not within inches of the
body, but feet. The further the body is from
the Far Infrared waves, which travel in straight
lines, the lesser the impact and benefits.
DEVICE: The Hothouse dome far
infrared sauna is officially
classified and recognized as a medical device
in four countries,
including Japan, Australia, Canada where such classification is
very hard to obtain.
'One size fits all' copycat igloo saunas, do not
typically accommodate larger bodies. The Far
Infrared Hothouse dome sauna comes in two sizes to
accommodate bodies below or over 180 lbs, the latter
is known as the Grande Hothouse Dome.
Many far infrared saunas, especially the
traditional saunas, are considered unsanitary due to
sweating and require clothing removal. You do not
have to remove clothing under the Hothouse dome.
a) The correct term is FAR INFRARED. Near
Infrared units are a completely different
healing modality which incorporate light therapy
from colored light bulbs, which penetrate 3-5
b) Far Infrared rays penetrates the skin
about 2 to 2 1/2 inches - not 4 or 5 inches as some
traditional sauna claim.
c) Far Infrared Ray
should ideally be 8-10 microns to benefit the human
body. Many traditional units are above 11 or
below 7 microns so there is less to zero benefit, as
the ray are no longer Far Infrared because they move
into different spectrums, microwave or mid-infrared.
d) Traditional far
infrared sauna imply the entire body is bathed in
Far Infrared. In fact the units have only a few
scattered sources emitting far infrared ray. Apart
from being too far away from the FIR source to
benefit the body, traditional far infrared saunas
simply miss the human target, or are absorbed into
the wood which benefits no-one.
Electro magnetic frequencies (EMF),
is beginning to be understood by the public. EMF
with consistent, regular doses, has been proven to
be harmful. Cellular phones when consistently used
next to the head, cause brain tumors, or if
continually carried in the trouser pocket, may
trigger prostate cancer. A cell phone radiates
extremely damaging EMF to the bodies cellular
structure, intensified by the close proximity on a
daily basis, and the accumulation of long term
EMF is a concern for
traditional saunas, some of which emit high levels.
The fact is, far infrared heat negates the negative
effects of EMF, and some far infrared saunas
may radiate far less than that of a cell phone.
Check and be sure the EMF frequency of any far
infrared unit you consider is low, that the far
infrared ray are concentrated - between 7-14 microns
- and that the far infrared rays are in close
proximity to the body.
You will NOT lose serious weight using far
infrared saunas, if at all. Traditional Far Infrared
heat therapy in Asia and Europe is used for relief,
reduction and removal of pain, swelling and
inflammation, serious elimination of toxins (such as
heavy metals, drugs, pesticides, chemicals etc),
improved circulation, accelerated healing, tissue
regeneration, relaxation and other healing
