Infrared Heat Therapy : Question & Answers
What is Infrared?
80% of the sun’s rays are infrared. Our atmosphere allows
IR rays in the 1 to 14 micron range to safely reach the earth’s
surface. Infrared rays are part of the electromagnetic spectrum
which also includes gamma rays, X-rays, ultraviolet, visible,
microwaves and radio waves. The only difference between these
different types of radiation is their wavelength or their
frequency. With increasing wavelength, the frequency, energy
and temperature decreases from gamma rays to radio waves.
Travelling at the speed of light these heat waves reach the
earth’s surface after the earth’s atmosphere has
blocked out the hazardous rays.
The electromagnetic spectrum can be divided into: 1. The Optical
Spectrum or the spectrum that is visible to the human eye.
It includes seven colours: red, orange, yellow, green, cyan,
blue and violet. Of the visible lights, red is the colour
having the longest wavelengths and violet the shortest. 2.
Invisible Lights outside the Optical Spectrum. These include
among various invisible light waves; Infra (meaning ‘below’)
red, and Ultra (meaning ‘beyond’) violet. Thus,
infrared light is ‘below red’ and ultraviolet
light is ‘beyond violet’.
In 1800, William Herschel, a German astronomer, while researching
the heat effects of the colours of the optical spectrum, found
that the temperatures in the colours increased as he went
from violet to red. Herschel also discovered that the temperature
continued to increase beyond the colour red, into a region
of invisible light which he named, “Infrared”.
Infrared lies between the visible and microwave portions
of the electromagnetic spectrum. Infrared waves have wavelengths
longer than visible and shorter than microwaves, and have
frequencies which are lower than visible and higher than microwaves.
Infrared is broken into three distinct segments: near, mid
and far-infrared differentiated by wavelength measured in
microns. One micron is equivalent to 1/1,000,000 of a meter.
Near-infrared is that part of the infrared spectrum that is
closest to visible light and Far-infrared is closer to the
microwave region. Mid-infrared is the region between these
What is Far
- 0.76 to 1.5 microns = Near Infrared
- 1.5 to 5.6 microns = Middle Infrared
- 5.6 to 1000 microns = Far Infrared
What is Infrared
- Far infrared (FIR) is part of the natural spectrum of
light energy emanating from the sun.
- Because of its specific (longer) wavelength, FIR heat
is directly transmitted onto object without heating the
air in between.
- FIR heat due to its physical properties has a deep
penetrating power. The radiant heat surrounds us and penetrates
deeply into our joints, muscles and tissues, speeding
oxygen flow and increasing circulation.
- When FIR comes in contact with the body, it is able
to penetrate well below the skin (up to 45mm), enabling
body to sweat at pleasant air temperatures of only 43-66ºC
- Because of its longer wavelength, Far Infrared is not
visible to the human eye. However, they can be seen by
special instruments that translate infrared into a variety
- Far Infrared is a natural form of light energy that
is safest of the rays. It should not be confused with
harmful ultraviolet radiation. FIR will not sunburn or
damage the skin or tissues below it. In fact, it’s
a normal heat that is absolutely essential for all living
things to remain tranquil, calm and healthy.
- FIR above all, provides numerous health benefits in
highly enjoyable and comfortable environment with absolutely
no side effects.
Infrared saunas are basically an incredibly healthy alternative to sweating in a gym or using an old fashion conventional dry heat or steam sauna. They use Far Infrared heat that emulates the sun. The high-tech heating elements move at the speed of light, penetrating human body 1.5 to 2 inches deep. This in turn shakes loose fat and frees toxins. The soothing FIR heat sweats away weight and calories many times more effectively than traditional sauna or even a workout!
Far Infrared Saunas also apply the ancient principle of
healing touch therapies for improved cell growth. They warm
the injury site to speed healing. Why is infrared heat better
than say, a heating pad? Because the vibrational energy
of FIR light is unlike that of the heat energy we use for
everyday functions, like cooking. Boiling water can damage
our skin and yet not heal internal organs. Sunlight heats
us in a profound way; however it includes along with the
far-infrared rays, the full range of energy in the electromagnetic
spectrum some of them dangerous and harmful. sauna-in-spa™
saunas provide only the optimum rage of FIR most suitable
for human consumption.
What is Optimum
Far Infrared frequency for an FIR Sauna?
Since the light and energy emitted by the sun that we perceive
as heat is actually Far Infrared Radiation (FIR), it is also
called thermal radiation or thermal light with wavelengths
measuring between 5.6 and 1000 microns. The far infrared range
of 7 to 14 micron range is the most beneficial. Human Beings
also emit energy at 7 to 14 micron range. With human body
and the ceramic infrared heaters on the same micron level,
FIR heat has no obstruction and can penetrate at the speed
of light. With good portion of wavelengths at 9.4 micron –
frequency at which a water molecule resonates or vibrates
– causes release of cellular toxins such as mercury,
aluminium, cholesterol, acids and other toxic gases –
resulting in beautification and fitness not experienced with
any other device.
How does a Far
Infrared Sauna work?
Once the Power button of FIR sauna is activated, the high-tech
ACF (Activated Carbon Fibre technology) super conductive heating
panels/wires/elements begin emitting FIR at the speed of light,
penetrating human body 3.5 to 5 cm (1.5 to 2 inches) deep
under skin, muscles and bones. Neither oxygen nor nitrogen
molecules in the air can block the FIR wave. FIR sauna works
on the ‘conversion’ principal of warming the body
on coming in direct contact, without warming the air between
the source and the human body. In technical terms, this is
called direct light conversion. Less than 20% of the FIR heats
the air, leaving 80% available to be directly converted to
heat within the body. FIR makes us feel comfortably warm as
we perspire profusely, yet our skin and tissues are not hurt
by the heat wave.

|The human body responds to this deep heating
effect via a hypothalamic-induced increase in both heart volume
and rate. The body tissues selectively absorb FIR as the water
in the cell reacts in a process called ‘resonant absorption’.
This is said to occur when the frequency of FIR matches the
frequency of the water in the cell causing toxins to be dropped
off into the blood stream and excreted by way of sweat, faeces
and urine. If there are tissues under healing or repair, the
boost of infrared ensures fullest healing response.
Resonance and vibration loosens unwanted fat and toxins,
which further decompose into water, CO2, inorganic salts etc.
and then excreted along with sweat from the expanded pores
in the skin. Due to deep penetrating qualities of FIR, up
to 1.5 in. 2 in. (45mm - 50mm) deep into body’s tissues,
there is a heating effect deep in the muscular tissues and
internal organs. This deep heating is responsible for healing
effect and other health benefits associated with FIR
Infrared Heat safe?
|According to NASA infrared ‘passive
exercise’ was the ideal way to keep astronauts fit during
space flight. In hospitals baby care units, incubators are often
equipped with infrared heating systems to keep new born babies
warm. World over Far Infrared Rays are being used to promote
growth in plants, purify polluted air, treat injured athletes,
for cooking and even encourage new hair growth. FIR sauna is
not only safe, but has multiple benefits revolutionising the
way we keep fit.
Far Infrared is a natural form of light energy that is safest
of the rays. It should not be confused with harmful ultraviolet
radiation. Unlike UV rays, FIR will not sunburn or damage
the skin or tissues below it. According to the 9th edition
of Clayton’s Electrotherapy, “infrared is the
only antidote to excessive ultraviolet radiation”. FIR
heat / energy are also capable of neutralizing the negative
effects of toxic electromagnetic frequencies (EMF’s).
In fact, FIR is a normal heat that is absolutely essential
for all living things to remain tranquil, calm and healthy.

are the benefits of Far Infrared Sauna?
| Far Infrared benefits are immediate and
amazing! Regular sports take time and always carry the risk
of injury. While active exercise and balanced diet are excellent
for good health, an equally good substitute – the amazing
new Far Infrared Sauna – lets you stay healthy in pleasant
and relaxing way. Soft, soothing Far Infrared heat helps receive
the all round ‘training effect’ (30 minute FIR sauna
= 10km run) while reading, watching TV, talking on phone, listening
to your favourite music or simply relaxing in the comfort of
Increased Blood Circulation
| Infrared sauna is thought to be seven
times more effective at detoxifying heavy metals as opposed
to conventional heat or steam saunas. Modern diseases are result
environmental pollutants. Studies have confirmed that diet and
environmental chemicals cause 95% of cancers. They are absorbed
into our body through food containing additives, antiseptics,
agriculture chemicals etc. The United States Food and Drug Administration
(FDA) have found that sweating is one of the most effective
ways to expel these chemical and heavy metal toxins from our
body. ‘Incurable’ chronic diseases that were thought
to have no known cause often disappear once toxin chemicals
are gone. Since our FIR sauna is the safest, most efficacious
and economical way of depurating stored toxins; this makes it
a household necessity.
Our body reacts to the increased FIR heating through the
natural cooling process of perspiring. Increased blood
circulation stimulates the sweat glands, releasing built-up
toxins and waste. Through the perspiration process, acid and
waste residue like toxins, sodium, alcohol, nicotine, cholesterol,
urea and the potentially carcinogenic heavy metals (mercury,
zinc, lead, nickel, cadmium) are removed from the cells.
Lowers Blood Pressure
|Extensive research by NASA in the early
1980s concluded that infrared stimulation of cardiovascular
function would be the ideal way to maintain cardiovascular conditioning
in American astronauts during long space flights.
The body responds to the deep heating effect of the FIR via
a hypothalamic-induced increase in both heart volume and rate.
As body increases sweat production to cool itself, the heart
works harder pumping blood at a greater rate to boost circulation,
supplying the conditioning benefits of a continuous exercise.
Heart rate, cardiac output and metabolic rate increases, while
diastolic blood pressure drops, for improved overall cardiovascular
fitness. The lower FIR temperature ranges are found to be
very safe for those with cardiovascular risk. This conditioning
has even greater benefit to those who are unable to exercise.
Thus, our FIR saunas will provide overall, systematic treatment
of muscles, joints, and body especially for areas often not
regularly addressed through movement and exercising.
‘Passive exercise’ of FIR Saunas results in significant
lowering of blood pressure, cholesterol and triglycerides
“Regular use of a sauna…may be as effective as
a means of cardiovascular conditioning and burning and burning
of calories as regular exercise.” Journal of the American
Medical Association 8/7/1981
|Burn Calories & Weight Control
Improved Muscle Tone and Strength
Increased Energy levels
Although weight loss from perspiration
is quickly regained by re-hydration with water, the FIR effect
of sending more blood to the capillaries and converting fats
results more than 600 calories burnt in just one 30 minute
session – the equivalent of running 10-15 km. As our
body expends energy to produce sweat (1gm. sweat requires
0.586 kcal), a moderately conditioned person can easily sweat
off up to 1000 gm or more in a FIR sauna session.
Further, when heavy metals are reduced, the metabolic imbalances
that were causing poor digestion and weight gain will be corrected.
Also, lipophilic toxins stored in fat are decreased making
it easier for weight loss.
Because fat becomes water soluble at 110ºF, subcutaneous
fat can be released along with the sweat and toxins. The FIR
sauna is especially valuable system for those who don’t
exercise and those who cannot exercise yet want an effective
weight control and fitness program, giving them the benefits
that regular exercise brings.
With Infrared Therapy, result is immediate. The infrared
Sauna-in-spa® will carve out a younger, taut and shapely,
fit body with a boost of energy level at a new high.

|production of white blood cells by the
bone marrow and killer T cells by the thymus. The overall result
is immune system enhancement.
| Immune System Enhancement
|A typical FIR sauna session will
cause a brief 1 to 3ºF increase in body temperature.
As the body works to combat this ‘artificial fever’
the body’s immune system is strengthened. This helps
in body’s defence against bacteria, microbes and
consequent infection. This phenomenon also helps trigger
the production of white blood cells by the bone marrow
and killer T cells by the thymus. The overall result is
immune system enhancement.
Stress and Fatigue Reduction
The most immediate relief offered by the FIR sauna is simple
relaxation, as it melts away the stress and tension of urban
life. Dilated capillaries lead to improved blood circulation
resulting in reduced stress levels. Just a few minutes in the
gentle warmth of FIR sauna will give you an overall massaging
effect, soothing jangled nerves and knotted muscles. The user
will feel rejuvenated and renewed, restored in both body and
| Clears Cellulite
| Cellulites are gel like lumps made up
of fat, water and wastes trapped in pockets beneath the skin.
An infrared thermal system warms three times deeply as conventional
saunas, causing heavy sweating leading to effective clearing
of this kind of unwanted debris from the body.
| Relieves Muscle Spasm, Body Pain, Joint
Pain and Stiffness
| Treats Rheumatoid Arthritis
Deep heating effect of the FIR sauna helps peripheral blood
vessels dilate, bringing relief and healing to muscle and soft
tissue injuries. Increased blood circulation carries off metabolic
waste products and delivers oxygen-rich blood to oxygen depleted
muscles, enabling them to recover faster. Muscles relax most
readily when tissues are warm, for greater flexibility and range
FIR heat can easily help ease patients suffering from arthritis,
sprains, neuralgia, bursitis, muscle spasm, lower back pain,
joint stiffness and several other muscular-skeletal ailments.
Much of the stiffness aches and soreness that comes with aging
is reduced or eliminated.
| Skin Cleansing
The increased heating causes pores of the skin to open up. The
profuse sweating achieved within few minutes in an FIR sauna
sweats off deeply imbedded impurities (dirt, oil and makeup)
and dead skin cells, leaving the skin glowing, immaculately
clean and free of body odour.
Increased blood circulation draws the skin’s own natural
nutrients to the surface. Your skin will experience firmness,
improved tone, elasticity, texture and colour.
Roughness will start declining making way for smooth and
Increased blood circulation has also been shown to relieve
acne, eczema, psoriasis, burns, lesions and cuts. Further,
open wounds heal more quickly, reducing scarring.
| Athletic Performance
| Now athletes and sportsmen can forget
tedious warm-up exercises. They will be able to ready their
muscles using our FIR sauna better than standard warm-up exercise.
Since pre-competition warm-ups can end up tiring an athlete,
our saunas ‘deep thermal therapy’ will offer an
exertion-free alternative. The idea of "passive" warm-up
before competition is not new. Hot pads and steamy showers are
other ways of warming the muscles and improving range of motion
in the joints. However, the effectiveness of our FIR sauna is
FIR heat therapy can also be used in both the prevention
and rehabilitation of overuse injuries and to combat the after-effects
of torn muscles and tendons. It can be valuable during warm-up
before training sessions and competitions and in cold weather,
increasing, as it does, the mobility of joints.
Injuries caused by trauma or overuse, such as ligament injuries
and muscle ruptures, are often treated during the acute stage
by cooling and bandaging so that the bleeding in the injured
area is limited. After the initial 48 hours, FIR heat therapy
can be introduced to help the healing process, which, once
the risk of haemorrhage is over, is aided by increased blood
| Control Diabetes
FIR Therapy can control diabetes. Diabetes is a disease that
prevents our body to balance the use of glucose (energy) derived
from the food we eat. Common symptoms of Diabetics are: Frequent
urination, excessive thirst and hunger, nausea, weakness and
fatigue. FIR rays can increase blood circulation to rejuvenate
healthy cellular functioning. Cells get a chance to flush out
toxins and wastes and replace them with fresh oxygen and nutrients
from the blood stream. New research has also shows FIR can inhibit
bacterial growth, thus reducing chance of infection which most
diabetics are prone to. Overall, FIR saunas help in lowering
blood sugar levels.
| Bed-Ridden or Wheel Chair Bound Users
|FIR saunas make it possible for people
in wheel chairs, or those who are otherwise unable to exert
themselves, or those who won’t follow an exercising and
conditioning program to help improve blood circulation. Our
FIR saunas definitely allow more variety in any ongoing training

of Infrared Sauna
Palm healing, which is a 3000 years old tradition in China,
has been based on the healing properties of the natural infrared
rays. Chinese researchers consider the band from 2 to 25 microns
as the most therapeutic.
Sauna use has been popularised by Finns whose old religion
used it as a ceremony for the mental, spiritual and physical
cleansing. This science was brought by Finns who migrated
to Finland between 5000 and 3000 BC, from an area north west
of present day Tibet.
Numerous saunas appear along the Mediterranean towns cities.
The first known Sauna Bath appears in the palace of King Minos
of Crete in 1700 BC.
Sauna benefits of Far Infrared therapy first began with Socrates
providing an answer for depression using light.
While Native Americans developed saunas as sweat lodges,
the German physicians have been using whole body infrared
therapy for over 80 years.
Dr. Tadashi Ishikowa received a patent on the zirconia infrared
heaters in 1965. They were mostly used exclusively by medical
practitioners in Japan until they were released for public
use in 1979.
The infrared idea has been further refined and sold in the
United States since 1981.
