half hour, and gradually increase the length and intensity for several
minutes and/or degrees every other day. Remember to drink a lot
of water, fresh juices, or herbal teas. Replenish minerals to avoid
becoming drained or dehydrated. When you start it is important to
avoid overuse, and low temperature burns and get the rst benets in
a safe manner without the risks of side eects from a “healing crisis”.
14. Most important is to listen to your body as you move forward –
“LOW and SLOW”. It is easy to overdo if you move ahead too quickly,
and the cumulative eects are much more desirable without the
lightheadedness or other side eects that can come with rapid
detoxication. The maximum time for each heat level is not specied.
It depends on the mat’s size, temperature level, and one’s age, health,
body size and composition, and many other factors. Basically, the
main rule is to start with low settings and gradually increase
the intensity, length and frequency of sessions. Of course if you
are an experienced FIR sauna user, you can start with the maximum
temperature level, or you can even use the sandwiched-between-
two-mats session, but we always recommend checking with your
doctor rst and using common sense to avoid overuse.
15. As soon as you are sure that your body reacts ne, you can use
your mat as long as you like. Unless you have special needs,
you can use it from a few times a week for 30 minutes to 12
hours daily and it should be an enjoyable process. If you want
an intensive sweating sauna-like detox, choose the maximum
temperature suitable for your health and cover your body with a
blanket or another mat. If you just want comfort, set the medium
heat levels at around 112–122 °F (45-50 °C). If you are just
starting out 20 minutes may be enough. Dierent people react
dierently and enjoy dierent modes. Some folks with weakness
caused by hypothermia use FIR mats all the time on slightly warm
temperature to revive and feel well again. Other people use
amethyst heating mats from one hour on high temperature to 12
hours on warm temperature. Be sure that sessions are comfortable
for you and bring about a better feeling and more energy, and of
course remember to get approval from a health professional.
16. If you accelerate this way, the rst aim is to create a feeling of
relaxation. To relax, you may have a short session before
bedtime of about half an hour, starting at 40-50 °C, and then
decreasing to the lowest levels of 30-40 °C. If these levels cause
any lightheaded feeling or overstimulation, the temperature should
be set even lower or even the mat should be used in unpowered
mode. Especially in the summer, when it can absorb some excess
heat from your body and naturally return it in the form of radiant
FIR rays screen with a towel folded many times and covered with
several layers of standard aluminum foil. It helps for short sessions.*
6. Children may use the mat with caution and under supervision
of adults, preferably on low heat or negative ions mode only.
Consult with the child’s pediatrician before using the FIR mat and
use common sense. Do not leave children or toddlers on the mat
without supervision. They can walk, play or jump on the mat and
damage inner sensors. Children can disconnect cables from the
mat and put them into their mouths and get shocked. Take extra
care if your child has access to the room where the mat or any
other electrical device is located.*
7. If you use medicines applied by skin patches, you should
denitely consult your doctor. The absorption rate of a
transdermal medication can change. If you use an adhesive, it
may also unglue from your skin due to sweating.*
8. Cats and dogs love amethyst and gemstone mats. They feel
some energies better than humans. We suggest to have an
additional waterproof cover for the mat to protect it from
any liquid and make sure your pet will not chew or scratch
the cable, controller or pad. We recommend non-powered,
non-electric amethyst or gemstone mats for pets. Consult
with a veterinarian prior to use mat for heating. Be careful
with pets sleeping on the device. It should always be turned o
without supervision.*
9. You should always drink A LOT before the session, during the
session and aer the session – if you feel dry mouth it means
that there is not enough water in the body. And it should not
be just water, you may need to replenish some electrolytes and
minerals as Ca, K, Mg, Na. Twitching may be a sign of these salts’
serious decit or imbalance so if you sweat a lot herbal teas, fruit
juices, and mineral water rich in K and Mg or mineral supplements
may be necessary. Proper hydration also promotes all eects
improving detoxication caused by sweating.*
10.Overusing the device on maximum temperature may result
in excessive stimulation. Use moderately on high temperature.
Even if your mat can heat in a continuous mode, it is strongly
recommended not to use the high heat settings for more than
3 hours for your safety! Some temporary symptoms of organism
detoxication (“healing crisis”) may occur especially if you start
too fast.*
11.Detoxication high heat program should not be done without
a doctor’s approval and supervision. Some drugs, chemicals,
and toxins which we take into our bodies with air or food end
up getting stored in our fat tissue. They can aect you as you
mobilize them and sweat them out. Before toxins are excreted
and exit through the sweat pores they are absorbed from your
decomposed by FIR heat fat tissues into the bloodstream. While
traveling on their way to be eliminated, substances can exert the
same eects that they do when you had originally taken them. If
a lot of residue was accumulated in your fat tissue and their
release is too fast, the buildup of these poisons can make you
feel worse. That is what is called detoxication or a “healing
crisis”. If you are chemically allergic or extra sensitive, the
dangers of infrared function, regarding the release of toxins, may
be serious. If you feel any signs of “healing crisis”, stop using the
mat and consult your doctor as the same symptoms may be also
the signs of serious illness.
12.William Rea, MD, one of the most knowledgeable doctors in the
world regarding environmental toxicity and sauna detoxication,
warns: “Uncontrolled, too-rapid mobilization can have
devastating eects on chemically sensitive patients.” Of
course it does not mean that chemically sensitive people
cannot get rid of toxins. Just that it should be done very slowly
and carefully, and with a doctor’s supervised detox program.
Slowly and gradually increasing heat level, session length,
and frequency is the best path forward and It is important
to immediately decrease intensity, duration and frequency
of sessions and contact your health professional if you feel
symptoms of a “healing crisis”.*
13.The most important thing when you start to use the mat is to
avoid acupressure overstimulation and overheating. If you would
like to sleep on your mat, do it slowly, adapting your body to
the pressure. You can start with shorter sessions at bedtime with
3-D Pad and extra cushioning layers and move forward gradually.
It is like acupuncture – there’s no need to overstimulate the body
from the outset, it is better to increase the intensity of pressure
slowly and continuously.
14.The same careful approach is appropriate to heat function. Our
skin sensors can easily detect the high temperature caused
by standard conduction heat, but our ability to feel the
eects of radiant infrared heat is limited. The FIR warmth
is much more penetrating, so the mat should be used on much
lower sensible temperature than a standard heating pad, and
it demands extra care, especially for long or all-night use.
This especially refers to the larger sized mats, which are very
powerful. Please use such mat only on the lowest setting
while sleeping.
Use common sense, self-educate, listen to your body and we hope
you experience as many positive results as we have, now that you
have your own ThermoGem™ Mat.

crystal rays to those parts of your body which need more soothing
warmth.*
17. The second target usually is to cause sweating, which is great
for detoxifying the body. All intensive high heat sessions should
be done with proper rehydration and electrolyte replenishment,
and within the rst half of the day. It may take up to an hour to
preheat the mat under a thick blanket to a high heat level. Then you
can lay on your back on a bare mat, or a mat with a thin protector
or a towel on it and cover yourself with a blanket. Aer the session,
just leave the bare mat for half hour more while still heating to dry
it out. Of course if your body does not sweat much, you may not
start to sweat from the rst session – but aer several it should
come. Drink a lot of hot herbal teas (not cold drinks) before and
during the session to accelerate sweating. When your body gets
used to sweating it will be easier to sweat voluntarily.*
18. For FIR Heating, if you lay bare on the bare mat with your
body covered with a thick blanket, you will get the maximum
“detox” eect, as no heat will be lost or dissipated. All crystal
rays will be radiated into your body. Some advanced customers
even use foil blankets reecting FIR Rays back to the body,
but it is very intensive practice and it cannot be recommended
without a doctor’s approval. Sweat releases a lot of toxins, and
FIR releases even those stored in deep fat tissue, into the blood. It
may be irritating and erosive to the surface of the mat. That is why
something like a sheet or a protector cover under your body is must-
have for everybody. Perspiration may also temporarily make you feel
worse, but when the sweat is out you should feel refreshed.*
19.Wearing clothes or using covers or sheets on the mat hinders some
of the anion eects, but it should not be an obstacle to FIR Heat.
20. If you are falling asleep while on mat, choose 30-45 °C or
86-110 °F low level of FIR Heat before going to bed.*
21. Getting a headache or feeling dizzy is a sign of “healing crisis”
(dehydration). It means that you are detoxing too fast. Lower the
temperature, drink more water and stay on the mat for shorter
time. It is important to feel comfortable and enjoy your experience,
so listen to your body and adjust intensity and duration accordingly.
22.Classic ThermoGem™ mats are designed to be used at on your
bed, massage table or sofa. Mini Mat (20x32”) can be bent up
to some degree to cover your body while heating. But the special
Chair Mat is a preferable choice for sitting practice in your chair,
recliner or on the sofa and only the exible ThermoGem™ pads
and blankets can be bent to wrap your body.
1. Extra care is necessary if you are diagnosed with diabetes. If
patient has a lot of sugar in the blood, it clots the blood vessels
and causes nerve disorders. Some people with diabetes can, over
time, develop nerve damage throughout the body. It is called
diabetic neuropathy. If you have diabetic neuropathy and loss of
sensitivity you should use a strict time/frequency/temperature
protocol established by your doctor, and only under supervision.
You should start very slowly and monitor your blood sugar.*
2. Titanium pins, rods, articial joints or any other modern surgical
implants usually reect FIR rays so they should be generally safe.
But some joint replacements and piercings with other metals may
be warmed by infrared rays. So safety precautions should be
taken if you lay with joint replacements in direct contact with
the mat. If you lay on your back and knee or hip replacements
are above the mat, there should not be a problem. But of course
if you feel any discomfort in the implants area, it would be
better to decrease the temperature and session length or to
turn the mat OFF. It is also advised that you consult your surgeon
and implant manufacturer.*
3. Silicon implants may be warmed by infrared rays, so safety
precautions should be taken if you lay with implants in direct
contact with the mat. If one has breast implants but lays face-
up, there should not be a problem. Usually silicon used in medical
implants is known to melt at over 200 °C (392 °F), so it should
not be adversely aected by infrared rays. Please, consult your
surgeon and implants manufacturer prior to use of heat directly
on implants areas.*
4. Heating of the low back or low abdomen areas of a woman’s
body during the menstrual period may temporarily increase their
menstrual discharge. Some women endure this process to gain
the pain relief commonly associated with their cycle, whereas
others simply choose to avoid using the mat during that time of
the month.*
5. It is reasonable to protect groin area, face, head and all other
areas sensitive to heat. If contraception is not your aim, and if
you lay on the mat on your belly, it is important to protect your
genitals. You can use a cooling pad or make a non-permeable for
TIPS: TROUBLESHOOTING
1. Ensure the electrical wall socket that you’ve plugged the mat
into is working correctly. Plug another device into it to ensure
it has power. If it is not working, consider checking the electrical
panel as a breaker may have popped (or broken) and needs to be
reset. Or try another electrical wall socket that you have veried is
powering other devices. If you are using a surge protector, ensure
it is working properly. Plug another electrical device into and
verify that it is working.
2. Ensure the controller’s mat plug is pushed all the way in to
the mat’s receptacle socket so that it is snug tight with no
space at all between the plug and the mat’s socket. A loose
connection can cause loss of signal exchange between the
mat and the controller, and when too many errors accumulate
the controller’s calibration may fail. Controller will show error
messages or the mat will not heat up properly.
3. Make sure that the power button on the controller has been
turned ON. The controller may show OFF on display. It means
that either preset heating time is over or the connection between
controller and mat is lost. Try adding time, powering the controller
ON/OFF, or reconnecting it.
4. Please activate the timer button and choose one of the timer
settings for the mat to start heating. Some models of the
