What is a Stonebed?

Jangsoo Stonebed is a functional bed, considering a user's health first by eliminating the factors causing adult diseases such as blood circulation problem. The excellent quality of Jangsoo Stonebed is that its temperature can be freely regulated, thanks to an internal heating appliance. Hence, the users can enjoy a warm bed, plus a sauna effect and hyperthermia. The far-infrared rays are emitted from the natural stone. Ceramics and jade placed on the top of the stonebed can give a good effect on a user's blood circulation.

V.L.F.(Very Low Frequency) System
In case of the Type A and Type D of JANGSOO stone bed, the mats are designed to use the very low frequency system which is begin adopted for medical equipment. (Those who use a cardiac pacemaker of pregnant women are not allowed to use the V.L.F. system) The magnetic wave of very low frequency arises from the exchange of "N" and "S" magnetic pole in a speed of 50~60 turns per second. This is same as Natural wave such as solar radio-frequency radiation and terrestrial magnetism wave, so it can pass through anything and change periodically. It is the longest magnetic field in the universe. This is to activate the ion-pathway of cells and to invigorate the blood circulation and metabolism, and also giving a excellent effects on a pain-relief and antiphlogistic. We recommend that the very low frequency system should be used for 30 or 60 minutes.

Negative(-) Ion
In the mat of JANGSOO stone bed, the bio wave(Negative Ion emitting rate : 226ion/cc) and the carbon film(for Type A, 151ion/cc) themselves emit negative ion.
Modern homes and offices seal out negative ions. Computer terminals, fluorescent lighting, forced air ventilation systems, and modern building materials generate an over abundance of positive ions. Positive ions make us feel tired, depressed and irritable.
Balancing the ionization in your home may help to combat the Ill feelings associated with our stressful lifestyles. The worlds most tranquil and refreshing regions are loaded with billions of negative ions. Air near waterfalls, mountains, beaches and forests are among those places where ionization levels are in complete and natural balance. After a lighting storm, most of us feel invigorated and refreshed. This is because the electrical storm has generated trillions of gloriously tranquilizing negative ions that ease tension and leave us full of energy. Scientific studies have shown that atmospheres charged with negative ions relieve hay-fever and asthma symptoms, seasonal depression, fatigue and headaches. It's also been shown that negatively ionized atmosphere improve performance of voluntary movement, increase work capacity, sharpen mental functioning, and reduce error rates.

Effects of Negative Ion

1. Blood purification
2. Revitalization of Cells
3. Increase in Resistance Power
4. Controlling of Autonomic Nerves

Far Infrared Ray

The carbon film(Type) and far infrared ray spinning silicon(Type D) emit far infrared ray.
F.I.R.(Far Infrared Ray) is a form electromagnetic light energy from the sun. It falls within the same family of the Infrared Ray in the light spectrum, but due to its longer wavelengths, FIR cannot be seen by human eyes, just like ultraviolet rays and X-ray. This energy is absolutely essential for all living things, including human beings, in the world. FIR, by its physical properties, has a deep penetrating power. It can penetrate through the skin into the subcutaneous tissues thereby improve blood circulation, promote overall metabolism, get rid of bodily toxins and metabolic by products from the body and improve cellular vitality. Upon penetrating the skin, FIR transforms from light energy into heat energy. The thermal effect within the deep layers of the tissues causes blood vessels and capillaries to dilate, promoting a better blood circulation.

Six Main actions of FIR

1. Thermal action : Maintain body in normal temperature.
2. Maturing action : Promoting human body's maturing.
3. The self-cleaning(self-purification) action : Keeping the balance of sufficient nutrition in your body.
4. Dryness and moisture action : maintaining your body in normal moisture.
5. Neutralization action : Promoting eliminating waste matter and deodorizing in your body.
6. Resonance action : Promoting metabolism and enhancing various physiological functions of human body resolving lots of nutriment.

ETC.
There were some people who had a prejudice against stone beds. They thought the stone bed would be hard, but now, they say they did not feel hard on their back after they experience stone bed. JANGSOO stone bed protects waist from being bent and fixes it not to be overstrained. It is good for fixing the backbones for spinal patients, the elderly with bent spine, growing teenagers, and examinees studying with their spines bent.
As dust mite can not inhabit, it provides a good environment for allergic patients.
