THE HEAT THAT HEALS
Cultures from around the world have recognized the healing power of heat for millenia. Scientists are now probing into this universal understanding to reveal its deeper truths, and to gather the data that can be used to generate new therapies and procedures to fight disease, ease pain and actually help athletes, first responders, the military, and any others who have to perform at their peak whenever called to do exactly that. Heat works, but the right kind of heat works even better.
EFFECTIVENESS OF CLEARLIGHT SAUNAS
When you are sitting in a traditional sauna, you are sitting in a hot room; 180-220 degrees. In your Clearlight Infrared Sauna only about 20% of the heat goes to heat the air and the other 80% directly heats your body. The warming effect on your body stimulates your cardiovascular system, your immune system and your lymphatic system. Your bodies response to that is to sweat.
When you first get into your sauna you will start to perspire right away because of the room temperature. After about 10-15 minutes you will start sweating profusely as your body responds to the far infrared heat. You will actually sweat more in an infrared sauna than in a traditional rock sauna. Studies show that sweat from a traditional sauna contains about 3% toxins where sweat from your far infrared sauna contains about 17% toxins. The detoxifying and deep penetrating heat from a Clearlight Sauna makes them very, very effective.
Your skin doesn’t just keep your organs in
A lot of people forget that the human skin is not just an outer envelope of the body, it’s actually your body’s largest organ. It provides a wide variety of functions, and runs a lot deeper than you may think. And this is where an understanding of infrared light, and how it works, comes in.
As you can see in this graph, only one form of light energy penetrates fully throughout the several layers that make up the skin (IR-A), while its sibling forms (IR-B, IR-C) are able to penetrate to a certain depth. This ‘deep penetration’ capability is what makes it so powerful. A far infrared sauna uses the specific part of the spectrum. These two parts, both invisible, have a very different effect on the body.
Infrared is an invisible form of light energy that is accepted by the body as heat. It is that deep, inner warmth feeling you get when standing in the sun. The reason we get warm from an infrared heater is because our skin and clothes absorb the light energy. It’s like the difference between being directly in sunlight versus sitting in the shade. You feel warm in the sun because the light energy that hits your clothes and skin keeps you warm, but when you’re in the shade, the light energy (and its heating effect) doesn’t reach you as well.
The ambient temperature in the shade might be a comfortable 80ºF, but stand too long in the sun, and your body will really feel it. It’s the infrared that delivers the heat that in turn generates sweat—and that, as you will see, makes all the difference when it comes to using heat as a means of decontaminating the body.
how an infrared heater works
Light’s visible spectrum goes from red (longer wavelength) up through violet (shorter wavelength), the colors of the rainbow. Infrared means “below red” just as ultraviolet (UV) means “above violet”.
Ultraviolet (UV) light has been associated with many health risks such as laying in the sun too much or excessive exposure in tanning salons. Infrared light is at the exact opposite end of the visible light spectrum, and is associated with many positive and healthful benefits. It is completely safe when used appropriately and healthy for all living things. One can be exposed to infrared light for hours without the risk of burning. In fact, infrared is so safe, that it is what is used in hospitals to warm infants.
The heat energy generated by an infrared sauna heater can penetrate human tissue up to 2 inches deep. This wave-length of energy is therapeutic because of its ability to be absorbed by the body, and can be used to safely raise the body’s core temperature. In most cases, your core body temperature will rise 2-3 degrees Fahrenheit (to over 102 degrees) within a 30-minute session.
For years, the healthcare industry recommended infrared heat lamps as a source of infrared therapy, but the lamps were cumbersome, dangerously hot, and difficult to maintain at a constant temperature. Today, many healthcare professionals use a new generation of infrared heaters to treat a variety of diseases throughout the world.
Infrared is the longest wavelength of light energy, and can penetrate deep into the body to activate sweat glands. Since sweat is one of the few mechanisms the body has to get rid of toxins, and the skin is the largest organ in the human body, use of infrared energy is a very effective means for the decontamination of the body.
When far infrared waves are applied to water molecules (which make up to 70% of our bodies), the molecules begin to vibrate. This vibration weakens ionic bonds, and the eventual breakdown of the water molecules causes encapsulated gasses and other toxic materials to be released. Far infrared energy can also penetrate fat cells causing vasodilation. As fat cells vibrate, they expel toxins, resulting in greater levels of decontamination, while causing significant metabolic stimulation that can aid in weight loss.
Full Spectrum Infrared
Full spectrum refers to the entire infrared spectrum: near infrared, mid infrared and far infrared. With the addition of near and mid infrared, you will get the maximum benefit from your Jacuzzi® sauna.
Near Infrared is the shortest wavelength, and will be absorbed just below the surface of the skin creating a sweat that promotes healing and revitalization.
Mid infrared is a longer wavelength that can penetrate deeper into the body’s soft tissue increasing circulation, releasing oxygen to reach injured areas.
Far infrared is the longest wavelength which penetrates the fat cells causing vasodilation, where the fat cells vibrate to expel toxins, resulting in the greatest levels of detoxification and stimulate your metabolism to aid in weight-loss.
The sun is the primary source of radiant energy, but not all of this energy is beneficial. Although life needs energy from the sun, too much sunlight damages the skin. Infrared heat provides all the healthy benefits of natural sunlight without any of the dangerous effects of solar radiation.
For years, the healthcare industry recommended infrared heat lamps as a source of infrared therapy but the lamps were cumbersome, extremely hot and difficult to maintain at a constant temperature. Today, many healthcare professionals use infrared heaters to treat a variety of diseases throughout the world. Jacuzzi® infrared saunas use our state of the art True Wave™ heaters.
The efficacy of infrared waves is very broad and the subject of recent study by NASA. Among the infrared waves, the far infrared rays, which have a wavelength of 6-12 microns, are especially good for the human body. These waves have the potential to penetrate 1.5 to 2 inches or more into the body allowing for deep heat and raise your core body temperature from deep inside. The deep heat of far infrared is why scholars believe that the Ondol (traditional warm floor of Korea) is good for health because the materials for the Ondol are stone and earth, both of which radiate far infrared waves when heated.
The far infrared rays consist of similar wavelengths as those emitted naturally by the human body. This is one potential explanation of why many feel energetically rejuvenated and balanced from contact with far infrared waves. It is also believed that far infrared waves help improve blood circulation and recovery from fatigue.
Near and mid infrared range from 0.75 – 5.5 microns and enhance the benefits of far infrared. With the deeper penetration, full spectrum infrared will raise your core body temperature faster, aides in wound healing by bringing more blood to the effected area, helps reduce inflammation and much more. We estimate 10-15% additional benefit from a full spectrum sauna.
Why is Infrared Heat Better Than Traditional Sauna?
A sauna is a sauna, right? Wrong. The short story is that infrared heaters warm the body in the same manner as natural sunlight (as described above). Traditional saunas work differently, raising the temperature and humidity of the air in the cabin to a very high level to warm the body.
This heavy, humid, hard to breath, and extremely warm air (180-225ºF) can be an uncomfortable experience. It could even pose a variety of potential health risks for some. Infrared saunas work on an entirely different principle.
Instead of heating the air within the enclosure, infrared saunas heat the body directly, creating a dry air environment within the cabin. The result is deeper tissue penetration. In an infrared sauna, the body perspires deeply, receiving all of the healthy benefits, but avoiding the potentially harmful, extremely hot, uncomfortably humid air of a traditional steam sauna.
Is Infrared Heat Safe?
Yes! Infrared heat is all around us, all the time.
Everything exposed to sunlight receives and emits infrared heat. This comparison image shows a scene of window washers in the visible spectrum (right) and the infrared spectrum (inset, upper left). The much cooler building elements (panels, windows, etc.) are shown in green to blue spectrum, but the three workers are clearly shown emitting infrared energy (in the yellow to red).
Human bodies both absorb and emit infrared heat naturally. To understand and experience infrared heat, take your hands and put your palms together. Now, move your hands about a half an inch apart. Feel that gentle, radiant heat between your palms? That’s infrared heat generated by your body, and very similar to the far infrared heat that is generated by an infrared sauna heater.
