About Infrared

What is Infrared Radiant Heat?

Sunlight is a combination of visible light and invisible light. The seven colors of the rainbow are visible lights, and infrared rays and ultraviolet rays are invisible lights. Infrared rays are one of the sun’s rays. They are the healthiest; they penetrate deeply into your skin and dissolve harmful substances accumulated in your body. Infrared rays also vitalize your cells and metabolism.

Far Infrared

Far infrared waves penetrate into our body to activate the sweat glands. The sweat glands offer one of only a few mechanisms that the body has to eliminate toxins and since the skin is the largest organ in the human body it is apparently a very good means for elimination.

When far infrared waves are applied to water molecules (comprising 70% of our body) these molecules begin to vibrate. This vibration reduces the ion bonds and the eventual breakdown of the water molecules causes encapsulated gasses and other toxic materials to be released.

Bring the benefits of an infrared sauna into your home with a new Jacuzzi® infrared sauna.

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, aide in wound healing by bringing more blood to the effected area, help reduce inflammation and much more. We estimate 10-15% additional benefit from a full spectrum sauna.

Why Infrared Technology?

Tests have shown that the energy output of our True Wave™ far infrared heaters is so closely tuned to the body’s own radiant energy, that our bodies absorb as much as 93% of the far infrared waves that reach our skin.

By comparison, conventional saunas must rely only on indirect means of heat: first, on convection (air currents) and then, conduction (direct contact of hot air with the skin) to produce its heating effect. Your Clearlight Infrared Sauna is best used at temperatures between 100° to 125°F versus 180° to 220°F for traditional hot-air saunas.

Is infrared heat safe?

Yes! Infrared heat is all around us. The photo above shows everything emits and receives infrared heat. This image was taken with a camera that takes a regular photograph and an infrared image of the subjects at the exact same time.

The human body emits and receives infrared heat in the far infrared band. Other surfaces, like a warm street or heated vending cart, give off infrared in the middle and near infrared band.

Do you want to experience far infrared heat right now? Take you hands and put your palms together. Move your hands about 1/2 an inch apart. You will feel warmth emanating from your palms. This is far infrared heat is very similar to the infrared heat emitted from our True Wave™ heaters. Radiant far infrared is all around us and is essential for human life.

Why is infrared heat better than traditional sauna?

Jacuzzi® infrared saunas use low-EMF True Wave™ Carbon/Ceramic heaters that produce invisible, far infrared heat. This is the same type of heat as produced by the sun and our bodies. Infrared heat is very safe and not at all like the heat produced by microwaves. In an infrared sauna, only 20% of the energy is used to heat the air, leaving the rest of the energy to heat the body. The radiant heat can penetrate deeply below the skin, producing a gentle warming inside the body. The temperature inside an infrared sauna is adjustable and averages a comfortable 100°F to 130 °F. These lower temperatures allow you to sweat faster and to tolerate a longer sauna session, offering greater therapeutic benefit. Typical sessions last 20 to 45 minutes and can be repeated once or twice during the day to maximize the benefits. Infrared saunas leave you feeling invigorated, not depleted like conventional saunas.

Infrared heaters warm the body in the same manner as natural sunlight. Infrared heat therapy uses the wavelengths of the visible and non-visible light spectrum of sunlight that heat the body. Traditional saunas raise the temperature of the air, to a very high level, to warm the body. Some people have difficulty breathing in this extremely warm air. Infrared saunas work differently. Instead of heating the air within the enclosure, infrared saunas directly heat the body directly. The result is deeper tissue penetration. In an infrared sauna, the body perspires and receives all of the healthy benefits but avoids the harmful and extremely hot air of a traditional sauna.

Infrared Sauna Facts

Infrared saunas are increasingly popular in the health and wellness community for a number of reasons, including the numerous health benefits, and they just make you feel good! What exactly is an infrared sauna? Before we dive into what infrared saunas are, we should first understand infrared wavelengths.

Infrared Wavelengths

The sun produces a combination of visible and non-visible light, and one of those on the non-visible spectrum is infrared rays. Invisible infrared wavelengths are what makes the sun feel warm (and ultraviolet wavelengths are what make the sun bright). Scientists have established that infrared waves are beneficial to the human body because they are easily absorbed--stimulating the lymphatic, immune and cardiovascular systems--and help remove toxins. Infrared does all of this without any of the harmful rays of sunlight.

There are three main categories of the infrared spectrum: near infrared, mid infrared, and far infrared.

Near Infrared – Near infrared has the shortest wavelength and is absorbed just below the surface of the skin. This spectrum will help raise your core body temperature and assist with skin purification and rejuvenation, providing anti-aging benefits.

Mid Infrared – This is a longer infrared wavelength that penetrates deeper into the body’s soft tissue. Mid infrared waves help increase circulation and release oxygen to injured areas.

Far Infrared – Far infrared is the longest infrared wavelength and penetrates deep into your body. Far infrared wavelengths result in the greatest levels of detoxification. They also increase your metabolism aiding in cardiovascular health, improve circulation through vasodilation, relax muscles, reduce joint pain and much more.

What is an Infrared Sauna?

While we call our Clearlight Infrared models “Saunas,” they are really infrared therapy cabins. It just so happens that the sauna environment is a great environment to deliver infrared as you are not wearing any clothing and you are surrounded by the infrared heat. The black panels you see inside the sauna are our True Wave® far infrared heaters. In our Sanctuary sauna models, the silver front heaters are our True Wave full spectrum heaters offering near, mid and far infrared.

Rather than use steam or the traditional “box of hot rocks” heating elements, the infrared sauna heaters use the infrared spectrums listed above to promote relaxation amidst various other health benefits. In an infrared sauna, the air temperature is less important than the quality of the infrared heat. Just warm up your Jacuzzi® infrared sauna for about 15 minutes and get in. You will warm up with the sauna. As your body absorbs the infrared heat, this will increase your core body temperature inducing a deep and relaxing sweat. Using your infrared sauna at lower temperatures means you can stay in longer and reap more benefits.

Infrared Saunas Versus Traditional Saunas

The main difference between infrared saunas and traditional saunas is how they use heat. Traditional saunas use a single heater which heats the air and in turn, this hot air heats the user. In contrast, infrared saunas use advanced therapy to heat the user directly with only a small percentage of the heat heating the air. This results in a deeper sweat at a lower ambient air temperature. In fact, infrared saunas usually operate between 115° – 135°F, while traditional saunas can get up to 195°F.

You will get all of the relaxation benefits of a traditional sauna along with the increased health benefits that infrared offers, all at a much more comfortable temperature. Infrared saunas are also dry saunas and many users find this makes for a more comfortable sauna session.

Not only are infrared saunas extremely beneficial, but they are also more efficient and require less electricity (according to Livestrong.com, a traditional sauna is almost three times as expensive to run as an infrared sauna). This also means that the warm-up time of an infrared sauna is much quicker than a traditional sauna.

Our Sanctuary Full Spectrum Saunas offer near, mid, and far infrared technologies. Our Premier Far Infrared Saunas offer all of the benefits of far infrared heat. Surround Yourself In Wellness in a Jacuzzi® infrared sauna.
