Infrared and red light technology – such as panels, mats, sleeping bags, face masks, caps, and more – has become extremely popular. Everyone "wants it," but most people know little about the technology and often end up making poor choices.
Uno Vita AS and our Clinic for Integrated Medicine are pioneers in the industry. We were the first in Norway with full-spectrum infrared saunas (Sunlighten), grounding products (Earthing), advanced red light therapy systems, and we developed Luci Phi – pulsed light therapy, which is now being implemented in our most advanced panels. We also offer frequency therapy, PEMF (pulsed electromagnetic fields), and professional light therapy for clinics and home use. We have more than 15 years of experience with electromedical technologies and are now sharing this knowledge with you.
Founder Jan Fredrik Poleszynski has in-depth expertise in light, electricity, magnetic fields, and health, and is an international lecturer in electromagnetism and integrated medicine. You can watch his lecture "Let There Be Light" on YouTube (Germany, 2018, 700 participants from 26 countries) – free and in English.
🚗 Infrared sauna – as imprecise as saying "car"
When you buy a car, you know there are major differences in function, quality, safety, and lifespan. A small Skoda and a Rolls-Royce are both cars, but they represent completely different values. The same applies to saunas. Many consumers are misled because they do not understand the technology behind the term "infrared."
💸 Cheap is cheap – and cheap does not mean good
The market is flooded with inexpensive "infrared" saunas and red light devices on social media. For the inexperienced, it is difficult to distinguish quality from advertising. This article explains the difference between cheap far-infrared saunas and professional Sunlighten full-spectrum saunas – and why the effect in the body cannot be compared.
❓ Infrared that is not infrared?
Yes, it sounds strange – but the headline is meant to attract attention.
Most cheap infrared saunas emit only far-infrared light (FIR), that is, pure heat radiation, in the range of 5,000–25,000 nanometers (nm). A regular sauna actually emits similar radiation (3,000–20,000 nm), but also heats the air. Far-infrared provides more direct heat to the body, but covers only one part of the infrared spectrum.
💡 What exactly is infrared light?
Infrared light (IR) is invisible heat energy emitted by everything warm – from the sun and your body to a fireplace or sauna heater. It lies just beyond red light in the light spectrum, and although we cannot see it, we feel it as heat when the wavelength is long enough.
But not all infrared light is heat! There are three main types:
🔹 Near-infrared (NIR, 700–1400 nm) – Short-wavelength, acts more like light than heat. Penetrates deeply into tissue and stimulates cellular energy metabolism (ATP) without creating noticeable heat. Used in photobiomodulation (red light therapy).
🔸 Mid-infrared (MIR, 1400–3000 nm) – A transition between light and heat. Produces a mild warming sensation and contributes to improved circulation.
🔴 Far-infrared (FIR, 3000–20 000 nm) – Pure heat radiation that is absorbed by water in the skin and tissues, providing deep, comfortable warmth without heating the air as much.
📍 In short:
• NIR and MIR are primarily light energy, not heat
• FIR is pure heat energy – the kind you feel from the sun, the fireplace, and the sauna
• Everything warm emits infrared radiation, but only FIR provides noticeable heat
👉 Infrared light (NIR, MIR and FIR) is nature’s own energy radiation – vital, invisible, and the foundation of all heat in nature.
🌈 Full spectrum means the entire spectrum
Sunlighten delivers true full-spectrum infrared heat, meaning light across the entire IR range (NIR, MIR and FIR), in addition to red light and adjustable color therapy. This provides a unique combination of light and heat effects that no inexpensive FIR saunas can offer.
💎 Briefly explained: health benefits of red, near- and mid-infrared light
🔴 Red light (600–700 nm)
• Reduces inflammation and redness
• Stimulates collagen and improves skin elasticity
• Accelerates wound healing and reduces scarring
• Relieves muscle pain and increases cellular energy production
🌕 Near-infrared (NIR, 700–1400 nm)
• Penetrates deeply (5–10 cm) without a warming sensation
• Increases blood circulation and oxygen delivery
• Promotes repair of muscles, joints, and nerves
• Improves cognitive function and brain energy
• Reduces inflammation and supports the immune system
🟠 Mid-infrared (MIR, 1400–3000 nm)
• Provides gentle warmth and superficial circulation
• Supports muscle relaxation and well-being
✨ In short: Red light + NIR provide deep cellular effects, energy, and regeneration, while MIR provides circulation support and gentle warmth. You only get this in a full-spectrum sauna – not in a simple FIR sauna.
⚙️ Function, quality, lifespan, and safety – this is where Sunlighten is unique
🌞 Full-spectrum technology: Sunlighten is a world leader and the only manufacturer offering true full-spectrum heat – NIR, MIR, and FIR in one cabin. The body receives deep, balanced heat and light-based cellular activation.
🔥 SoloCarbon 3-in-1 heating elements: Patented technology that converts almost all energy into infrared heat. Provides rapid, even heating and maximum effect without loss.
🌈 Smart controls and programs: Touchscreen and app with seven preset programs (detox, cardio, pain relief, weight reduction, relaxation, recovery, skincare). Integrated chromotherapy (16 colors), Bluetooth audio, and vibration massage.
🌳 Construction materials: Solid basswood (odor-free and allergy-friendly), eucalyptus, or Canadian cedar – stable wood species with low off-gassing. The unique Magne-Seal construction provides tight joints, fewer screws, and a long lifespan.
⚡ Low EMF radiation: Radiation from the panels is lower than in ordinary household appliances – safe for daily use.
💡 Integrated Luci Phi pulsed light therapy: Combines precise light and frequency pulses to stimulate cells and mitochondria. Provides synergy with PEMF and grounding for deeper biological effects.
🧩 Easy assembly: Assembled by two people in about one hour, without special tools.
