Red light therapy and infrared therapy are often mentioned together in the world of wellness, huidverzorging, and pain relief — and for good reason. They both use light energy to stimulate healing and regeneration in the body. But are they the same thing?
Laten we het opsplitsen.
Wat is roodlichttherapie?
Roodlichttherapie (RLT) gebruikt zichtbare golflengten van rood licht, typisch tussen 620nm en 660 nm. These wavelengths penetrate the skin to a shallow depth — around 8 naar 10 millimeters — and are known to:
- Stimuleren productie van collageen
- Verbeteren skin tone and texture
- Promote wondgenezing
- Reduce inflammation on the skin’s surface
- Aid in haargroei
Because red light is visible to the human eye, RLT often gives off a soft, warm red glow.
What Is Infrared Therapy?
Infrared therapy uses invisible light, specifically nabij-infrarood (NIR) golflengten, typisch tussen 700nm and 1100nm. These wavelengths penetrate much deeper into the body — up to 5 centimeters (over 2 inch) — reaching spieren, gewrichten, en zelfs botten.
Infrared therapy is commonly used to:
- Relieve joint and muscle pain
- Enhance circulation and oxygenation
- Reduce deep inflammation
- Steun nerve regeneration and repair
- Verbeteren recovery after workouts or injury
Since NIR light is onzichtbaar, these devices won’t appear to glow as brightly as red light therapy panels, though they may still emit some warmth.
Key Differences Between Red and Infrared Therapy
| Functie | Roodlichttherapie | Infrarood therapie |
|---|---|---|
| Golflengte | 620–660 nm | 700–1100 nm |
| Zichtbaarheid | Zichtbaar (red glow) | Invisible |
| Penetratiediepte | ~10 mm (skin level) | Tot 50 mm (spier, joint, bone) |
| Primary Uses | Gezondheid van de huid, anti-veroudering, haargroei | Pijnverlichting, herstel van de spieren, deep tissue healing |
| Sensation | Warm, glowing | Often no visible light, deeper warmth |
Can They Be Used Together?
Yes — and they often are.
Many modern red light therapy devices combine rode en nabij-infrarode golflengten for maximum therapeutic benefit. This dual-wavelength approach allows the treatment of both oppervlakte-niveau En deep tissue issues in one session.
Bijvoorbeeld:
- 660nm rood licht can boost collagen for skin rejuvenation
- 850nm nabij-infraroodlicht can reduce joint pain and inflammation deeper in the body
This combination is especially popular in full-body therapy beds and panels.
Laatste gedachten
Red light therapy and infrared therapy are not exactly the same — but they’re closely related and often work best together. Red light targets surface skin concerns, while infrared goes deeper to relieve pain and support recovery. Whether you’re aiming for younger-looking skin or relief from sore muscles, understanding the difference helps you choose the right device — or combination — for your wellness goals.
