Red light therapy (also known as photobiomodulation) has moved from the world of sport and physiotherapy practices into the living room. But what does it actually do?
The principle
Red light (±660 nm) and infrared light (±850 nm) penetrate a few centimetres into skin and muscle tissue. There, they stimulate the mitochondria — the energy factories of your cells — kickstarting recovery processes.
What is it used for?
- Muscle recovery: athletes use it before and after training against muscle soreness
- Skin: red light is used for a more even, fresher-looking complexion
- Joints and back: the warmth and increased blood flow can ease stiffness
Important to know: research is promising but still very much developing. Think of it as support, not a replacement for medical treatment.
Using it at home
Place a red light therapy belt for 10–20 minutes a day on the area that needs attention — lower back, abdomen or shoulder. Consistency matters more than long sessions: short daily use gives the best results.
