Stiff shoulders, achy knees, that tight lower back at the end of a long day — these everyday niggles are one of the most common reasons people first try red light therapy at home. It’s gentle, drug-free and easy to build into a relaxing routine.
How it works on deeper areas
The near-infrared wavelengths (around 810–850nm) are the key here. Unlike visible red light that stays near the surface, near-infrared reaches into the deeper tissue around muscles and joints. Research into photobiomodulation suggests it may support comfort and the body’s natural repair processes in these areas — which is why it’s increasingly found alongside more traditional approaches.
Building it into your day
This is where a home panel shines. A short, warm session on the area that’s bothering you — a few times a week, at a comfortable 15–30cm — is the pattern most people fall into. Many make it part of an evening wind-down.
Choosing a panel for comfort
Because you’ll often want to treat specific areas like a knee, shoulder or lower back, a mid-size panel such as the RLF1500 is versatile, while a compact RLF750 is easy to position close to a single spot. For larger or multiple areas, step up to the RLF3000.
FAQ
Which wavelength helps deeper areas?
Near-infrared (around 810–850nm), because it penetrates further than visible red.
Is red light therapy drug-free?
Yes — it’s simply light at specific wavelengths.
How often should I use it?
A few short sessions a week on the area, building up gently, is typical.
