I see a lot of talk on Facebook about red light and people suggesting LED light and infrared saunas, all grouped into red light. Here is the difference:
Red Light Therapy (like the TGA-approved BlockBlueLight device I use) uses specific wavelengths of red and near-infrared light that pe*****te the body’s tissues and help support cellular energy, circulation and recovery.
LED light therapy is simply the type of bulb being used — many devices use LEDs, but not all LED lights produce the therapeutic wavelengths needed for true red light therapy. There can be a huge difference in NM light
Infrared sauna light is different again. Infrared saunas use heat to warm the body and promote sweating and relaxation, whereas red light therapy is not about heat — it’s about light stimulating the cells.
So while all three involve light, they work in very different ways. If you’re curious about how red light therapy may support recovery, inflammation or general wellbeing, feel free to reach out and I’m happy to chat. ✨
BREAKDOWN OF LIGHT/COLOUR + NANOMETERS
Each colour in the visible spectrum corresponds to a specific wavelength range:
Violet/Blue: ~400–490 nm
Green: ~490–570 nm
Yellow: ~570–590 nm
Orange: ~590–620 nm
Red: ~620–700 nm
Invisible Light (Nearby Spectrum):
Ultraviolet (UV): Wavelengths shorter than 400 nm.
Infrared (IR): Wavelengths longer than 700-750 nm.
LED Technology: The colour of an LED is determined by its peak wavelength in nm (e.g., a blue LED is around 450-470 nm, while a red LED is around 630-660 nm).
Red Light Therapy: Devices typically use wavelengths in the red (600-700 nm) and near-infrared (700-1200 nm) ranges for therapeutic effects.
