What is red light therapy and how does it work? Most people think of light as something that only allows for visibility of their direct environment. (Sun)light, for instance, allows you to see what’s going on around you. And at nighttime, the absence of light makes your environment invisible. Without going into too much detail, the energy-producing processes in your cells are also affected by light in your environment. That basic process of light absorption by photoreceptors brings many fundamental health benefits. This red and infrared light therapy is also frequently described with other names, such as “Low Level Laser Therapy (short: LLLT)”, “LED light therapy”, “photobiomodulation”, and “red light therapy”. In this episode of The Sauna Show both Sebastian and Johannes talk about the fundamentals of understanding Red Light Therapy, how it works, and the options you have out in the market today.
