Does Red Light Therapy Actually Work?

Wondering about red light therapy benefits? Did you know in the early 1990s, NASA found that red light could actually activate plant growth in space in the absence of sunlight? They found that the intense light from red LEDs promoted the growth and photosynthesis of plant cells. But could red light also benefit the human body?

What is Red Light Therapy

Red light therapy (RLT) is the application of light (usually low power laser or LED) to safely penetrate the body’s surface tissue. RLT used here at Perspire Sauna Studio combines visible red light (650nm) and invisible near-infrared (850nm) wavelengths to offer you an optimal color light therapy experience.

How Red Light Therapy Works

Red Light provides the most proven and effective therapeutic wavelengths to the entire body. This process, formerly known as Low Level Light Therapy (LLLT) is now known as Photobiomodulation (PBM), defined further as a form of light therapy that utilizes non-ionizing forms of light sources, including lasers, LEDs, and broadband light, in the visible and infrared spectrum. It is a non-thermal process involving endogenous chromophores eliciting photophysical (i.e., linear and nonlinear) and photochemical events at various biological scales. ¹

Red Light Therapy Benefits

Many of our guests have asked, what are the benefits of Red Light Therapy. After the brilliant scientists at NASA discovered RLT helped plants grow in space, RLT was then extensively studied for its ability to increase energy levels inside human cells. Not only was it concluded that RLT does indeed help to increase energy via the production of Adenosine Triphosphate (ATP), it has also been shown to:

  • Reduce post-injury swelling & inflammation ²
  • Reduction of oxidative stress ²
  • Increase athletic recovery ³
  • Reduce acne inflammation & breakouts ⁴
  • Enhance weight loss ⁵,⁸
  • Reduce fine lines, sagging skin, sun damage and wrinkles ⁴
  • Stimulate hair growth ⁶
  • Tissue regeneration ⁷


Yes, Red Light Therapy does work! Above are just a handful of the benefits that RLT (PBM) are proven to provide. Our studios, here at Perspire Sauna Studio, offer medical-grade Red Light Therapy in addition to infrared and light therapy colors. This unique combination of light therapies delivered holistically in every 40-minute infrared sauna session provides the most optimal wellness experience for inner and outer transformation.
