A.) Infrared

• Really cool research showing that Red Light Therapy had many beneficial uses

  • Simple red light: (aka “color therapy”)

    • Has many benefits- red light may be useful with just an extremely cheap simple light (sleep/ alertness/ mood/ hormones). (VERY GOOD EVIDENCE)

  • Infrared light (different type of light)(more powerful/ brighter):

    • Has very different benefits for skin/ scars/ wounds/ healing/ acne. Can penetrate into the deeper layers of the skin. (VERY GOOD EVIDENCE)

B.) Red Light Sauna Vs. Traditional Sauna

(Long story short: More reasearch is needed)

• There are 3 main different types of red light saunas

  • Near Infrared

    • Less penetrating in the skin…. But likely it is exacatly the same benefits as a traditional “steam style sauna”

      • Still good for skin, good for cardiovascaulr health, good for mental health.

      • Because the light rays are less penetrating…likely arne’t getting any additional benefits

  • Mid- Infrared

    • In between

  • Far Infrared

    • Deeper penetrating… so IN THEORY- you should get similar benefits as the typical far infrared - Red light therapy (as seen above in section A)….. However in practice…. these lights are typically much less powerful…..It is unclear if you are getting bright enough/ powerful enough light rays. (AKA more research is needed)

  • Full Spectrum

    • Combination of the 3
