Scott Nelson – How Light Affects You: The Science Behind Red Light Therapy – HVMN Podcast

Check out the HVMN Podcast Episode Page & Show Notes

Key Takeaways

  • The benefits of red light therapy (RLT) include:
    • Better skin health, muscle recovery, athletic performance, less joint pain and inflammation, improved brain health and recovery time from a traumatic brain injury (TBI)
  • How does red light therapy work?
    • It enhances the mitochondrial activity within cells
      • Thus, the mitochondria make more energy (ATP), and with more energy, cells can function more efficiently, rejuvenate themselves, and repair damage
  • Americans now spend over 90% of their time indoors under artificial light
    • This lifestyle is radically different from that of our ancestors and we don’t yet know all of the negative effects this will have on our health
  • As a general rule, you can get the most natural red and infrared light during the morning and evening (when the sun rises and sets)

Intro

  • Scott Nelson is the co-founder of Joovv (@joovvsocial), a company that makes full-body red light therapy and photobiomodulation devices designed for consumer use

Books Mentioned

Who is Scott Nelson?

  • Scott spent most of his professional career in traditional medicine in leadership positions with some of the largest medical device companies in the world, including Medtronic and C.R. Bard
    • Scott studied biology in school, but he’s worked more on the business side of things in the medical industry

The Creation of Joovv

  • Scott’s wife and sister-in-law would constantly buy red light therapy packages at a local spa/salon
    • The two of them would go 4-5 times a week and see amazing benefits – reduced eczema, the disappearance of stretch marks etc.
    • But Scott realized that there was a big friction point – going to a spa all the time was an inconvenience
      • Additionally, the salon only had small handheld red light devices, nothing for personal home usage
    • At first, Scott thought the wide range of benefits being reported from red light therapy was exaggerated, but once he looked into the peer-reviewed clinical data, he was blown away by the research
  • Joovv launched its first red light therapy product in 2017
  • Fortunately, Scott hasn’t needed to raise capital for the business
  • He’s currently working on making Joovv products more convenient to use – once people see the benefits of red light therapy on a small device, they will likely want their larger products
    • Joovv products can easily connect together like legos
      • A customer can buy a single Joovv red light panel at first and then buy more panels in the future and connect them

Benefits of Red Light Therapy (RLT)

  • Benefits include better skin health, muscle recovery, athletic performance, less joint pain and inflammation, improved brain health and improved recovery time from a traumatic brain injury (TBI)
    • Because there are so many benefits, most people have a healthy dose of skepticism when it comes to the treatment
    • There is some benefit overlap between RLT and ketosis
  • How does red light therapy work?
    • Red light and near-infrared light fall into the “therapeutic window” – which is a narrow band of light wavelength that has been shown to enhance mitochondrial activity within the cell
      • The mitochondria are the powerhouse of the cell and help produce energy (ATP)
        • By increasing the function of the mitochondria using RLT, a cell can make more ATP. With more energy, cells can function more efficiently, rejuvenate themselves, and repair damage.
        • Since the mitochondria are found in cells throughout your entire body, the benefits of this therapy can be felt everywhere
          • There is some research showing that RLT could possibly also improve gut health and fertility
  • Scott recommends people use the full-body Joovv instead of the small handheld device to get the proper dosage and benefits
    • However, different doses are needed for different benefits
      • Ex. – To improve skin health, you need a lower dosage than for muscle recovery (but you can use a Joovv device for as little as 10 minutes and still get some overall health benefits)
  • As an FYI:
    • Red light penetrates only about skin deep, while infrared light can penetrate your bones (which is why it is used to heal the brain)
      • However, only about 15% of the infrared light will reach the bone so it does require longer usage

Why Humans Need Light

  • Americans now spend over 90% of their time indoors under artificial light – this is a dramatic change that has happened in the last 50-75 years
    • This lifestyle is radically different from that of our ancestors and we don’t yet know all of the negative effects this will have on our health
  • People are becoming more aware of the advantages and disadvantages of certain wavelengths of light
    • Blue light is associated with midday sun and is known to disrupt people’s circadian rhythm and keep them awake
      • Even Apple knows about this and introduced a new option for iPhone users to turn off blue night
    • Just as different foods are meant for different scenarios (have coffee around noon but not past dinner time), the same can be said for different light colors
  • There have been a lot of scientific studies done on red light as it’s in the therapeutic window
    • However, this doesn’t mean yellow or green light has no effect on the body – it just hasn’t been studied
  • As a general rule, you can get the most natural red and infrared light during the morning and evening (when the sun rises and sets)
