    Why You Need To Take Advantage Of Red Light Therapy

    By Catherine on April 14, 2018 Last Updated December 3, 2020 6 Comments | No Medical Advice | This Post Contains Affiliate Links

    Why I'm Addicted To Red Light Therapy | Butter NutritionMy fascination with light therapy began about five years ago while studying the work of Dr. Ray Peat. As I studied his work I would frequently find references to the importance of bright light on your skin to signal your cells to create more energy or adenosine triphosphate (ATP) as well as its ability to aid in hormone synthesis (the production of sex hormones).

    I was fascinated with what he said about red light in his work, such as...

    “Penetrating red light is possibly the fundamental anti-stress factor for all organisms. The chronic deficiency of such light is, I think, the best explanation for the deterioration which occurs with aging. Enzyme changes, free radical changes, structural and respiratory changes are all involved as consequences of darkness stress.” - Ray Peat, PhD

    Ever since, I've been on a quest to get more light of any kind into in my life, especially in Seattle's gloomy winter months...

    What is Red Light Therapy?

    In talking about red light therapy, the terminology can be a little confusing. Red light therapy is also known as photobiomodulation (PBM) or low level light therapy (LLLT) and sometimes cold laser therapy. It's considered low level because it has a lower energy density when compared to higher intensity laser therapies.

    Light therapy comes in all sorts of wavelengths:

    Ultraviolet or UV light:  300-400 nm
    Natural Sunlight: 400-700 nm
    Red light: roughly 620-700 nm
    Near Infrared light: 700-1000 nm

    Red and near infrared light fall into what is known as the optical window or therapeutic window between wavelengths of 650 to 1350nm. Because wavelengths in this range are easily able to penetrate human skin tissue, they are commonly used in PMB or LLLT. Wavelengths from 600-700nm (red light) are used for superficial tissue while longer wavelengths of 780-950nm (near infrared light) are used on deeper tissue. [7]

    Why You Should Take Advantage of Red Light Therapy | Butter Nutrition

    In nature, you'd get the most red light therapy at sunrise and sunset because that is when the sun gives off the most red (660nm wavelengths) and near infrared light (850nm wavelengths). However, due to modern life you're probably missing out to some degree on the sun's natural red light.

    Benefits of Light Therapy

    The benefits of light therapy are plentiful, so let's get started...

    First we know that light therapy has been found to be good for skin rejuvenation, things like:

    • reversing collagen down-regulation
    • skin appearance in aged/photoaged skin
    • improvement in wrinkles
    • faster wound healing
    • improved scar appearance

    We also know that light therapy is helpful for hair health, such as in cases of:

    • alopecia areata
    • androgenic alopecia

    Light therapy is also helpful for pain and inflammation, specifically:

    • rheumatoid arthritis
    • muscle recovery
    • carpal tunnel syndrome
    • low back pain

    And then it's also great for energy production and thyroid health:

    • improves thyroid function

    And finally supportive of overall health...

    • exercise performance
    • eye health
    • hormone health

    Pretty impressive, right? And there is far more... just take a look at this awesome spreadsheet comprised of thousands of studies on light therapy! It's pretty amazing that there is this much research on light therapy, but it's still not quite "mainstream."

    How To Take Advantage Of Red Light Therapy

    Why You Should Take Advantage of Red Light Therapy | Butter Nutrition

    About a year ago I started using red light therapy at my local tanning salon, which is basically just a tanning bed that has the UV lights replaced with red light bulbs. I would go several times per week and stay for 20 minutes a session if I could find the time. It was time consuming, and added up to about $360+/year (not including the gas it took to drive there), so it didn't stick. I gave it up after a few short months.

    Other options for red light therapy including purchasing your own device. There are units available of all sizes and it really just depends on how big of an area you want to treat and how long you you want to spend treating it. Many of these devices are quite small and it would take quite a while to expose your whole body for the suggested treatment time.

    I wanted to find a way to treat my whole body at home but in a lot less time...

    My Choice For Red Light Therapy

    Back in March, the Joovv Original Combo unit came into my life. For the several months I've been using my Joovv light for about 10-20 minutes per day (5-10 minutes front & back) and while it's still early on I'm impressed by the results, especially just the way I feel after using it! I'll of course continue to update this post as time goes on. My dog really enjoys it too 🙂

    Why I'm Addicted to Red Light Therapy | Butter NutritionJoovv's red light therapy units are perfect for the average person looking to hack their health in convenient ways that easily fits into  the modern lifestyle. And they have a combo unit that combines red light wavelengths for superficial tissue with near infrared wavelengths for deeper tissue so you get the best of both worlds in one treatment.

    Ready to join me and try red light therapy at home? You can pick out your own Joovv red light therapy unit here. They even have a 60-day trial and hassle-free return policy so you can't go wrong!

    Free Report: How To Reverse A Slow Metabolism

    When your body decides to slow your metabolism it’s all about one thing: survival! It’s not about your body trying to conspire against you and ruin your life. It’s your body making a wise decision to sacrifice long-term health for short-term survival because it’s being told to do so (usually through food/nutrient scarcity). The slowing of the metabolism allows your body to go longer on less food. The body also tends to hold on to fat as a protective mechanism, which isn't exactly what most people are going for!

      What do you think of near infrared saunas? I was considering purchasing one to help with thyroid and hormone imbalances?

      I have been using LED red light therapy for the treatment of interstitial cystitis . I am using a combination of the V-Fit for pelvic floor strength (internal device) and a light from Red Light Man (external fixture) . I use the V-Fit every morning for 10 minutes, and the Red Light Man for targeted external treatment for 15 minutes each evening.

      If I am having a really bad flare up I will either add additional sessions with either device, or increase the time with the Red Man Light to 20 minutes, depending on how intense the flare up is. It has helped me reduce the number of flares, and get through those times where the episode could not be suppressed.

      I have been using the red light therapy for about 4 months. In that time I have eliminated the use of all the oral medications I was using to help me get through flare ups.

      Another way that red light therapy can differ is the actual light used. Often nowadays, LEDs are used, but low-energy lasers can also be used. The light produced can vary between machines, with different wavelengths being emitted, such as infrared light. Different wavelengths can affect different symptoms differently, so it is good to find out which wavelength is best suited to treat your condition.
