Why Red Light Therapy is One of the Best Healing Tools

Article at a Glance: 

  • Red light therapy, also known as photobiomodulation or LED light therapy, is considered a safe, painless, non-invasive, and drug-free form of treatment for healing the skin and body. 
  • Red light can penetrate the body 8-10 millimeters into the skin — reaching deep into tissues, muscles, and bone. 
  • Many studies indicate that red light therapy has numerous potential health benefits, including but not limited to: improved mitochondrial function, improved blood circulation, muscle recovery, and collagen production, as well as decreased pain and radiant skin.
  • Red Light therapy also has anti-inflammatory effects that may help heal a wide range of issues from the surface of the skin all the way down to the bone.
  • TrueLight LED light therapy products use a patent-pending combination of light within the 625nm – 900nm range, which are the most effective for healing wounds and various skin conditions.

How does red light therapy work?

Red light wavelengths affect bodily cells on a biochemical level by increasing mitochondrial function – the ability to produce cellular energy. The more cellular energy production, the better the body functions as a whole. When red light wavelengths are used on the skin’s surface, they can penetrate 8-10 millimeters into the skin.

What are the benefits of red-light therapy?

Red light therapy works from the inside-out to enhance mitochondrial function in cells. This, in turn, leads to several skin benefits.  Red light can help the body decrease skin inflammation, smooth skin tone, repair sun damage, fade scars and stretch marks; it can even build collagen in the skin, which can reduce wrinkles and help heal wounds.  Red light also positively impacts the lymphatic system by increasing blood flow and subsequently improving your body’s ability to detoxify.

Key Benefits:

  •  Enhanced blood circulation
  •  Anti-inflammatory effects
  •  Increased muscle recovery
  •  Increased collagen production
  •  Radiant skin
  •  Reduces scars, wrinkles, & fine lines
  •  Speeds wound healing
  •  Enhanced fertility
  •  Increased testosterone
  •  Decreases pain

Red light therapy, or light box therapy, has been around for over 40 years. It emits specific wavelengths of light to restore, repair, and protect body tissue that is either injured, degenerating, or at risk of dying.  While varying wavelengths affect the body differently, the most effective wavelengths for red light therapy and healing range from 625nm-900nm. The patent-pending TrueLight™ Energy Square concentrates specifically on 630nm, 660nm, and 850nm wavelengths.

Why specifically use 630nm, 660nm, and 850nm wavelengths?           

Various research projects promote the benefits of different wavelengths for the treatment of certain conditions. It is generally agreed that wavelengths between 625nm and 900nm are the most effective for healing wounds and other skin conditions.  At the lower end, 630nm and 660nm appear to be favored. At longer wavelengths, 850nm and 880nm are the most beneficial.

A University of Chicago study discovered that the average wavelength of cell tissue in the human body ranges between 600nm and 720nm, with 660nm being the mid-point.  660nm works better than any other frequency because it is closer to the resonant frequency of cell tissue, allowing it to absorb better in hemoglobin. This is a red protein responsible for transporting oxygen in our blood.  Your mitochondria can absorb red light easily at the 630nm and 660nm wavelengths, which roughly coincide with the absorption peaks of cytochrome c oxidase (the target of light therapy).

The mitochondria’s metabolic function is usually restricted by a biologically active molecule called nitric oxide, which binds to cytochrome c oxidase and prevents it from using oxygen. Red light detaches this molecule, allowing cytochrome c oxidase to resume its energy-producing metabolic function.

Use pulsating or steady light for deeper healing and pain relief

It has been discovered that when LED lights are pulsed, body tissue can heal more rapidly.  When it is given a continuous burst, it sedates the cell and relieves the pain. When a single-frequency pulsed light hits the cell, it stimulates the cell to start producing more protein than it normally does, as a result, the cell heals faster.  Even when the LED light source is taken away, the cell continues its healing. As opposed to the pulsing light that is best for healing, a continuous, steady light beam can remove/dull pain, reduce inflammation and allows muscle tissue to relax.

Therapy Light Pulsing Options

Interested in getting a light therapy device for home use? The NEW TrueLight™ Energy Square delivers patent-pending optimal Near Infrared, Deep Red, Red, and Yellow/Amber wavelengths with steady or pulsing modes.  TrueLight’s unique combination of wavelengths can react with cellular mitochondria to increase adenosine triphosphate (ATP) production. In turn, increased ATP production can lead to faster production of collagen, vascular structures, DNA, RNA and other materials that are essential to your body’s healing process.  These wavelengths may enhance blood circulation, reduce wrinkles and fine lines, increase muscle recovery, decrease pain and reduce joint inflammation as well as skin redness/irritation.
