How Does Red Light Therapy Work?
In the early 1990s, RLT was used by scientists to help grow plants in space. The scientists found that the intense light from red light-emitting diodes (LEDs) helped promote growth and photosynthesis of plant cells.
Red light was then studied for its potential application in medicine, more specifically to find out if RLT could increase energy inside human cells. The researchers hoped that RLT could be an effective way to treat the muscle atrophy, slow wound healing, and bone density issues caused by weightlessness during space travel.
You may have heard of red light therapy (RLT) by its other names, which include:
- photobiomodulation (PBM)
- low level light therapy (LLLT)
- soft laser therapy
- cold laser therapy
- photonic stimulation
- low-power laser therapy (LPLT)
When RLT is used with photo sensitizing medications, it’s referred to as photo dynamic therapy. In this type of therapy, the light only serves as an activating agent for the medication.
While there’s a fair amount of evidence to show that RLT may be a promising treatment for certain conditions, there’s still a lot to learn about how it works, too.
The Right Wavelengths That Make Red Light Therapy Effective
Light Therapy uses two specific wavelengths, proven to be therapeutic. The red and infrared light that falls within the wavelength range of 650-850 nm is extremely beneficial and often referred to as the “therapeutic window”. These specific wavelengths of light can be bio active in humans and will affect the cells in a positive way. Red light emits between the 620-700nm range of the spectrum. The red light or visible light has its own positive effects on the human cells and skin. The infrared wavelengths in the 800nm penetrate the tissues deeper and active the mitochondria as proven in many studies. We know that sunlight affects us in a positive was, so red light therapy mimics the beneficial wavelengths that sun exposure would give the body. Sunlight includes a component of red light; it is this light wavelength that contributes to the enhanced sense of positive mood we experience after a few hours outdoors. Red light therapy devices, such as those offered by Solas harness the regenerative healing red light wavelengths, without the more problematic UVA and UVB light rays that can cause skin cancer and premature aging.
How does red light therapy help me?
Red light is thought to work by producing a biochemical effect in cells that strengthen the mitochondria. The mitochondria are the powerhouse of the cell — it’s where the cell’s energy is created. The energy-carrying molecule found in the cells of all living things is called ATP(adenosine triphosphate).
Red light therapy, therefore, is the therapeutic tool that applies red and infrared light wavelengths to assist with the treatment of health issues and promote overall health. You may have also heard of red light therapy and its other common names:
- Low level light therapy (LLLT)
- Photobiomodulation (PBM)
- Soft laser therapy
- Photonic stimulation
- Low-power laser therapy
- Cold laser therapy
During a red light therapy treatment, chromophore within our cellular mitochondria absorb red and infrared light photons and convert them into energy (ATP). Mitochondria are the powerhouses of cells, responsible for making adenosine triphosphate (ATP), the cell’s form of energy, and enhancing the consumption of oxygen. Once the energy is absorbed the cells utilize the energy and create new proteins, elastin, and collagen etc.
Here are many benefits of red light therapy. It has been shown that the red light can increase circulation and therefore oxygenation and nutrient delivery to the skin, as well as increase the activity of fibroblast, which aid the production of collagen and elastin. The improved circulation can reduce inflammation and aid lymphatic drainage which clears waste products away from the skin. It can also promote the production of DNA and ATP (cell energy).
Red light therapy can, therefore, be used to treat or complement the treatment of a number of conditions. From reducing the appearance of fine lines and wrinkles to soothing psoriasis and eczema. When treated using an appropriate light source and regimen it can work very successfully, with noticeably results very quickly.
Red light therapy only takes 5-10 minutes on average a day per treatment. Can you spare this amount of time a day to see all of the great benefits of red light therapy? When you are feeling unwell or stressed the ability of our cells to work effectively has dwindled. We need the right food, mindset and sunlight exposure.
