Light Therapy - The Quick & Essential Science
Does Light Therapy Really Work?
We'll dive deep and take an in-depth look into this question in this article. The short answer; Yes. Light therapy is an effective health modality that’s been widely studied and tested. With so many therapy options, it’s normal to wonder “What is light therapy?” “How does light therapy work?”, and "What does light therapy do?" Continue reading for more about the science behind light therapy, and how a light therapy treatment affects your body at a cellular level.
What Is Light Therapy?
NASA originally began experimenting with red light therapy on plant growth in space and then to help heal wounds in astronauts. Like many developments, other potential uses began to be investigated.
Light Therapy is a treatment that uses low wavelength light to work on the “power plant” in your body’s cells called mitochondria. With more energy, other cells can do their work more efficiently, such as boosting new cell growth, rejuvenating skin, repairing muscle tissue, and shortening recovery time after injury. More specifically, certain cells absorb light wavelengths and are stimulated to work more efficiently, just like absorbing sunlight & drinking water help keep your body hydrated and healthy.
How Safe Is Light Therapy?
Red light therapy is widely regarded by medical professionals as effective & safe. This therapy is not toxic, not invasive and not as harsh as some topical skin treatments. Unlike the cancer-causing ultraviolet (UV) light from the sun or tanning booths, Light Therapy doesn’t use this type of light. To use Purelight devices as safely as possible, it is recommended to start with shorter therapy sessions before increasing session lengths.
How Effective Is Light Therapy?
Over 125 research studies concluded light therapy to be a very effective and efficient method of treatment. Researchers found shorter recovery times after injury, faster muscle regeneration after a workout, and most importantly a drastic reduction in physical symptoms of joint pain and soreness. It’s also important to note that 73% of research subjects reported feeling relieved after treatment sessions along with having a “more effortless and easier” range of motion while doing physical activity.
Red vs Infrared Light Therapy
Light Therapy can be measured in units called nonometers (NM). Red light wavelengths measure from 400nm-700nm, whereas infrared light can be measured from 700nm-1000+nm. Residing right next to near infrared on the spectrum, red light can (obviously) be seen! Many red light therapy systems use small amounts of infrared along with red LED lights, and as we’ve uncovered infrared penetrates deeply while red light works on the surface of the skin. Tissues that don’t receive great circulation because they have been injured can also benefit greatly as infrared heat can provide healing and skin regeneration. Infrared heat promotes the rebuilding of injured tissue by having a positive effect on the fibroblasts (connective tissue cells necessary for repair), increasing the growth of cells, and DNA and protein synthesis necessary during tissue repair and regeneration. This increased circulation, along with an increased blood flow and oxygenation, can also provide relief for those experiencing chronic pain and other conditions.
Although infrared is classified as light energy, we don’t see it; we feel it as warmth. Because all humans produce infrared, it’s safe, natural and easily absorbed by our tissues. During and after absorption users notice effects such as pain relief, increased circulation (blood flow), weight loss, detoxification, skin rejuvenation, relaxation, improved sleep and much more! For millennia, people all over the world have used infrared to improve their health and assist with boosting the metabolism, reducing inflammation, lowering side effects of diabetes, reducing allergy symptoms, improving heart function and bettering their quality of life. How does infrared do it? When it enters the body, it breaks up fats and toxins that are trapped in water molecules, it makes us sweat to let them out and therefore an infrared session is one of the best ways you can naturally detox your body!
