Light hitting the retina that's located at the back of our eyes triggers electrical signals in the retina and the brain. The red and blue light create the most massive signals, with green light making the smallest signals. This explains why the green light is the least likely to bother those with light sensitivity or photophobia. GLT requires specialized lamps that produce a band of green light while filtering out other light types.
GLT is a non-invasive light treatment that uses low-level light to stimulate the body’s natural healing processes while providing pain relief. Research suggests that it may be useful in treating a wide variety of conditions, including sleep disorders, chronic pain, and skin problems.
Green light therapy for migraines
If you are getting more headaches or prone to migraines due to stress and your regular Tylenol won’t cut it, you might want to try green light therapy for some relief.
Studies and research published in Nature Neuroscience have found that a very special narrow band (520nm +/-10) of green light can help people relieve migraines by producing smaller electrical signals in the eyes and brain. Unlike bright light, the precise band of green light’s soothing glow can help them get back to their everyday lives.
So how does green light therapy at home really work?
For years, the effects of green LED light on the brain have been researched and well-documented. Several studies prove that green light resets the circadian rhythm through melatonin, the hormone that regulates our sleep-wake cycles. The human eye has a special photoreceptor system that picks up light and elicits non-visual responses while sending signals to the brain to reset the body’s internal clock and altering melatonin production levels.
Skin benefits
Many skin problems that are treated with green light include acne, psoriasis, eczema, and dermatitis.
The most common use of green light therapy for face that we use today is for skincare treatments to target dark circles, pigmentation, broken capillaries, and sunspots. When it comes to treating these skin concerns, it is more advisable to fade them with the best green light therapy device or face mask instead of fading creams.
When you treat your skin with green light the melanin in your skin absorbs the green light that the device emits with wavelengths between 500nm and 540nm. As a result, the body recognizes and breaks down the particles of melanin that it encounters. Leaving you with clear skin and reducing the risk of such skin blemishes re-occurring in the future. It also calms irritated or over-stimulated skin.
In addition, green light also decreases spider veins and rosacea by causing the small blood vessels that lie just beneath the skin to close down and disappear. Therefore, making their appearance less visible.
How to use light therapy devices
Many resources suggest light use of 15-20 mins a day for 3-5 times per week, as a general guideline.
However, that may be true in red light therapy but not necessarily the right way to approach GLT. Low levels of light have a much better effect on repairing and stimulating tissues than higher levels of light. It is important to consider the time of exposure and concentration of the light source you are using. With that said, sitting in front of your light panel all day may not be yielding the best results for the treatment and that more is not always better when it comes to light therapy exposure.
Green light therapy benefits
It is a non-invasive treatment and doesn’t require any medication. You can control when and how to use green light therapy devices from the comfort of your home. It is also relatively inexpensive compare to in-clinic treatments.
Many people are able to go about their lives, working, being with family, run errands, as usual, with no green light therapy side effects while taking advantage of the benefits it offers to your overall health.
Take the natural approach that lowers the risk and cost of managing pain, migraines, and skin conditions, with the evidence accumulating (GLT) deserves the green light.
