In the current study, Burstein and colleagues found that of all light to which migraine sufferers are exposed, a narrow band of green light worsens migraine significantly less than all other colors of light and that at low intensities green light can even reduce headache pain.
Using Light Therapy
Green light therapy can be used at home to ease symptoms during a migraine attack or as a form of preventative care. Special LED "migraine lamps" emit a narrow band of green light that activates regions of the brain involved in pain processing less than other colors.
They found a significant decrease in blood flow velocity and a significant increase in serotonin levels 3 days after treatment. They also noted a 64% reduction in pain after treatment. They concluded that red light therapy may help modulate blood flow and serotonin levels in women with tension-type headaches.
Red and white LED lighting also trigger migraines. And as noted above, the color in LED bulbs is converted, so the color your eye perceives will not alert you to the prevalence of these more damaging color waves. In addition, LEDs use a flickering technology that triggers eye strain and headaches.
Purple – The Nightcap
Purple light can help you fall asleep. It also reduces emotional and mental stress. The nervous system and eyes are linked with this secondary colour. Contrary to red light, purple light decreases sexual desires.
What LED light color is best for your sleep? A red light color is best for sleep because it has a low color temperature, far lower than regular sunlight. You can be immersed in red light at night without giving your body a jolt and altering your internal clock as blue light does.
Green LED Light
The calming effect also has anti-inflammatory properties that soothe the surface of the skin. Green LED Therapy is used to treat dilated capillaries, sagging skin around the eyes, under eye circles, hyperpigmentation and sun spots.
Blue LED light is most often used to treat acne. It may do this by reducing activity in the sebaceous glands, so they produce less of the oil that can plug the hair follicles, leading to acne. Blue light may also kill acne-causing bacteria known as Cutibacterium acnes.
LED light therapy is now used by some aestheticians to help regenerate the skin from aging. It's also used for acne. Your healthcare provider uses red or blue light frequencies based on the skincare concern. Red is primarily used for anti-aging, while blue is used for acne treatment.
Yellow Light Therapy is used to increase wound healing, collagen induction, skin hydration and the overall health of the skin.
Melanin-Rich Skin
Blue light has recently been reported to lead to hyperpigmentation because it activates the production of melanin in your skin. Darkening can occur within 20 minutes of exposure while it also may lead to long term darkening, including melasma.
LED light therapy might: Treat acne. Reduce fine lines. Help with wound healing.
Purple LED is a combination of red and blue wavelengths, offering dual benefits of both skin clearing (blue) and anti-ageing (red). Purple is also beneficial for cellular oxygenation and regeneration to promote enhanced skin fitness and vitality. Yellow LED is used as a restorative therapy for sun damaged complexions.
Summary: A new study found that green light therapy resulted in about a 60% reduction in the pain intensity of the headache phase and number of days per month people experienced migraine headaches.
The color yellow elicits a feeling of comfort, while red tends to make people feel more hungry and impulsive. Marketing experts refer to the pairing of yellow and red as the "Ketchup and Mustard Theory." Green and earthy tones are used to convey a message of healthiness and environmental responsibility.
Red light and sleep
The theory is that red light wavelengths stimulate the production of melatonin. Melatonin is a naturally occurring hormone that helps you sleep. Your brain releases more melatonin as darkness falls and tends to release less when you're exposed to light.
Exposure to white light during the day can have positive effects, including boosting alertness and mood. Red light has no effect on the circadian clock, so you can use a dim red light at night. Yellow and orange light have little effect on the clock so you can use a very dim yellow or orange light at night.
Green LED Light
The green light helps to control hyperpigmentation of the skin and has a great regenerative power of skin nutrients damaged by sun and age. The green light acts against the melanocytes, the melanin forming cells in the inner part of the epidermis, inhibiting the production of excess melanin.
Red/Blue LEDs
Since photosynthesis peaks in the red and blue wavelengths it makes this spectrum, not only the most efficient for plant growth, but also the most energy efficient.
Purple. Simple color theory here—the combination of red and blue light can give you the anti-acne and anti-inflammation benefits that you're looking for without the risk of irritation from stronger topical ingredients. The color can also increase cell regeneration to help fade dark spots and even out your complexion.
You should install this light color in spaces where you often relax and read, such as your living room and bedroom. Its primary benefit is that it won't harm melatonin production in your body, unlike cold light.
What is red light therapy? Red light therapy (RLT) is a treatment that uses low wavelength red light to reportedly improve your skin's appearance, such as reducing wrinkles, scars, redness and acne. It's also touted to treat other medical conditions.
Yellow light therapy stimulates the production of red blood cells, which play a vital role in skin healing and skin cell rejuvenation. Because it has a shallow penetration level (compared to red and NIR light), it is ideal for treating a variety of skin conditions involving redness.
Over time, red light lamps will help: Restore tired-looking skin. Decrease fine lines and wrinkles. Diminish freckles.
Red LED light stimulates collagen, which is important for healing wounds. People who have had surgery for skin resurfacing have also had red LED light therapy after the procedure. Studies have found that this form of light therapy lowers redness, swelling, and bruising, and speeds up the healing process.
