Green light exposure may reduce Fear based Anxiety and Opioid Use

I have known for decades that dentist use the color green in their offices to relax their patients. In addition, they often hang wall pictures of pastoral landscapes for the same reason.
Top 5 Color Schemes To Refresh Your Dental Practice | Dental Country
Dentists that ask what the best color scheme for a dental office is will typically have a hard time finding answers.The color theory also has a psychological element to it, meaning that the colors you choose will impact the environment around you. For many offices, these four colors have the top psychological impact on productivity.
Green – promotes harmony/balance, reduces anxiety, reduces eye-straining.
Blue – soothes/calms, promotes trust and communication, improves focus.
Yellow – creates optimism, promotes focus and innovation.
Red – boosts heart rate and blood flow, increases brain activity.In this study they used green light-emitting diodes (GLED) for one to two hours daily for 10 weeks.
Pilot Study Finds Green Light Therapy Improves Fibromyalgia Symptoms
Fibromyalgia patients exposed to green light therapy had significant improvements in their pain, sleep and quality of life.
Of course there is more than one way to skin a cat. More recently, researchers have found that wearing glasses with green lenses has a similar effect. Here, participants wore green eyeglasses for four hours a day for two weeks.

Case Report: Green Light Exposure Relieves Chronic Headache Pain in a Colorblind Patient (2022)
ABSTRACT: Patients with chronic headaches sometimes prefer non-pharmacological methods for pain management. We have shown previously that green light exposure (GLED, Green Light Emitting Diode) reversed thermal hyperalgesia and mechanical allodynia in a rat model of neuropathic pain. This effect is mediated through the visual system. Moreover, we recently showed that GLED was effective in decreasing the severity of headache pain and the number of headache-days per month in migraine patients. The visual system is comprised of image-forming and non-image-forming pathways; however, the contribution of different photosensitive cells to the effect of GLED is not yet known. Here, we report a 66-year-old man with headaches attributed to other disorders of homeostasis and color blindness who was recruited in the GLED study. The subject, diagnosed with protanomaly, cannot differentiate green, yellow, orange, and red colors. After completing the GLED exposure protocol, the subject noted significant decreases in headache pain intensity without reduction in the number of headache-days per month. The subject also reported improvement in the quality of his sleep. These findings suggest that green light therapy mediates the decrease of the headache pain intensity through non-image-forming intrinsically photosensitive retinal ganglion cells. However, the subject did not report a change in the frequency of his headaches, suggesting the involvement of cones in reduction of headache frequency by GLED. This is the first case reported of a colorblind man with chronic headache using GLED to manage his headache pain and may increase our understanding of the contribution of different photosensitive cells in mediating the pain-relieving effects of GLED.
