green light exposure reduces anxiety in fibromyalgia, blue light does not
In patients with fibromyalgia, green light significantly reduced anxiety whereas blue light did not, demonstrating color-specific differential effects on psychological stress responses.
What this means for you
Not all light is the same — green wavelengths appear to calm the nervous system in a way blue light simply doesn't. For anyone carrying chronic tension or stress, this color-specific response suggests that the right light environment may genuinely support a quieter, less anxious state of mind.
