The moon is not the source of medical problems, but all light is not the same. The visible spectrum to humans differs greatly in wavelength as does the rest of the spectrum. UV,IR,Microwave,Gamma, etc. are all forms of light. Some of these produce negative effects in the human body, including headaches.
