Old Woman/Young Woman - But What Do You See?Like art , symbols can literally alter your brain chemistry. Whether you are made to feel elevated or depressed, happy, sad, angry, or any feeling in the emotional spectrum, by viewing the imagery your nervous system is affected, and your brain chemistry is altered, changing your mood, behavior, and state of mind. Yes, pictures and colors DO affect you both psychologically and biologically, and this is used every day in hospitals, prisons, restaurants, and many other facilities (Think green room, or placing newborns under blue light to remedy yellow jaundice).
In short, light affects you, because it is energy entering your body.
