We know for certain that processed materials within a built environment like carpet and plastic have a strong effect on levels of depression. We know that people get agitated by fluorescent light compared to incandescent light. We know that a lack of natural airflow in and out of buildings affects the immune system and circadian rhythm of people.
When people are surrounded by natural materials, we know their blood pressure drops, they become happier, and their brain activity is increased. It's because those materials increase the amount of energy they spend acclimating themselves to the nuances of natural environments. They are much more aware. There is a huge therapeutic value to natural surroundings the same way there are to natural foods.
