The most recent Regence insurance newsletter had a lead article about how the health of people living near a park was improved. They cited some fairly obvious reasons for this, primarily the close proximity of a green quiet place that begged people to come walk and exercise there. There could be an added reason that spending time in a park would help your health. That reason is centered in your adrenal glands. Color research has demonstrated that the cool colors of green and blue have calming effects on one's mood and energy. The color green is known in naturopathic medicine circles for reducing stress and balancing the adrenal response to stress. Combining exercise with the color green has a more powerful stress reducing effect than either by itself.
My hypothesis for why green helps is tied to a little studied area in life sciences concerning energy effects. The color green occupies a specific place on the larger electro-magnetic spectrum with a particular energy frequency of 520-540 nanometers. It is my belief that this particular energy frequency has an impact on the various cells in the body, creating a molecular effect that has a dampening effect on excitability. There is so much about the world that we do not know. It is exciting to think about all the possible ways our health is impacted. So, get out there, surround yourself with green, and take a long refreshing walk while the weather is beautiful!
