Earth has been bathed with light from the Sun ever since; it is our most important source of energy. Sunlight warms us, causes weather patterns, allows plants to manufacture oxygen and our food from carbon dioxide and water, and it allows us to find our way around in the daytime!
Light is the source of all life on our planet. The importance of light could be comprehended as plants synthesize nutrients from light using chlorophyll, and filter the air we breathe. Animals and humans depend on plants for survival. Therefore, everything depends on the light in some way.
The human body needs to be exposed to natural sunlight and its rhythm to function properly. The effects of light on endogenous production of vitamin D and melatonin are well known, as well as the role they play in emotional dysfunction such as SAD (Seasonal Affective Disorder).
