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).
During millions of years of evolution, man lived in a system strictly dependent on the climatic conditions that surrounded him. Social habits were strongly influenced by the seasonal rhythm and the time of exposure to natural sunlight. The expansion of artificial electric light, which began in the last century, finally allowed the independence of the natural photocycle.
The practical convenience of artificial light has led to underestimating the physiological implications of replacing daylight. Modern man not only lives in artificial environments but also is exposed to an immense amount of radiation from electromagnetic fields with different intensities from the planetary radiations to which man has been exposed for millions of years.
Light awakens nature, generates food for plants, and protects us from bad energy. Let’s discuss why do we need light in detail:
