Sunlight Deprivation
Fire element in the form of sunlight triggered the chemical reactions that led to the development of life on Earth. Without sunlight living things would be unable to survive. Artificial lighting has given us a new kind of control over our interior environment. This has given rise to two peculiar situations, one, it has made underground work places possible. Second, it has encouraged late night work or leisure, which automatically makes you wake up late in the morning. Both these situations depend heavily on electric lights, but the light they emit does not have the same health benefits as natural sunlight.
The difference between the sunlight and artificial light begins with the composition of colors. Ordinary incandescent bulbs produce light predominantly from red end of the spectrum, and have small amounts of blue. Cool white fluorescent lights produce more of the blue and green wavelengths but still do not mimic natural sunlight. Neither emits any ultraviolet light.
When they replace sunlight as a primary source of light, the artificial lights with their distorted spectrums disturb the balance of five elements in your body. Of the natural sunlight that reaches the Earth, 5 percent is ultraviolet light. Ultraviolet rays are responsible for causing sunburn, skin ageing and even skin cancer, but in small doses however, these rays are essential for good health.
Ultraviolet light triggers the synthesis of vitamin D in the body, which is vital for absorption of calcium. Capacity of white blood cells to combat infections is doubled by appropriate UV light exposure. Early morning sunrays contain non-burning amounts of UV rays required by the body, which the late risers get deprived of. Sunlight also affects the thyroid gland, which produces a hormone called thyroxin, which regulates the overall body metabolism and energy levels.
Sunlight is essential for setting the body's clock by influencing our sleep/wake cycle. The light-receptive cells in the eye relay messages about the quality of light to the pineal gland in our brain, which produces a hormone, called melatonin making us feel drowsy. If melatonin is natures sleeping draught, sunlight is its alarm clock. Do not lead a life style, which can cause sunlight deprivation. Remember artificial lighting can never replace the real thing.
