By moving to hour living, and reducing or ignoring the dark bit, we are effectively throwing away the advantages of millions of years of evolution.
The Darkness of Your Past Is The Light of Your Future
The effects of screwing up our body clocks are most readily observable in the growing army of night workers. Studies suggest that, even after years of night shifts, many workers never adjust to a regime that pitches them against our basic and hard-wired biology. Instead, they head wearily home to bed just as the morning light is prompting their body clocks to prepare for activity, and back again when the gathering dusk tells them to prepare for rest.
Once at work, overriding the craving for dark and sleep comes at a price.
Perhaps unsurprisingly, studies show that nightshift workers are at increased risk of a range of health problems, from stress, constipation and stomach ulcers to depression, heart disease and cancer. There is another theory that tries to explain the high incidence of breast and colo-rectal cancers in shift workers, however.

Melatonin is called "the Dracula hormone" because it always comes out at night. But its production can be severely reduced by bright artificial light. The effects of melatonin on health are not properly understood, but a number of scientists, particularly in America, are connecting low levels of melatonin with high levels of certain cancers in nightshift workers.
When the mice were subjected to constant light, cancer growth rocketed. Some have taken it further.
George Brainard, a neurologist at Thomas Jefferson University in Pennsylvania, has recommended that we all exercise a "prudent avoidance" of light at night to ensure normal levels of melatonin whether we work night shifts or not. Brainard's research has shown that the human body clock can be affected by light of short wavelength, which is more prevalent in artificial light used at night.
It also showed that melatonin production was reduced by just this sort of short wavelength light.

His is the kingdom, none has the right to be worshipped but He…. Professor Keith Moore one of the most famous embryology scientists in the world says: the embryo moves from one developing stage to another inside three veils that were mentioned in the holy Quran as God says: in three veils of darkness : the three veils of darkness may refer to: 1-The anterior abdominal wall, 2-The uterine wall, 3-The amniochorionic membrane. It has been proven scientifically that the development of the fetus in the mother's abdomen passes through three veils of darkness which are: the first darkness: is the darkness of the anterior abdominal wall, the second darkness: is the darkness of the uterine wall, the third darkness: is the darkness of the placenta and its membranes.
