Science behind sleeping with light off

in StemSocial2 months ago

The remembrance of my late father while on his bedroom at night has not totally vanished away from my memory and I believe it will not vanish forever, I remember how he used to sleep by switching his light off and playing his favorites lyrics known as "Apala music" the likes of late Musiliu Ayinla, late Epo akara, late Yusuff Olatunji and the popularly known as doctor of fuji 'late Sikiru Ayinde Barrister'. Those who come from western part of Nigeria will relate this kind of lyrics better, especially those who are thirty (30) years and above.

I used to prefer sleeping with him because of the enjoyment that can not be compared with sleeping elsewhere. However, I was not formally inform on why I should be sleeping while switching the light off but I assumed it as a norm to switch light off while sleeping with him for more than three decades ago, even when I did not know about science let alone knowing the science behind the notion.

Although, the most common sources of light then was light underneath the ceiling, lamps and the televisions. Light from other electronic devices, like computers,cellphones and tablets were not common during that era.

Are there any evidence from scientific research on why one should sleep while the light is off?

Research has revealed that there is a serious health risk, and danger to sleep while the light is ON, according to a senior lecturer in Landscape Architecture at the Melbourne School of Design, Dr Margaret Grose asserted that there is a need for urban planners to ponder on the health implications related with street lighting and environmental issues, although she was not specific about sleeping with light on.

However, the American Medical Association published a ground-breaking study in 1980 which asserted that Artificial light at night (ALAN) used to derange the creation of melatonin in the body. The term melatonin has been attributed to a substance in our body that is responsible in control of energy and appetite, mood and sleep-wake cycle.

According to a professor of neuroscience at the University of Melbourne,Professor Trichur Vidyasagar, who also affirm the fact that there is a nerve cells which is responsible to control circadian rhythms, it is found to be located at the back of our eyes which contain a special pigment that is sensitive to ray of light, especially blue light. However, according to him exposing this cell to too much of lights at night may result to rough sleep.
