This color is so powerful that it can modify your sleep.
This is the cyan, ent r and the green and the blue, which has a hidden factor that can alter your desire or not to sleep.
According to biologists at the University of Manchester, United Kingdom, high levels of cyan keep people awake, while reducing exposure to this color can help to cause sleep.
The impact is felt even if the color changes are not visible to the eye, says the study.
The researchers, led by Professor Rob Lucas and Dr. Annette Allen, aim to produce devices for computer screens and telephones in which cyan levels can be increased or decreased.
Scholars of the dream had already verified that there are links between colors and sleep, and it was identified that with blue light it is more likely to be delayed.
There are “night mode” settings for phones and laptops that reduce blue light in an attempt to decrease the damage.
But research by biologists at the University of Manchester and in Basel, Switzerland, published in the journal Sleep , showed the particular impact of cyan color.
When people were exposed to more or less cyan, the researchers were able to measure different levels of the sleep hormone melatonin in people’s saliva.
Professor Rob Lucas explained that it was not necessary for anyone to see the difference in colors, since the body reacted to the change even if it was not visible to the naked eye.
He said that this could also affect other colors that were created using cyan.
For example, there are shades of green that can include cyan, which can also be achieved using other color combinations.
The researchers suggest that versions of cyan colors could be used on computer screens if the goal is to keep people awake , such as those who work and who need to be alert during the night.
Or there could be another version of the same color but without cyan that could be used if the goal is to reduce sleep disruption.
The research used colors that adapt to include or exclude cyan in a film and found changes in spectator drowsiness and melatonin levels in saliva.
The research team says that with this discovery applications could be created on computer screens, televisions and smartphones.
“This result is exciting because it tells us that the regulation of exposure to light cyan alone, without changing the color, can influence how sleepy we feel,” Professor Lucas said.
He added that it could help families with teenagers who use mobile phones at night and whose sleep is being affected .
