Biological Clock Depends On Color Of The Light, Not Brightness, Or the Time

Why you want to sleep when it is dark and get up automatically when the sun comes back to life in the morning? Now there is a scientific reasoning behind our going to bed in night and getting up in the morning.

Scientists have found that the color of light tends to influence humans’ and animals’ internal clock. They have also claimed that this internal clock’s data actually assists the brain to know the time of the day.

Besides, scientists have also worked to understand the neurological mechanism for how our internal clock can measure changes in the light color that includes dawn and dusk.

According to them, they subjected the mice to different visual stimuli and recorded that electrical activity from the brain clock and they found that the neurons are more sensitive to changes in the color between blue and yellow than to the changes in brightness. They also measured the changes in the color and brightness at the top of the University’s Pariser Building for more than a month; this data was used to create a simulation for an artificial sky

Scientists, to their amazement, realized that same as it is expected for nocturnal animals, when mice was placed under the artificial sky for several days, the highest body temperatures was recorded just after the dusk, when the sky turned blue, indicating that their body clock was working optimally.

It is needless to say that the researchers are supremely excited about the finding. said Dr Timothy Brown from the Faculty of Life Sciences, who led the study says “This is the first time that we’ve been able to test the theory that color affects our body clock in any mammal. It has always been very hard to separate the change in color to the change in brightness but using new experimental tools and a psychophysics approach we were successful…What’s exciting about our research is that the same findings can be applied to humans. So, in theory, color could be used to manipulate our clock, which could be useful for shift workers or travelers wanting to minimize jet lag.”
