Colour helps our body clock or Circadian Rhythm adjust time
Humans and animals biological clock doesnâ€™t depend on the brightness of the time or the hour. A latest study claims that the biological clock among animals largely depends on the color of the light.
The study claims that the color or the appearance of the light does have a significant impact on the way the brain’s clock measures the time of day.
There is no denying the fact that this is the first study that comes out with a neuronal mechanism for how the internal clock measures the changes in light color present at dawn and dusk, PLOS reported. Researchers reportedly looked at light color present at different times of day to determine if it could be used to tell the time. Scientists claim that at twilight, the light is much bluer than it is during the rest of the day.
On the other hand scientists working on the study also recorded electrical activity from the brain clock while mice were shown a variety of visual stimuli, revealing many of the brain’s neurons responded more strongly to changes in color than brightness.
While talking about the findings study leader Timothy Brown from the Faculty of Life Sciences said, â€œThis 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 successfulâ€¦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 travellers wanting to [minimize] jet lag.â€
