Exposure to blue light can improve brain health, says study
June 21, 2016 : Being exposed to periods short blue light can help boost subsequent activation in these brain areas that are important for successful performance of working memory thus resulting in improved reaction time, according to a recent study.
Anna Alkozei, the lead author of the study, said previous studies have shown that exposure to blue light (such as LED light) is almost similar to basking under the sunlight, which It leads to better alertness and better performance on tasks of response time. Alkozei is a well-recognized in the Department of Psychiatry at the University of Arizona in Tucson postdoctoral researcher.
The recent study revealed that exposure to blue light for about 30 minutes can help improve cognitive performance of tasks compared to amber light exposure during the same time.

The study was published in SLEEP 2016: 30th Anniversary Meeting of the Associated Professional Sleep Societies, scanning more than 35 healthy adults, of whom 18 were women. Participants were then exposed to blue light for 30 minutes without any particular order with the help of Philips goLITE BLU Energy Light device. This was followed by an assignment of working memory during functional MRI. Study participants were analyzed in the morning after a night of normal sleep.
After the evaluation, it was found that those who were exposed to blue light showed better activation in the ventrolateral prefrontal cortex and during the end of the task, compared to those who were exposed to yellow light. Ventrolateral prefrontal cortices and the are important regions of the brain that are responsible for cognitive performance of triumph.
In addition, those who were exposed to blue light experienced faster time reaction (p = .04), where they were able to respond to questions in a more accurate per second ( P =. 01).
