Blue light can keep people more alert than coffee

Melbourne: Researchers have revealed that blue light could be much more effective alternative to coffee.

The research done in the Mid Sweden University has found that blue light might be more effective to keep one alert, News.com.au reported.

The researchers set up an experiment where a hit of caffeine was given to one group of people, whereas the other group was exposed to blue light for an hour.

When the results from a series of brain function tests were compared, it was found that the blue light group had performed much better than the coffee drinkers in tests that included a distraction.

It was also found that blue light can be effective by making us more alert, but it needs to be used at the right time of the day, as blue light may give one a good jolt in the morning, but it also might do damage at night.
