A cup of tea can boost the brain power and increase alertness, say researchers.
For the research, Dutch scientists studied the brain activity in 44 young volunteers to analyze the effect of key chemicals, an amino acid called L-theanine, and caffeine at levels typically found in a cup of tea, News.com.au reported.
AdvertisementThe natural ingredients radically enhanced accuracy across a number of switching tasks for those who drank the tea after 20 and 70 minutes, compared with those who didn't.
The study also found that tea drinkers' had heightened alertness and were less tired as compared to their non tea-drinker counterparts.
Researchers added that the results of the study suggest that the combination helps to focus attention during a demanding cognitive task.
The study was published in the journal Nutritional Neuroscience.
