Green tea for improved concentration and clarity of mind
Green tea for improved concentration and clarity of mind
In today's increasingly competitive world and where we often feel stressed and overwhelmed, we often look for ways to improve our cognitive performance. One way to do this is by consuming green tea. Green tea has a long tradition in Asian culture for centuries as a drink that calms the mind while increasing energy levels. In this article we will take a closer look at the effects of green tea on brain function and concentration.
Green tea contains a unique combination of caffeine and L-theanine, which have a synergistic effect on brain function. Caffeine is a stimulant that increases activity in the central nervous system and improves mood and alertness. L-Theanine is an amino acid found in green tea that has a calming effect on the brain. Together they improve cognitive performance and promote concentration.
A 2017 study examined how the combination of caffeine and L-theanine affects cognitive performance. Participants received either a combination of caffeine and L-theanine or a placebo. The results showed that the group that received the combination of caffeine and L-theanine had significantly better results in attention, reaction time and accuracy than the placebo group.
Another 2014 study examined the effects of green tea on cognitive function in older people. Participants received green tea or a placebo. The results showed that the group that received green tea had a significant improvement in cognitive function, particularly in the areas of working memory and executive function.
In addition to the combination of caffeine and L-theanine, green tea also contains other compounds that can improve brain function. One of these compounds is EGCG (epigallocatechin gallate), an antioxidant found in green tea. It has a neuroprotective effect and can help protect the brain from damage caused by free radicals.
Green tea can also help reduce stress, which also helps improve brain function. Stress can impair cognitive performance by reducing concentration and attention. L-Theanine in green tea can help reduce stress by calming the brain and promoting the alpha wave production process, resulting in a relaxed and focused state of mind
