Tea and your brain
It’s long been known that tea is good for you, it is a natural cleanser for the body and replenishes essential nutrients and minerals, but in recent years it has also been noted that it is good for your brain too.
Components in tea called catechins, L-theanine and caffeine all have effects on our mood and cognitive functions with the latter two items joining together to increase human alertness and attention switching accuracy. This effect has been measured to last up to two hours after consumption. Tea also had a marked, although small, effect on hearing and visual attention too.
Sadly the research failed to find a link to the often suggested link to drinking tea and providing people with some kind off protection against the development of dementia.
