TEA AND MENTAL PERFORMANCE
A large number of studies suggest that tea may help address key health issues.

Theanine
L-Theanine is naturally present in tea. The amount in just 2-3 cups has been shown to stimulate alpha brainwaves which are associated with a relaxed but alert state of mind. Alpha brain waves are thought to be important when you’re juggling different tasks simultaneously. When faced with distraction, L-theanine helps you concentrate on the task at hand.
Caffeine
Tea also contains caffeine, which has been demonstrated to increase alertness and reduce fatigue. Caffeine makes you feel energised. The combination of theanine and caffeine in tea makes you feel relaxed but alert and helps you focus.
