Deskripsi
The unique combination of caffeine and L-theanine in tea produces a state of calm alertness that enhances attention, working memory, and task-switching ability. Unlike coffee, tea's cognitive benefits come without jitteriness or anxiety. L-theanine promotes alpha brain waves (associated with creative, relaxed focus) while caffeine provides alertness. Studies show improved reaction time, accuracy, and sustained attention. Long-term tea consumption is associated with reduced cognitive decline in aging.
