Green Tea

Green tea is another known stimulant that helps you remain alert. It contains two compounds that go a long way in influencing the brain.[20] First, it contains caffeine which accounts for the alertness. Although coffee contains a much higher quantity of caffeine than green tea, the latter is found suitable to use for those who prefer a well toned effect of caffeine. Caffeine helps with regulating neurotransmitters like norepinephrine, dopamine and adenosine, as earlier mentioned, that helps with keeping you awake and in good balance in terms of moods and brain function.[21][22] Second, it contains. L-theanine. L-theanine is an amino acid that can cross the blood-brain barrier and into the brain which then promotes increase in GABA (Gamma aminobutyric acid) which promotes relaxation.[23][24][25] It also increases the alpha waves in the brain which are responsible for the calm, conscious and relaxed mental state. When L-theanine and caffeine are combined, they both have a much powerful effect, and this explains why taking green tea for many people has been found more rewarding than coffee. L-theanine has also been linked to other mental health benefits such as improving memory and protection from mental illnesses like Parkinson’s and Alzheimer’s.[26][27] Taking green tea in the morning and just before going for a physical exercise helps.
