Boosts Brain Functions
Caffeine, a natural stimulant, can boost brain functions and increase activity in the nervous system. The right dose of caffeine can improve a person’s mood, reaction time, and vigilance. It can also make a person feel more focused and refreshed. However, too much caffeine can cause addiction and increase the risk of dementia and Alzheimer’s. This is the good thing about green tea. It contains just enough caffeine to improve and boost brain functions without being too addictive like coffee.
Research also shows that green tea contains L-theanine, an amino acid that can improve mental functions and help people suffering from depression, cognitive impairment, extreme stress, and anxiety. Green tea can also increase dopamine, which plays an essential role in different body functions associated with mental health and neurological conditions.
Many studies also highlight the synergistic effects of green tea. For example, people who switched from drinking coffee to green tea reported having more stable energy, being more productive, and sleeping better at night. They also experience a milder but more sustainable boost in brain function compared to the sudden boost given by coffee.
