Reduced Stress Hormone (Cortisol)
Study conducted by University College London (UCL) and published by a journal, Psychopharmacology. In this research 75 health people participated that revealed that those who have taken black tea for duration of 6 weeks resulted in expressively decrease post-stress cortisol levels as compared to a placebo group, along with greater subjective relaxation.
Anti-Anxiety Effects of L-Theanine
A study conducted by Kristy Lu et al that published by leading journal, Human Psychopharmacology in 2004. It was comparison study with Alprazolam on Anticipatory Anxiety in Humans. The study clearly showed that the L-theanine, an amino acid found in tea is highly worthy in boosting relaxation without drowsiness. Studies shows that 200 mg of L-theanine decrease anxiety symptoms and boost sleep quality by generating feel-good neurochemicals, such as dopamine, serotonin, and GABA.
Green Tea's "Calm Alertness
Green tea produces an exceptional blend of L-theanine and caffeine. The research clearly reveals this combination enhance alpha-wave brain activity that led to a state of "calm alert" instead of the jittery energy commonly related to the coffee.
The "CE/TA" Ratio Rule
In 2024, study in Scientific Reports indicated that that green tea's stress-relieving properties are subject to the ratio of "relaxing" compounds (Theanine + Arginine) to "countering" compounds (Caffeine + EGCG). Shaded green teas including Matcha commonly contain lower ratios and are very worthy in reducing stress.
Usual Consumption Effects
In these Studies Japanese, adults have been involved highlighted that that consuming more than 5 cups of green tea daily was linked to lesser levels of psychological distress.

Though not from the tea plant, chamomile tea has apigenin that are acting on the same brain receptors as anti-anxiety medicines. Lemon balm and lavender teas are also effective in promoting the calm.
Limitations of Research
Even though the evidence is strong, some of the studies have noted that the dosage of L-theanine need for significant anxiety reduction. The doses like 200 mg) may higher than that found in a single cup of tea. Its consistent consumption may appear to offer the most notable benefits.
