【Daily report, April 7, 2026】Did you know that there's a difference in the effects of caffeine in coffee and tea? The following article is based on AI research, but it perfectly reflects my own experience of guzzling drinks at beverage bars daily, so I wanted to share it with you with deep conviction. It seems that tea is better for mentally demanding tasks, doesn't it?

Coffee and tea work through different mechanisms to enhance concentration. Coffee is more effective for immediate and strong results, while tea is more effective for sustained and calming effects.

1. Coffee: Powerful Awakening and Immediate Effects
Coffee is characterized by its powerful boost due to its high caffeine content.
▷Caffeine Content: Approximately 90mg per cup (150ml), about twice the amount found in tea.
▷Mechanism: Caffeine blocks the action of adenosine, which induces sleepiness, and promotes the release of dopamine and other substances, quickly waking up the brain.
▷Suitable situations: Ideal for waking up first thing in the morning or for tasks requiring "instantaneous power" to quickly boost concentration.

2. Black Tea: Sustained "Gentle Concentration"
Black tea's greatest feature is that, in addition to caffeine, it contains "L-theanine," a type of amino acid.
▷Synergistic effect: Theanine has a relaxing effect (increases alpha waves) while simultaneously mitigating the stimulation of caffeine. This suppresses the "irritability (jitter)" characteristic of coffee, allowing you to maintain a "calm and sharp state of concentration" for a longer period.
▷Sustainability: Some studies suggest that polyphenols bind with caffeine, slowing down absorption and reducing the likelihood of energy depletion (crashing).
▷Suitable situations: Suitable for long hours of desk work, tasks requiring creative thinking, or maintaining concentration in the afternoon.

In conclusion, choosing coffee when you want to "get your brain up immediately" and black tea when you want to "think things through carefully without rushing" is a wise choice based on scientific properties.
...That's what they said.
