Another reminder, in fact, tea alone is not enough for memory, and you must have enough sleep.
All the promotion of tea and coffee is to overdraw your physical strength. It worked at that time, but later it got tired, and the later it got worse.
The solution to the problem is to arrange your own work and rest time reasonably, and ensure that you sleep before noon every day (1 1 pm), and you can take a nap every noon (preferably between 12 pm and 1 pm).
One more thing, remember to have good living habits and avoid color. Many people's amnesia stems from having too much sex.
In terms of diet, pay attention to eating less spicy food.
The above guarantees that you have enough physical strength.
Back to the topic, if you want to buy green tea, it is recommended to buy safe and secure food, and the detection of pesticide residues meets EU standards.
