Is green tea caffeinated？

Green tea is a world-recognised healthy beverage and many people enjoy drinking it. Whether green tea contains caffeine is a very important question. Caffeine is a strong stimulant and has a certain stimulating effect on the human body, so many people are afraid to drink food or drinks containing caffeine. So, does green tea contain caffeine? The answer is yes, green tea contains caffeine. However, the caffeine content in green tea is much lower compared to drinks such as coffee and cola.

The amount of caffeine in green tea is related to a number of factors, such as the variety of tea leaves, the time of picking, the production process and so on. In the process of making green tea, the fresh leaves are usually processed through a number of stages, such as killing, kneading and drying. Different processing methods will affect the amount of caffeine in green tea.

Caffeine is a neurostimulant that refreshes the mind, but it also tends to make people feel anxious and insomniac. For sensitive people, drinking green tea with caffeine may cause headache, stomachache, heart palpitations and other uncomfortable feelings.

In addition, caffeine has a diuretic effect. When drinking large amounts of green tea or caffeine-containing beverages, the amount of urine discharged will be increased, which may cause dehydration and lead to reactions such as thirst, dry mouth, and elevated body temperature.

In summary, although the amount of caffeine in green tea is relatively low, it is still necessary to pay attention to reasonable consumption for some people.
The amount of caffeine in green tea is related to various factors, such as the variety, the time of picking, the production process and so on. The caffeine content of the same variety of green tea varies according to the growing environment, picking season, fresh leaf processing methods and other factors, but generally speaking, the caffeine content per 100g of dried tea leaves is between 10mg - 50mg.

Compared to drinks with higher caffeine content such as coffee and cola, the caffeine content of green tea is about 15mg - 30mg per 100ml, which is much lower than the caffeine content in the same volume of coffee or cola. Therefore, green tea is a relatively safer drink and less taxing on the body.
