What are the effects of caffeine on the body?
Caffeine is a natural alkaloid that stimulates the central nervous system. It has effects such as refreshing the mind, enhancing attention, and improving psychological state.
However, it's important to note that the daily intake of caffeine should ideally be kept within a certain range. For healthy adults, the recommended daily caffeine intake is typically between 300 milligrams to 400 milligrams.
Excessive consumption of caffeine may lead to the following symptoms:
Overstimulation of the central nervous system
Increased blood pressure
Irregular heart rhythm
Decreased appetite
Nausea and vomiting
Insomnia
Caffeine Content in Coffee
In general, a regular cup of coffee containing approximately 100 milliliters typically has a caffeine content ranging from 30 to 100 milligrams. The caffeine content can vary depending on the type of coffee beans used.
Additionally, factors such as brewing methods, including steeping time and water temperature, can also influence the caffeine content in coffee.
Caffeine Content in Oolong Tea
Generally, a 100-milliliter serving of oolong tea typically contains 15 to 40 milligrams of caffeine. The caffeine content in the brewed tea can vary based on the specific type of loose leaf oolong tea. As a general rule, the higher the oxidation level of oolong tea, the higher the caffeine content in the brewed tea.
Similar to coffee, the brewing method for oolong tea also significantly affects the caffeine content in the tea infusion.
In summary, the caffeine content in a cup of oolong tea is generally lower than that in a cup of coffee. If you are looking to reduce your caffeine intake, replacing coffee with oolong tea as a daily beverage is a good option. Where to buy Oolong Tea?
