What are the effects of caffeine?
Caffeine is a mild stimulant that contains less caffeine in our daily drinks such as tea, cocoa and chocolate. Caffeine is also found in carbohydrate drinks such as cola and some anesthetics. It can accelerate the metabolism of the human body and keep people clear-headed and sensitive. So there are a lot of wonderful little white-collar workers who need to stay up late to refresh themselves with coffee.
Caffeine can stay inside the body for several hours, and the effect on the body is appropriate for each person. Some people will lose sleep after drinking coffee at night, while others will be nervous and overexcited when they drink too much coffee, but many people will not be affected at all, depending on how everyone's body reacts to caffeine. like the editor has become accustomed to drinking coffee, ordinary instant coffee can no longer play a refreshing role.
The caffeine in coffee is insoluble in cold water, but easily soluble in hot water. It will stimulate the cerebral cortex, eliminate drowsiness, enhance the sense of touch and thinking and adjust the function of the heart, but also dilate kidney blood vessels, diuresis and so on. However, caffeine is not limited to coffee. Usually a cup of 100cc coffee contains caffeine 60~65mg, green tea has 200~300mg, black tea has 350~400mg, and cocoa has about 100mg. Excessive caffeine intake is prone to tinnitus, hyperfunction of the heart (rapid heartbeat, increased pulse frequency), and uneven pulse, so some people are not suitable for drinking coffee.
