Coffee basic knowledge can not be refreshed by strong tea and coffee?

A Weibo

When people feel physically and mentally exhausted, they often make a cup of coffee or strong tea to refresh themselves. the caffeine in coffee and strong tea does have a "refreshing" effect, which can make people feel excited, but after excitement, they will feel more tired. It is suggested that when you feel tired and stressed, you should drink more boiled water, light tea and low-sugar fruit juices.

Ask for the truth

@ City KuaiBao National Health V: nutrition experts remind that over-reliance on strong tea and coffee will lead to health overdraft. If you are stressed, take a rest, don't hold on, and get enough sleep. Light tea and low-sugar diet play an auxiliary role in relieving fatigue, but plain boiled water does not.

Theory principle

Why will coffee, strong tea overdraw the body to aggravate fatigue? Because the nervous system can not be in a state of excitement for a long time, after excitement, the cells in the body begin to atrophy, and people will change from very excited to depressed. When the whole physical and mental system changes to a state of malaise, the blood flow of the whole body, which is accelerated by excitement, will naturally slow down. at the same time, the digestion of the gastrointestinal tract and the operation of the liver will all become slower than usual, and the body's resistance will also decline. Therefore, when young people are under great pressure from work and study, they always rely on coffee and strong tea to refresh themselves. after excitement, they will feel more strongly tired.

Light tea can help relieve fatigue because it contains a small dose of caffeine, which is less exciting and can properly ward off drowsiness. In addition, a diet containing sugars such as low-sugar fruit juices can excite nerves, especially the brain nerves, and eating a small amount of sugar can indeed play a relieving effect when you are particularly tired.
